Mauna Loa Volcano Awake Almost 40 Years

Mauna Loa Volcano, located on the Big Island of Hawaii, has been awake for nearly two years, and has finally erupted in late November.

This imposing volcano is one of the most active in the world and its activity reveals fascinating insights into geology and Earth's shifting landscape.

In this article we explore what an 'awake' Mauna Loa means for locals, scientists and hikers alike.

Mauna Loa Volcano: Exploring Its Recent Activity


Mauna Loa is the largest volcano on Earth, located in Hawaii.

It has been active since its formation thousands of years ago and continues to show signs of activity today through periodic eruptions.

Over the past two years, Mauna Loa has awakened again with a series of small earthquakes that have caused concern among scientists and residents alike. Prior to this activity the last eruption was not since 1984. 

From December 2018 to July 2019, there were 619 small magnitude earthquakes detected near Mauna Loa Volcano’s summit region (at depths less than 5 km).

Scientists believe these quakes are related to magma movement within a shallow magma reservoir close beneath the surface—an indication that new eruptions were likely years down the road, and it finally happened.

What makes this event so interesting and noteworthy is not just its size but also its duration; most seismic swarms associated with volcanoes typically last only weeks or days whereas this one has lasted an entire eight-month period.

The fact that seismic activity continued for such an extended time frame tells us something important: it was likely driven by pressure from large amounts of trapped gas rather than rising molten rock inside a shallower chamber below ground level.

The eruption occurred as pressurized gasses like carbon dioxide rose with the molten rock fast enough to the surface. The expanding gasses and materials lead to big explosions as the energy is rapidly released, sometimes in spouting lava plumes. 

As part of ongoing monitoring efforts, Hawaiian Volcano Observatory (HVO) staff took measurements several times during April 2020 showing increases in sulfur dioxide gas emissions at both Kilauea Summit and lower East Rift Zone vents, as well as changes in temperature consistently throughout those locations, indicating flow pathways which connect distant regions across multiple areas spanning tens of kilometers .

This data reveals that pressure is building inside the volcano to critical rates and future eruptions could occur relatively quickly until the molten materials are dispensed.

Understanding how volcanoes behave requires lots of data analysis compiled from various sources, including remote sensing technologies such as satellites equipped with infrared cameras able to detect heat radiating off the landscape for potentially hazardous hot spots. Field observations closely study features occurring in the surroundings using ground-based instrumentation to track and measure subsurface conditions. The data surveys atmosphere pollution particles in order to assess impacts on the environment to manage land usage for safety purposes. Gathering observations allow for risk analyses to proactively protect affected communities from any future disaster scenarios and identify signs of a possible imminent threat posed to nearby populations.

Mauna Loa's recent awakening provides valuable insight into predicting volcanic behavior: • Insight into pressurization levels behind quakes linked to specific movements happening in deeper chambers, providing better identification strategies for gauging levels of risk in the front-end model. Better identification strategies will aid emergency communication, accordingly helping avert disasters if spotted early enough.

Challenges Facing The Monitoring Of A Restless Giant

Scientists have been closely monitoring Mauna Loa for the past two years, as its state of unrest signaled potential eruptive activities. 

The volcano is located on Hawaii’s Big Island and rises 13,680 feet above sea level.

As one of the world’s most active volcanoes, its activity can cause significant disruption to communities living nearby or even downwind from it.

 

Here are some of the challenges facing scientists and other authorities as they monitor this restless giant:

1) Inadequate Resources – Monitoring such an active volcano requires constant surveillance including ground deformation measurements, seismic monitoring equipment, aerial photographs and real-time satellite imaging to identify possible eruptions before they occur.

Unfortunately, these efforts require substantial financial resources that many cash-strapped governments lack; consequently, dangerous situations may go unnoticed until it is too late for action.

 

 

2) Difficult Accessibility – Many parts of Mauna Loa are quite remote and difficult to access quickly by personnel when necessary, such as during earthquakes or volcanic eruptions when reliable data must be collected quickly without endangering anyone involved in the mission.

This limitation not only makes monitoring more challenging but also results in inaccurate information being captured due to longer response times, which ultimately leads to false alarms that could potentially result in unnecessary evacuations and widespread panic among populations near potential hazards caused by geological events still happening deep underground in off-site locations.

