Magnitude & Depth

The earthquake that appeared on August 15, 2021 05:06:04 had a magnitude of 1.7 on the richter scale.

Shallow earthquakes are considered between 0 and 70 km deep, while intermediate earthquakes range from 70 - 300 km deep and deep earthquakes are between 300 - 700 km deep.

Are shallow earthquakes more destructive?

Shallow quakes generally tend to be more damaging than deeper quakes. Seismic waves from deep quakes have to travel farther to the surface, losing energy along the way.

Power Plants & Risks During Earthquakes

We found 7 types of power plants in the vecinity of the magnitude 1.7 earthquake that struck 0 km S of Woodlawn, Maryland on August 15, 2021 05:06:04. These types were Nuclear power plants, Biomass power plants, Oil power plants, Waste power plants, Coal power plants, Gas power plants, Solar power plants, below you find information how each type of power plant can pose a risk to you as a person or the ecosytem around you.

None of this information should be used as guidence in an event of an emergency, but rather as additional references to information provided by national, state and local authorities.

Nuclean Power

Nuclear power plant bear an inherent risk during earthquake events, as we all witnessed on 11 of Mars 2011 in Fukushima. However, According to the World Nuclear Association, nuclear facilities are designed to witstand earthquakes.

"Nuclear facilities are designed so that earthquakes and other external events will not jeopardise the safety of the plant. In France for instance, nuclear plants are designed to withstand an earthquake twice as strong as the 1000-year event calculated for each site. It is estimated that, worldwide, 20% of nuclear reactors are operating in areas of significant seismic activity. The International Atomic Energy Agency (IAEA) has a Safety Guide on Seismic Risks for Nuclear Power Plants. Various systems are used in planning, including Probabilistic Seismic Hazard Assessment (PSHA), which is recommended by IAEA and widely accepted."

"Peak ground acceleration (PGA) or design basis earthquake ground motion (DBGM) is measured in Galileo units – Gal (cm/sec2) or g – the force of gravity, one g being 980 Gal. PGA has long been considered an unsatisfactory indicator of damage to structures, and some seismologists are proposing to replace it with cumulative average velocity (CAV) as a more useful metric than ground acceleration since it brings in displacement and duration and "operators are able to determine the absence of potential damages with high confidence" according to the IAEA."

"The logarithmic Richter magnitude scale (or more precisely the Moment Magnitude Scale more generally used today*) measures the overall energy released in an earthquake, and there is not always a good correlation between that and intensity (ground motion) in a particular place. Japan has a seismic intensity scale in shindo units 0 to 7, with weak/strong divisions at levels 5 and 6, hence ten levels. This describes the surface intensity at particular places, rather than the magnitude of the earthquake itself."

Gas Power

Gas power plants can pose significant risks to people and the environment in their vicinity during earthquakes.

Gas Leaks and Fires

Gas power plants rely on natural gas, which can leak from pipelines and equipment when damaged by seismic activity. These leaks can lead to fires and explosions, endangering people in the plant's vicinity.

Impact on Air Quality

Gas power plants emit pollutants, and fires caused by gas leaks during an earthquake can release harmful substances into the air. This can pose health risks to nearby residents.

Environmental Impact

Gas leaks can also harm the local environment, potentially contaminating soil and water sources.

To mitigate these risks, most modern gas power plants have robust safety measures in place, including gas leak detection systems, emergency response plans, and communication protocols to alert nearby communities in case of an incident. Additionally, local authorities should conduct risk assessments and ensure that emergency services are well-prepared to respond to potential hazards posed by gas power plants during earthquakes.

Solar Power

Solar power plants generally pose fewer risks compared to conventional power plants that use fossil fuels or nuclear energy. However, they are not without their own set of potential risks and challenges. Below you can find some of the risks associated with solar power plants in an event of a severe earthquake.

Environmental Impact

The production of solar panels involves the use of various materials, including rare metals and chemicals. Severe earthquakes could potentially introduce these into the ecosystems of their location.

Fire Risk

Although the solar panels themselves are not typically a fire hazard, electrical components like inverters and batterises that store the electricity can pose a risk. Electrical malfunctions or faults can lead to fires, especially in poorly maintained systems in an event of a severe earthquake, and thus pose a longterm risk for the local ecosystem.

Overall, the mitigation of risks associated with utility-scale solar power plants involves a combination of technological advancements, sustainable practices, regulatory adherence, and ongoing monitoring and maintenance.

Oil Power

Oil-fired power plants can pose significant risks to society, people, and ecosystems in the event of a severe earthquake.

Oil Spills & Fires

One of the most immediate dangers is the risk of oil spills and fires. The shaking during an earthquake can rupture storage tanks and pipelines, leading to the release of large quantities of oil. Spilled oil can catch fire, causing explosions and further environmental damage.

Air Quality Polution

Oil fires and releases can result in the release of toxic fumes and particulate matter into the air. This can lead to poor air quality, posing health risks to nearby communities. People exposed to these pollutants may experience respiratory issues and other health problems.

Water Pollution

Spilled oil can contaminate nearby water bodies, including rivers, lakes, and groundwater. This can harm aquatic ecosystems, killing fish and other wildlife, and disrupting the food chain. Drinking water supplies may also be compromised, impacting human health.

Soil Contamination

Oil spills can saturate the soil, making it less fertile and potentially rendering it unusable for agriculture. Soil contamination can persist for years, affecting local food production.

Long-Term Environmental Damage

The environmental damage caused by oil spills and fires can persist long after the earthquake event. Cleanup efforts can be costly and challenging, and ecosystems may take years or even decades to recover fully.

To mitigate these risks, most modern oil-fired power plants follow strict regulations, safety measures, and extensive emergency response plans are in place for oil power plants located in seismically active regions. This includes robust containment systems, automatic shutdown mechanisms, and well-trained response teams.

Biomass Power

Biomass power plants, which generate electricity by burning organic materials like wood, agricultural residues, or waste, can pose certain risks during earthquakes. While biomass power plants are generally considered less hazardous than some other types of power generation facilities, yet there are still potential risks to be aware of.

Fire Risk

One of the primary risks associated with biomass power plants during earthquakes is the potential for fires. The shaking during an earthquake can damage electrical systems, equipment, and fuel storage, which may lead to electrical faults and fires.

Fuel Handling

Earthquakes can disrupt the fuel handling systems in a biomass plant, potentially causing spills or accidents related to the storage and transportation of biomass feedstock.

It's important to note that the specific risks associated with biomass power plants can vary based on factors such as plant size, location, and design. The biomass power industry prioritizes safety and works closely with regulatory authorities to ensure that biomass energy is generated with minimal risk to people and the environment, even in earthquake-prone regions.
