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.

Increasing Shipping Tolls to Inflate Medical Supply Costs in 2023

Increasing transit tolls for passage through the Suez Canal may result in increased costs associated with healthcare, medical products, and various other consumer industries. The Suez Canal will increase its toll rates for ships using the maritime route connecting Europe to Asia. Expected increases will begin in January of 2023, raising vessel toll rates by 15% for freighters and 10% for dry cargo and cruise ships. Amidst the ongoing pandemic conditions still affecting many regions of the world, access to affordable healthcare and medical products will inevitably succumb to increases as almost 90% of global trade is facilitated through the vital canal. 

The geographic significance of the Suez Canal places it centrally between Europe, Asia, and the Middle East. Before its development essential commodities, medicine, and health supplies had to make the arduous journey around Africa’s Cape Horn. Bypassing the southern route for the Suez Canal can reduce shipping time by more than seven days and save substantial money. The decision for the increased toll rates for this vital shipping route arose as higher than average rates of vessel traffic returned amid pandemic recovery, technological advancement in vessel utilization, and continued impacts facing congested shipping ports globally. 

The Suez Canal is often described as the artery at the heart of global trade because a majority of trade is facilitated through the canal that connects the Mediterranean with the Red Sea. The canal observed more than 12% of all global trade and 30% of global container traffic each year. These large shipping containers utilize the much faster route to rapidly deliver critical commercial goods, energy, medicine, and industrial components. 

As the coronavirus spread globally in early 2020, catastrophic maritime operation reductions in many ports forced freighters to opt for longer routes affecting their deliveries. The massive redirection of freighters during this time congested areas like the Suez, inadvertently forcing ships into smaller ports not designed to accommodate such a large influx of activity. The effects left medical professionals and the public without access to vital medications, tools, and equipment during a worldwide pandemic. The results of the congestion are still unraveling today, reinforced by the recent canal blockage by a cargo freighter in early 2021. The ship got stuck traversing the canal, blocking any passage by other vessels in the queue. Without an active channel to transport the ships, a gridlock of more than 100 vessels piled up on both sides of the canal, further contributing to the already delayed global trade industry. 

After the 2021 blockage was cleared and signs of the pandemic began relaxing, maritime shipping rapidly increased past former heights as countries attempted to account for the economic losses of the last few years. This rapid traffic influx forced the canal to support the passage of more than 50 vessels per day. Additional advancements in vessel utilization has greatly improved larger freighter’s overall performance, extending their transport range and volume. The canal managers are worried that without adequate funding to support the growing daily use of the route, more accidents like the blockage of 2021 will occur and contribute to future stock shortages, delays, and restricted access to healthcare tools.  

It is highly likely the health industries will face price inflation as the cost of consumer goods increase to match shipping costs. More than $1 trillion USD worth of global commerce industry goods pass through the canal each year. Potential welfare effects may impact less developed regions as healthcare costs also increase to afford inflated medical supply costs. Additional revenue generated by the 2023 toll increases is expected to reinforce the canal, prevent future blockages, and maintain increasing influxes of global traffic. Whatever changes American consumers face regarding the toll increases, the associated costs will still be more affordable than any commodity delivered via longer alternative shipping routes.

Dangers of Extreme Heat Faced by Outdoor Workers

Many outdoor workers face a common problem every year: managing summer heat and health complications while on the job. Summer temperatures in southern regions of the United States and other parts of the world are increasing yearly, posing additional risks to these types of employees. However, the risks and complications are not equally imposed, and different types of workers may be at even higher risk, according to experts. 

Three of the hottest cities in the United States where workers are at increased risk include Phoenix, Los Angeles, and Las Vegas. Certain studies have explored the relationship between heat indexes in these southwestern states and work-related injuries, revealing expected trends toward higher temperatures and people getting sick. 

These higher-than-average temperatures often reach more than 88°F during the summer and can cause many health complications. Extended exposure to exorbitant heat can result in dehydration, unconsciousness, heat stroke, and lack of perspiration. Severe heat exposure cases can damage internal organs, disrupting the central nervous system, blood clotting, liver functions, and kidneys.

Due to complications imposed by global warming, summer temperatures continue to increase and expose workers to heat waves, droughts, and higher temperatures. Outdoor workers that face these temperature challenges include industries such as agriculture, construction, maintenance, recreation, and more. Heat-related injuries can keep workers out of a job, sometimes up to 30 days, while healing. The extended recovery times for workers who have experienced heat-related injuries can significantly impact employees and their families. The risks of these work-related injuries impact the lower-class workers at an even higher rate. Researchers also discovered a higher percentage of female workers reported heat-related injuries.

Studies between 2011 and 2018 suggested an increase from 50 to 86 percent of people affected by work-related heat injuries identified as female. The increase in the disproportionate cases of affected female workers may result in more women entering the workforce, specifically into roles within outdoor industries. These results have inspired further research into the hormonal risk component associated with the different heat risks between sexes. Specific biological cycles may place women at higher risks than their male counterparts. 

Another demographic at greater risk of heat-related injuries includes long-standing employees. The same study found that increased work heat complications correlated with increased length of stay at the worker’s company. Employees with five or more years of experience were at a greater risk of work-related heat injuries than employees with less than one year. Experts suggested the increased risk of these long-standing employees may be due to the lack of risk perception or the cumulative tolerance built from chronic heat exposure during their years of service. 