 

3) Hazards To Personnel – While measuring Mauna Loa’s earthquake activities, seismologists often have to come close enough to place their recording instruments around lava fields while running current risk assessments on potential present dangers. The high risk environment not only involves themselves but also residents living within areas perceived at harm because of possibly misplaced predictions during geophysical studies. 

These are the reasons why people get paid large salaries to get up close to the volatile volcano, doing what others wouldn't dare try anyway. Many tourists travel to Hawai’i to see the volcano, getting extremely close to the dangerous lava fields despite countless warnings now visible everywhere. Increased global attention and foot traffic have made this process perhaps even more risky than usual when confronting unpredictable forces beyond human control.

Officials have established barriers and road closures to prevent people from wandering into unstable areas, and geologists are constantly monitoring ongoing activities. Already the eruption has experienced many changes and its lava is slowly expanding down its slopes towards roads and other infrastructure. 

 

4) Technology Limitations

- A common challenge faced by those tasked with studying any natural phenomenon occurs when inadequate technology fails to get accurate readings from volcanic emissions floating through air as conditions greatly change over short periods.

Volatile changes require advanced tools and techniques to obtain reliable quantifications.

Untrustworthy data might disrupt communications causing mistaken decisions to result in serious delays and unfavorable outcomes despite the official's best efforts.

Earth’s Future, Now With 8 Billion Humans

Humanity has long been chasing that 8 billion number for our global population. As of November 2022, we have surpassed it with only increasing trends in sight. With such a large international population and growing numbers, what kind of new stressors will be placed on the planet? 

Global warming is already a direct indicator of influence on the planet. Humans have permanently changed how we interact with Earth's natural resources, but now it's clear that the reliance on those resources will be put to the utmost test. Populations will put immense pressure on nature, forcing humans to compete with other wildlife for water, food, and materials.

The problem not only arises with the total size of the global population but also with the rapid timeline to the astronomical number. Global population sizes previously always remained below 1 billion people on the planet at any given time until the late 18th century during the time of Napoleon. Rapid growth began to influence global numbers after the start of the Second World War when more than 1 billion people were added to the global population every 12 to 15 years. Key events spurred rapid growth over the last 300 years, including the industrial revolution, medical discoveries, technology, and global commerce trade. Currently, the human population is more than double what it was in 1970, doubling in just over 50 years.

Population analyses over the last few decades also draw attention to the uneven growth experienced worldwide. China and the USA are two places where population growth has been slowly leveling. At the same time, low-income regions like Sub-Saharan Africa and India are responsible for approximately 70 percent of the world’s population increases. There are difficulties to be faced in both scenarios because with leveling population growth, fewer individuals will support the enormous economies, and exponential growth in developing countries will continue to exacerbate already strained systems. The other caveat to increased global numbers is its likelihood to influence mass migrations and conflicts and further jeopardize at-risk environments. 

Experts are forecasting slower growth trends in the future, even though the population trends have been increasing exponentially. Their conclusions draw from increased knowledge and dispersal of contraceptives and safe sex to lower-income countries. Other factors influencing level growth trends include increased women’s rights worldwide, younger generations waiting to have families, and economic pressures driving living rates through the roof for most high-income countries. These forecasts are good news for slowing global population growth. Still, the world will likely not observe decreases until the latter half of this century, as fertility rates and population deaths will be important contributors to change. 
The urgency to allocate new green energy resources before it is too late is becoming increasingly evident. Experts agree that installing sustainable energy resources for low-income countries will greatly decrease their carbon emissions by supporting increasing population demands. Other changes must also be made in high-income countries responsible for more than double the carbon emissions released by the poorest half of the world.

Human Rights Violations Amidst Qatar World Cup Controversies

This year’s Fifa World Cup will be held on November 20th in Doha, Qatar, and will be the first time in the Middle East. The overall cost of hosting this year’s world cup has been estimated at upwards of $200 billion USD as Qatar has invested in creating seven new stadium venues to host the 32 teams and 64 matches spanning the games. Controversies have plagued the developmental agenda for the Doha world cup since the country began its ambitious construction on the venues 10 years ago. As it draws nearer to completion, many controversies have been at the forefront of media coverage, with allegations of human rights violations and deaths throughout the development process. 

