Question

information about NEPAL earthquakes

Answer 1

The April 2015 Nepal earthquake (also known as the Gorkha earthquake)killed nearly 9,000 people and injured nearly 22,000. It occurred at 11:56 Nepal Standard Time on 25 April. Its epicenter was east of Gorkha District at Barpak, Gorkha, and its hypocenter was at a depth of approximately 8.2 km (5.1 mi).The ground motion recorded in the capital of Nepal was of low frequency which, along with its occurrence at an hour where many people in rural areas were working outdoors, decreased the loss of property and human life.

The earthquake triggered an avalanche on Mount Everest, killing 21, making 25 April 2015 the deadliest day on the mountain in history. The earthquake triggered another huge avalanche in the Langtang valley, where 250 people were reported missing.

Hundreds of thousands of Nepalese were made homeless with entire villages flattened, across many districts of the country. Centuries-old buildings were destroyed at UNESCO World Heritage Sites in the Kathmandu Valley, including some at the Kathmandu Durbar Square, the Patan Durbar Square, the Bhaktapur Durbar Square, the Changu Narayan Temple, the Boudhanath stupa and the Swayambhunath Stupa. Geophysicists and other experts had warned for decades that Nepal was vulnerable to a deadly earthquake, particularly because of its geology, urbanization, and architecture.

Continued aftershocks occurred throughout Nepal at the intervals of 15–20 minutes, with one shock reaching a magnitude of 6.7 on 26 April at 12:54:08 NST.The country also had a continued risk of landslides.

A major aftershock occurred on 12 May 2015 at 12:50 NST with a moment magnitude (Mw) of 7.3.The epicenter was near the Chinese border between the capital of Kathmandu and Mt. Everest.More than 200 people were killed and over 2,500 were injured by this aftershock and many were left homeless.

Answer 2

Nepal earthquake of 2015 , also called
Gorkha earthquake , severe earthquake that struck near the city of Kathmandu in central Nepal on April 25, 2015. About 9,000 people were killed, many thousands more were injured, and more than 600,000 structures in Kathmandu and other nearby towns were either damaged or destroyed. The earthquake was felt throughout central and eastern Nepal, much of the Ganges River plain in northern India, and northwestern Bangladesh , as well as in the southern parts of the Plateau of Tibet and western Bhutan .
The initial shock, which registered a moment magnitude of 7.8, struck shortly before noon local time (about 06:11 AM
Greenwich Mean Time). Its epicentre was about 21 miles (34 km) east-southeast of Lamjung and 48 miles (77 km) northwest of Kathmandu, and its focus was 9.3 miles (about 15 km) underground. Two large
aftershocks, with magnitudes 6.6 and 6.7, shook the region within one hour of the main quake, and several dozen smaller aftershocks occurred in the region during the succeeding days. On May 12 a magnitude-7.3 aftershock struck some 76 km (47 miles) east-northeast of Kathmandu, killing more than 100 people and injuring nearly 1,900.
The earthquake and its aftershocks were the result of thrust faulting (i.e., compression-driven fracturing) in the Indus-Yarlung suture zone, a thin east-west region spanning roughly the length of the
Himalayan ranges. The earthquake relieved compressional pressure between the Eurasian tectonic plate and the Indian section of the Indo-Australian Plate, which subducts the Eurasian Plate. Subduction in the Himalayas occurs at an average rate of 1.6–2 inches (4–5 cm) annually. Such tectonic activity adds more than 0.4 inch (1 cm) to the height of the Himalayan mountains every year.
The Himalayan region is one of the most seismically active in the world, but large earthquakes have occurred there infrequently. Before the 2015 temblor, the most recent large earthquake (that is, magnitude 6.0 or above) took place in 1988. That magnitude-6.9 event resulted in the deaths of 1,500 people. A magnitude-8.0 earthquake in 1934, however, killed approximately 10,600 people.
Initial reports of casualties following the early-morning earthquake put the death toll in the hundreds, but, as the day wore on, reports had the total number of fatalities surpassing 1,000 and nearing 1,900 by the end of the day. Within two weeks after the main quake occurred, rescue teams had reached all the remote villages in the earthquake zone, and a more-accurate picture of the earthquake’s human cost emerged. The deaths of approximately 9,000 people (which included fatalities in nearby parts of India, China , and Bangladesh) were confirmed, with nearly 16,800 injured and some 2.8 million people displaced by the earthquake. One United Nations (UN) report mentioned that more than eight million people (more than one-fourth of Nepal’s population) were affected by the event and its aftermath.
