On December 31, 2021 13:59:35 an earthquake with magnitude of 4.3 on the richter scale hit 35 km NW of Villa Mercedes, Argentina. The earthquake originated at a depth of approximately 9.41 kilometers below the Earth's surface on longitude -65.735° and latitude -33.459°. According to documented reports 5 people felt the earth quake, No tsunami was triggered due to the earthquake.

Magnitude & Depth

The earthquake that appeared on December 31, 2021 13:59:35 had a magnitude of 4.3 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 Cities and Towns

The nearest significant population center is Villa Mercedes in San Luis, Argentina, located 35 kilometers or 21 miles → E of the earthquake's epicenter.

Power Plants & Risks During Earthquakes

We found 1 types of power plants in the vecinity of the magnitude 4.3 earthquake that struck 35 km NW of Villa Mercedes, Argentina on December 31, 2021 13:59:35. These types were 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.

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.
