Geodisasters: Earthquake

Abstract

Geodisasters is a natural disaster caused by the process of geological change.to bring the earth's surface to equilibrium. For example : landslides, fissures, sinkhole and earthquakes. Most of the geodisasters will occur suddenly and are difficult to predict in advance. Extreme cases can cause loss of life and property. It affects the overall economic and social development of the country.

Earthquake is a natural disaster caused by the vibration of the earth's surface due to the sudden release of the energy stored within the earth to reduce stress and stabilize the balance of the earth's crust. The latest severe earthquake occurred on March 28, 2025 around 13:25 hours..An earthquake of magnitude 7.7 Richter occurred which is centered in the Sakai region of Myanmar. This makes the building of the new Audit Office which is tall. 33 floors and under construction was collapsed. As a result, at least 95 people were killed,1 person was missing and only 9 were survived. It also caused damage to many high-rise buildings in Bangkok. Earthquakes are caused by two main reasons: 1) cause by human actions, such as: atomic bomb test, dam water retention and mining Explosion  2) Spontaneous occurrence from nature due to the movement of tectonic plates.

Thailand is in a position that is considered relatively earthquake-free. Most of them are small to moderate earthquakes. The earthquake in Thailand is part of the Eurasian tectonic plate It was found that there was a group of active fault in the northern region and western region of Thailand, It continues to the east of Myanmar. Currently, there are still 16  fault groups  in motion.The northern and western regions are more vulnerable to severe and very severe earthquake disasters than the central region, eastern region and northeastern regions. Provinces at risk of severe earthquake disasters include Chiang Rai, Chiang Mai, Lampang, Phrae, Mae Hong Son, Tak and Kanchanaburi. Guidelines for earthquake prevention and mitigation preparation and practice are required.
