On June 17, 2020 15:51:44 an earthquake with magnitude of 3.0 on the richter scale hit 5 km NNW of Dubrava, Croatia. The earthquake originated at a depth of approximately 10.0 kilometers below the Earth's surface on longitude 16.035° and latitude 45.883°. According to documented reports 3 people felt the earth quake, No tsunami was triggered due to the earthquake.

Magnitude & Depth

The earthquake that appeared on June 17, 2020 15:51:44 had a magnitude of 3.0 on the richter scale. Which is considered to be a minor earthquake and is often felt but causes little to no damage.

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.

Nearby Power Plants

We found a total 11 utility-scale power plants in the vecinity of the earthquakes epicenter. The closest being Zagreb El-To CHP Power Plant Croatia Gas power plant, located 10 kilometers (6 miles) ↓ S from the epicenter.

Power Plants & Risks During Earthquakes

We found 4 types of power plants in the vecinity of the magnitude 3.0 earthquake that struck 5 km NNW of Dubrava, Croatia on June 17, 2020 15:51:44. These types were Hydro power plants, Nuclear power plants, Gas power plants, Oil 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.

Hydropower

Hydropower plants are generally considered as safe in many aspects, but when it comes to severe earthquakes they pose a substantial risk that can manifest in the form of dam faliours, landslides and grave impacts on surrounding ecosystems.

Dam Failure

The most significant risk is the potential failure of the dam that holds the water reservoir. Severe ground shaking can damage or breach the dam, leading to downstream flooding and as a result endangering people and wildlife living downstream. Such an event can also have severe impact on key infrastructure that cascades through society.

Landslides

Earthquakes can trigger landslides in the areas surrounding hydropower plants, potentially damaging infrastructure and causing harm to nearby communities.

Damage to Aquatic Ecosystems

Both landslide and dam failures can have a severe impact on upstream and downstream aquatic wildlife, ecosystem and groundwater, resulting in longterm risks for people and industires living and operating in areas near the water supply.

To mitigate these risks, engineering and construction standards for hydropower plants often include earthquake-resistant designs. These designs incorporate measures such as flexible foundations, strengthened dam structures, and advanced monitoring systems to detect early signs of stress. Additionally, emergency plans and evacuation procedures should be in place to protect personnel and downstream communities in the event of a severe earthquake.

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.

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.
