Was the Nepal earthquake twice as big as we thought?

On April 25, Nepal was hit with the biggest earthquake in 80 years—but just how big was it?

Amidst the destruction, there was a spat on the issue between the US and China. The US Geological Survey (USGS), which monitors earthquakes worldwide, reported that the Nepal earthquake measured at a magnitude of 7.8. However, the China Earthquakes Network Center (CENC), which hopes to provide a similar service, measured the same earthquake at a magnitude of 8.1.

A difference of 0.3 in the magnitude of the seismic activity may not seem like much, but the apparently small differences in magnitudes of earthquakes reported by different agencies around the world are, in real-life, huge. Because if we are to believe the Chinese data, the Nepal earthquake may have been 2.8 times bigger than if we believe the US data.

This is because of how earthquakes are measured.

Death Toll From Nepal Earthquake Crosses 5,000 as Rescue Teams Begin to Arrive at Remote Villages

Rishi Khanal spent about 80 hours in a rubble-filled room with three dead bodies after the seven-story building he was in collapsed around him during Saturday’s massive earthquake in downtown Kathmandu. The 28-year-old was finally pulled out of the rubble on Tuesday, Reuters reports, by a Nepali-French rescue team combing the capital city for survivors.

“It seems he survived by sheer willpower,” said Akhilesh Shreshtha, a doctor who treated him, after it appeared that Khanal had no access to food or water for three days and escaped with nothing but a possible broken leg.

Khanal’s rescue was a heartening but rare story from the devastation in Nepal, where a 7.8-magnitude earthquake over the weekend killed more than 5,000 people. That toll is sure to rise significantly as rescue teams move away from Kathmandu, which they began to do early Wednesday, and reach devastated villages near the quake’s epicenter.
