Second earthquake of 4.1 magnitude hit north Bengal
Later, a mild earthquake of 4.1 magnitude hit north Bengal on Tuesday morning, as per the National Center for Seismology. The earthquake, the second to hit the region in less than 10 hours, occurred at 7.07am and the location was 64 km east of Siliguri, it said. The depth was 10 km, it added. There was no immediate report of any damage or losses, officials said. However, people came out of their homes in panic as the tremors were felt across the north Bengal districts of Jalpaiguri, Alipurduar and Darjeeling. The impact was also felt in parts of Sikkim.

Earthquakes hit North East India, government takes swift action
Prime Minister Narendra Modi is taking stock of the damage due to the earthquake. He is reportedly speaking to the chief ministers of all four affected states. The Prime Minister has already spoken to the CMs of Bihar, Assam, and Sikkim, news agency ANI quoted government sources as saying.
Bihar Chief Minister Nitish Kumar informed the prime minister that the state’s Disaster Management Department and district magistrates concerned have been put on alert, a communication issued by the CMO said.

“Generally, aftershocks do not occur following any quake below the magnitude of six. So, in this case, there is no possibility of aftershocks,” PTI quoted an NCS official as he explained the possibility of aftershocks following the earthquake.
High seismic activities around Himalayas
The Himalayas are prone to earthquakes and are known for high-seismic activity. In India, one of the most seismic hazard zones is North east part of India. This region has witnessed several major earthquakes causing large scale devastation. The main cause of this high seismicity in North East India is its unique placement of tectonic plates and their interactions.