More research is being conducted on the types of employees at the most significant risk and different safety methods these vital outdoor industries can implement to decrease heat-related health implications.

California in the Dark Amidst Environmental Regulations

Californians are sweating, and in the dark as sweeping new environmental regulations, healthcare, and climate change contribute to rolling blackouts across the state. California is home to the world’s fifth-largest economy, boasting a GDP of more than 3.4 trillion USD. The state is occupied by more than 39 million people and accommodates more than 213 million people annually. 

This state has had its fair share of financial difficulties accommodating such large population sizes as global climate change continues to increase environmental pressures on the region’s resource accessibility. Many of California’s largest cities have suffered ongoing climate changes that have reduced accessible water, energy, and moderate temperatures. The majority of California’s resources are delegated to the densely populated lower two-thirds of the state, where problems were initially acknowledged more than 100 years ago when people started mass settling in the early 1900s. 

Sweeping environmental and renewable energy reforms over the last decade have put the state in a place where it can supply most of its energy needs with solar power during the day. However, the energy storage from the solar sources is insufficient to supply the large demographic at night and in the summer, leading to rolling blackouts and intermittent periods of energy shortages. These unfortunate events often happen during the summer when extremely high temperatures in the state's southern portion exacerbate high energy usage, often fueling high taxing air conditioning units in both the private and public sectors. 

The lack of adequate energy resources and continued climate change increasing environmental pressures on the region have forced lawmakers like California governor Gavin Newsom to sign bills facilitating the implementation of fossil fuel subsidies. The fossil fuel legislation contradicts many of the environmental principles California is slowly shifting toward as they move toward a green economy. The governor argues that the state’s use of fossil fuels is necessary and unavoidable as the current renewable sources do not have the facilities to accommodate the state’s needs effectively. He told reporters that these fossil fuel bills are simply buying time for the state’s residents until additional renewable storage facilities can be produced.

Proponents on the fossil fuel side of the debate argue that the governor’s new legislation proves the state needs to utilize already established oil and gas industries instead of completely switching prematurely to renewables before the industry is fully developed. Energy shortages can be extremely detrimental and even deadly, especially with summer temperatures often exceeding more than 86 degrees Fahrenheit. 

Environmental groups have also criticized the state’s decisions explaining there would have been adequate renewable storage facilities available in the state had moved faster to establish the industry amidst earlier concerns and initial environmental legislation. Many environmentalists also argue the new bills lack clearly observed limits to prevent fossil fuel expansion across the state, and reduced regulations on industry leader’s development protocols can significantly impact local environments. 

Building an electrical infrastructure will be an environmentally safe and effective method for reducing fossil fuel use. California is among the first states to lead the movement and the system’s complex logistical problems. There are many sides to the debate, but the current industry is not supplying enough energy for California residents and businesses. 

The Dangers of Public Wildlife Interactions in National Parks

National park officials and wildlife managers each year stress the importance of maintaining a safe distance from wildlife. Summer traffic causes wildlife encounters to be at an all-time high. Most wildlife encounters occur during the summer between May and September as more than 100 million visitors enter national parks across the United States. These parks host wildlife that can threaten human life, including snakes, mountain lions, moose, bison, bears, and wolves. Wildlife interactions only become dangerous when visitors disregard safety measures put in place by park officials, often getting too close while taking pictures for social media.

Many of these animals will only attack if someone invades their personal space. Far inside what national park officials recommend for safe viewing, a 25-year-old woman was gored to death by a bison in Yellowstone National Park after approaching the animal within less than 10 feet. The park officials stated the woman and two others were threatening the animal by coming within 25 feet, causing it to respond by stampeding and goring her to death. Witnesses stated the woman was tossed more than 10 feet into the air, while the two other people who also approached the animal escaped. 

The tragic encounter prompted officials to restate their recommended boundaries when encountering wildlife in hopes of preventing further interactions this season. Yellowstone officials recommend visitors stay at least 25 yards away when interacting with large animals like bison, deer, bighorn sheep, and elk. When interacting with predatory animals, they recommend maintaining more than 100 yards if possible to avoid deadly encounters with bears, wolves, and mountain lions.

The bison in Yellowstone park have injured more people than any other animal as they stand more than 6 feet tall, weigh more than 2,000 pounds, and can easily run three times faster than a human. They often graze in highly trafficked areas near roads and buildings, leading to more frequent close encounters than other types of wildlife—the bison population numbers more than 20,000 across the United States National Parks. High population densities in some parks have posed challenges for effectively managing human interactions, leading to proponents advocating for population control in certain park areas. 

Dangerous wildlife encounters occur every year in the national parks. Recent wildlife encounters this season have caused the same concerns as many national parks across the United States have begun enforcing daily reservations and timed entry tickets. Reservation implementation originated from efforts to limit the spread of covid amongst park visitors. Park officials are investigating all efforts to keep people safe and continue managing their wildlife.

Here are three safety tips to keep in mind if you venture out into the wilderness this summer. 

1. Do not feed the animals because this could lead to incitement resulting in small bites from even the smallest animals to an all-out predatory attack.

2. Do not pet or approach wild animals as they can be unpredictable and easily provoked.

3. Report close animal encounters to park officials so they can be attentive and monitor the animal's behavior.
