Nepal has been hit by a powerful earthquake, measuring a terrifying 7.9 in magnitude. The earthquake originated between Kathmandu and Pokhara. The tremors were so powerful that they were felt as far as Delhi and the other northern cities that lie in Nepal’s vicinity.Thousands of people are believed to be trapped and initial estimates point out that at least two people have been killed so far and the number is expected to climb considering the magnitude of the earthquake. Sadly the catastrophe also mulled down a 19th century nine storey tall tower in Kathmandu called Dharahara tower.

Earthquakes happen when two blocks of earth overlap on each other and slip past. The surface where the slip or the overlapping happens is referred to as fault plane. The edges of the tectonic plates are rough and the chances are that it gets stuck sometimes while the plate keeps on moving there comes a point wherein the plate has moved far enough to make the edges slide on one of the faults which becomes the epicenter of the earthquake.

The meteorological department no longer relies on the Richter scale for measuring the earthquake but they instead measure it by the size of the earthquake’s source at the epicenter. Seismographs are used by scientists to calculate an earthquakes time, location and magnitude. It records a zigzag trail on the paper which is nothing but a calculated magnification of the earth’s rumblings. Also Read - Facebook connecting over 7 million people in Nepal
According to magnitudes, earthquakes are classified into several categories. Quake measuring 3.0-3.9 is referred to as a minor earthquake, 4.0-4.9 is classified as Light earthquake, 5.0-5.9 are put under Moderate earthquake, 6.0-6.9 is referred to as Strong earthquake that can cause damage, 7.0-7.9 magnitude is a major earthquake capable causing a catastrophe and if the magnitude is greater than 8.0, it is capable of completely destroying everything.
