On April 25th, 2015, a devastating earthquake ravaged Nepal. It killed about 9000 people and injured a thousand others. More than 600,000 concrete buildings and other structures were damaged all across Nepal. The earthquake was so strong that the vibrations were felt as far as the Northern part of India and the North-western parts of Bangladesh including Western Bhutan and Southern parts of the Tibet plateau.
Here are a few more facts about the devastating earthquake:
The infrastructure of Nepal was very weak when the earthquake struck the Himalayan country. The majority of the houses and other structures were built without following a proper building code and also using low-quality construction materials. In 1994, the administration of Nepal tried to implement a building code following another earthquake; however, it turned out to be unenforceable. In majority of the cases, falling debris of the houses kills more people than the earthquake itself. And that’s why it is important to use good quality building material such as earthquake resistant TMT bars must be used to construct a house.
Earthquake resistant TMT bars have higher elongation as they have a soft ferrite-pearlite core and a tough exterior. These can withstand pressure (including seismic shaking, thus making it safe for being used in earthquake-prone zones. If you are looking for higher elongation TMT bars in West Bengal or Nepal, check the products from SRMB. For more details, visit https://www.srmbsteel.com/tmt-bars
The initial shock that struck the country was measured at 7.8 on the Richter scale. It struck shortly after noon, and its epicentre was about 34 kilometres East-Southeast of Lamjung in Nepal and was about 77 kilometres north-west of the capital city of Kathmandu. Within an hour of the initial shock, two shocks of magnitudes 6.6 and 6.7 shook the region. During the following days, the country experienced some smaller aftershocks.
The Nepal earthquake and the resulting aftershocks were caused by a thrust in the fault line in the Indus-Yarlung suture zone. This area lies in the East-West region and is near about the length of the Himalayan range. The earthquake is said to relieve the compressional pressure that developed between the Indian section of Indo-Australian plate and the Eurasian tectonic plate.
About 9,000 people were killed in Nepal alone, and more than 10,000 people were injured. When the earthquake struck Nepal, it resulted in an avalanche in the Mount Everest. 18 mountaineers died in their base camp in that avalanche. About 75 people in India were killed due to the vibrations, and 25 people in China lost their lives.
Shift in Earth’s surface
The Nepal earthquake was so strong that it resulted in a shift in the Earth’s surface. It is reported that the Earth’s surface shifted about 3 metres in 7,200 kilometres. A few parts of the capital city of Kathmandu is said to be lifted by about 3 feet vertically. This caused immense damage in Kathmandu.
Hopefully, these facts have helped you gain some insights into the damaging effects of the earthquake in Nepal.