Committing to hosting the Fifa World Cup is a complex request as the event will attract more than 1 million attendees and close to 3 billion virtual spectators. Due to Qatar’s position in the middle east and economic standing, they had to establish all new venues to accommodate the influx of tourists that will arrive later this month. The overhead cost of $200 billion USD has contributed to developing those arenas, ceremonies, workshops, press, housing, and sales. The country has enlisted the help of hundreds of thousands of migrant workers over the last 10 years; however, human rights activists have highlighted the many unsafe conditions, low pay, and faulty system trapping workers in their jobs developing the venues. 

Many migrant workers coming to Qatar are from India, Pakistan, Nepal, and Bangladesh. They were promised substantially increased wages compared to their home countries, although many were unaware of the Qatari employment systems and conditions they would face. The daily life of migrant workers often includes 12 hours of manual labor in temperatures upwards of 100 degrees Fahrenheit. These people were delegated to live in squalid and overcrowded worker camps on the outskirts of developments. The exploitation continued as Qatar is one of the world’s richest per capita countries. It also has many complex employment laws governing its migrant workers. 

A major injustice argued by human rights activists included the highly controversial kafala system whereby migrant workers had to sign away rights to Qatari companies to get a sponsored visa. The sponsors withheld passports, rewrote contracts, and often withheld wages. Employers also required recruitment fees to be paid by workers forcing them into debt with the companies, going months without sending money back to their families in need. Migrants were entirely helpless as the systematic laws also prevented them from leaving the country, changing jobs, or protesting as demonstrating is illegal. 

Immense pressure from the world cup administration and fans resulted in reforming and removing the kafala system towards these migrant workers in 2019. The reformation did improve their working conditions; however, two years later, it is still evident that the weak implementation of the changes still resulted in missing wages, extraneous hours, outrageous recruitment fees, and legal dilemmas for migrant workers. Amnesty groups characterize the workers' condition as a form of modern slavery, with very little rights protection outlined in contracts and virtually no freedom to unionize or gather fair wages in these developments. 
The dangerous conditions have also resulted in tens of thousands of migrant deaths over the last decade in relation to the world cup developments. Many deaths have resulted in outcries from cup supporters and fans who want to see intense reformation in the Qatari facilitation of these people. While some reformations have begun, the weak implementation by officials and lack of resources delegated to the migrant worker has not improved the overall conditions and slavery-type work. The Fifa president and governing body have urged players and fans to focus on football and not to get dragged into the ideological or political battles surrounding the location of the games. Response to their statement has garnered mixed reviews as many amnesty groups condemned the views as hypocrisy and a stark ignorance of these serious human rights issues.

Autoimmune Diseases Linked to the Black Plague

The Black Death was an unimaginable pandemic that swept through Europe in the mid-1300s, resulting in catastrophic and severe mortality of the global population at the time. The seven-year plague was responsible for up to 200 million deaths, a significantly more significant impact than the current coronavirus pandemic responsible for around less than 6.6 million deaths. Researchers studying gene mutations and modern human DNA recently discovered links between historic Black Death survivors and autoimmune diseases currently affecting millions of people.  


The significance of the Black Death’s impact at the time also coincides with a much smaller global population of around 392 million people, explaining why the plague had such an enormous impact and required centuries for the world to recover from the devastation. The plague was responsible for removing 30 to 60 percent of the European population at the time, meaning many modern humans of European descent originated from the remaining survivors. 


The enormity of the plague’s impact shaped humanity’s evolution, forcing the selection of survivable traits, which the researchers could observe in skeletal remains and descendants of the survivors. DNA analyses from the skeletons of plague survivors discovered genetic mutations that may have been the reason for greater individual survivability. The DNA study published in Nature found a series of mutations around the ERAP2 gene, equating to a 40 percent greater chance of surviving the plague for sampled individuals. 


