What caused the Nepal earthquake? Magnitude of Nepal earthquake 2015 which was 7.8 Magnitude was equal to the explosion of tens of atomic bombs. Facts about earthquakes causes in Nepal was the ancient tectonic plates crushes between Indian as well as Eurasian plates. The causes of Nepal earthquake 2015 was thrust fault which meant that the crushes of tectonic plates formed thrust fault where Indian plate pushed under Eurasian plate that also had formed the world’s highest mountain range of the Himalaya as well as the world’d highest mountain of Everest for more than 50 million years back.

For that time in the past, that Indian plate has continued pushing beneath that Eurasian plate with a pace of 45 millimeters or about 2 inches a year. Within 1931, there was a powerful earthquake in Nepal with a magnitude of 8+ that released built-up tension for past ages. That cracks line such as fault line under the Nepal’s city, Kathmandu, has been formed as cause for the large earthquake in Nepal and the effects on countries nearby that bordered with this region.

Under the Nepal main city, Kathmandu, there was earthquake fault as a result of seismic activity of the tectonic plates underneath. Therefore, the factor to Nepal earthquake was mainly due to the seismic processes under that region.

As it has been mentioned above, what caused the Nepal earthquake was two ancient tectonic plates that occurred along the thrust fault. The fact is that the earthquake occurred at a depth of just 15 kilometers under the ground. The focus of earthquake below 70 kilometers is considered to be short focus earthquake. That was shallow earthquake. With the power of 7.8 Magnitude, it has been categorized as powerful earthquake that lead to the deaths of Nepalese people living in low building structure.

Effects of Nepal Earthquake of the short focus earthquake brought bigger threats, greater earthquake effects and hazards towards areas around the epicenter of the earthquake such as Kathmandu as well as the India nation. As for the length and the width of the Kathmandu area, that town features a small areas of only 60 kilometers long and 120 kilometers wide in size of the small city.

 

Facts about Nepal Earthquake

How long did the Nepal earthquake last? Kathmandu after hit by the earthquake has been moved to the south about 3 meters within less than a second. Eurasian plate is a combined name for Europe and Asian which means the tectonic plate under European and Asian continent. The 2015 Nepal earthquake could happen as a result of the Indian plate pushed under the Eurasian plate to the north. As well, Eurasian plate pushed above the Indian plate to the south was significantly able to move the Nepal territory such as Kathmandu to the south. The earthquake that was triggered by tectonic plates crushes forming thrust fault under Kathmandu brought avalanches on Everest Mountain, the highest mountain in the world. How many people died in the Nepal earthquake? There was over 9000 casualties caused by the Nepal earthquake.

The scientific study has also shown that what caused the Nepal earthquake was accumulated tectonic tension on the plate edge for 700 years that was postponed under the Nepal nation. Therefore, the logic reason for the re-occurrence of the earthquake was part of the tension that was kept on the plate boundaries within decades or even in centuries. The Nepal earthquake 2015 was the second biggest quake in the region since 80 years ago which was the 1934 earthquake occurred in magnitude of 8.2. Another big earthquake also occurred in the region which was Kashmir earthquake 2005 occurred in magnitude of 7.6 in Richter scale that killed over 80.000 individuals in that city.
