Last Updated: 2019-01-10 17:18:40

On October 28, 2018 09:03:41 an earthquake with magnitude of 4.2 on the richter scale hit 1 km SSE of Akhaldaba, Georgia. The earthquake originated at a depth of approximately 10.97 kilometers below the Earth's surface on longitude 43.496° and latitude 41.917°. According to documented reports people felt the earth quake, No tsunami was triggered due to the earthquake.

Magnitude & Depth

The earthquake that appeared on October 28, 2018 09:03:41 had a magnitude of 4.2 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.

Power Plants & Risks During Earthquakes

We found 1 types of power plants in the vecinity of the magnitude 4.2 earthquake that struck 1 km SSE of Akhaldaba, Georgia on October 28, 2018 09:03:41. These types were Hydro 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 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.


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.