The ERAP2 gene is responsible for generating proteins that divide and disperse invading microbes to immune system defenses, allowing it to recognize and neutralize invaders effectively. Survivors of the plague had mutations creating a high-functioning version of the gene, allowing their immune systems to overcome any infections by the deadly disease better. These plague-resistant mutations are still prevalent in today’s modern society as they were passed down through generations. However, modern-day humans may be inadvertently affected by those same high-functioning qualities of the mutations.


The massive impact the Black Death had on earlier human populations has continued to affect modern-day society, implicating descendants of survivors with damaging health consequences. Scientists discovered the increased protein production from the high-functioning gene can be linked to various autoimmune disorders like the damaging inflammatory bowel disease called Chrons. Increased protein production by the specific genes consequently has a negative implication forcing the body to damage itself in response to minor microbial invasions or even the lack thereof. The correlation of the plague’s evolutionary impact to modern autoimmune diseases is baffling but will potentially lead to discoveries regarding these diseases’ origins and treatment. 


Human DNA studies are incredibly complex as they attempt to understand many factors like mutations, environmental pressure, survivability, and inheritance. Similar consequences caused by the Black Death are improbable in the wake of the ongoing coronavirus pandemic. Future descendants of covid survivors will not likely need to address mutation complications because of the low significant impact on global populations and the disease’s inability to impact humans over a diverse age spectrum. Coronavirus-19 statistically has the most significant impact on older people, with deaths over 65 accounting for more than 75 percent globally.

Hurricane Ian’s Impact Lingers Amidst Climate Change Implications

Hurricane Ian quickly developed into one of the deadliest hurricanes to hit Florida since 1935, and one of the worst natural disasters in recent years for the United States. Damages from the hurricane are still being evaluated with early estimates totaling more than $60 billion USD alone in damages to infrastructure and properties. This large category 4 hurricane slammed into the Florida coast toward the end of September resulting in significant coastal damages, inland flooding, massive runoff, and large community displacements. Florida experiences many hurricanes each year, but it is now clear that the severity of the storms is increasing as they are exacerbated by the effects of climate change. 

Hurricanes are a natural aspect of the Caribbean and Gulf of Mexico geography, as conditions in late summer and early fall often generate cyclonic storm cells. A majority of south Florida lies at or below sea level putting many areas at increased risk for minor swells and ocean surges, regardless of storm activities. Florida has invested significant federal and state funds into coastal defense barriers like sea walls, sand dunes, foundation fortifications, and emergency aid response programs. These efforts seem to mitigate many damaging effects, but their effectiveness continues to wane as warming ocean temperatures increase the intensity of these Atlantic storm cells.

Climate change has a variety of negative effects on Earth, specifically intensifying the strength and frequency of destructive storm cell activities. Warmer coastal waters increase surface evaporation, rapidly accelerating hurricane wind speeds and the overall strength of the hurricane. Factors like warming climates, more intense storms, and continued development along the coast of at-risk regions like Florida have also increased the susceptibility of people and infrastructure to extensive storm damage. 

President Joe Biden addressed the nation after surveying the damages of the fierce storm, highlighting its similarities to many other significant natural disasters affecting other regions of the country. He indicated how climate change is responsible for many of the extensive damages caused by this storm, the fires in the midwest, and water shortages on the west coast. The increasing vulnerability of many regions affects more than the durability of the infrastructure, also implicates community health and long-term safety. 

As the aftermath of Hurricane Ian continues to be surveyed, it is clear this storm has impacted a multitude of resources, regions, and people across Florida. Many of Florida’s main waterways are now filled with contaminated pollution as a result of the upstream storm surge inundation and coastal runoff. Organic matter, chemical pollutants, and refuse washed off the land from torrential precipitation leading to additional negative environmental impacts. Environmental scientists suggest the pollution could damage aquatic ecosystems posing short-term dangers to human and resource health, while also subjecting these fragile ecosystems to additional long-term challenges. 
With the increasing intensity and frequency of storms like Hurricane Ian, similar events are likely to become more normal in the future. For at-risk regions, preparing the necessary infrastructure and response teams is vital to adequately handle estimated damages. These damages include factors impacting infrastructure, human health, environmental well-being, and long-term effects. Over the past decade, the United States has already had multiple examples of these effects as climate change continues to increase natural disaster intensities and frequencies.
