An earthquake of magnitude 3.7 on the Richter scale hit Assam’s Tezpur at 10:05 am on Friday. According to the National Centre for Seismology (NCS), the earthquake’s epicentre was 39 kilometres west of Tezpur and occurred at a depth of 10 kilometres. So far, no casualties or damage to property was reported.
Soon after the earthquake, another tremor was felt at 10:23 am of 3.9 magnitude in the Union Territory of Ladakh on Friday morning. The depth of the earthquake was 10 kilometres.
Earlier on Thursday night, an earthquake of 3.2 magnitude struck the Union Territory of Ladakh. The tremor was felt at 10:22 pm. So far, there is no report of any damage. The depth of the earthquake was recorded to be 10 kilometres.
An earthquake of 4.3 magnitude hit Rajasthan's Bikaner at 11:36 pm on Tuesday. Shockwaves were also felt in the adjoining areas of the state. The epicentre of the earthquake was 685 km west of Bikaner and it struck at a depth of 10 km. No damage to property or casualties were reported.
An interesting fact about earthquakes occurring frequently at 10 kilometres is because it is a "fixed depth". According to the United States Geological Survey (USGS), sometimes the data is too poor to compute a reliable death for an earthquake. So, in these cases, the depth is assigned to be 10 kilometres because in many areas around the world, depths tend to average 10 km or close to it.
The USGS explained: "f we made a histogram of the reliable depths in such an area, we'd expect to see a peak around 10 km. So 10 kilometres is a reasonable guess."
