An earthquake measuring 5.2 on the Richter scale was reported in western Assam on July 7, officials said.
The tremors were felt in Shillong and other parts of neighbouring Meghalaya and also in North Bengal.
According to the National Centre for Seismology (NCS), the tremors occurred at 8:46 am and the epicentre was near Goalpara in Assam. It occurred at a depth of 14 km from the surface, and was also felt in neighbouring Bangladesh.
As per the disaster management officials in Guwahati, there was no reports of any injury to anyone or damage to property and other assets.
Reports said that people in Goalpara and Garo Hills in Meghalaya ran out of their homes in panic.
Successive tremors in the mountainous Northeast states, especially in Assam, have made the authorities worry.
A powerful 6.4 magnitude quake had shaken several districts of Assam and adjoining Northeast states and Bhutan on April 28 causing damages to many buildings and other properties.
Seismologists consider the region as the sixth most earthquake-prone belt in the world. In 1950, an earthquake measuring 8.7 on the Richter scale had altered the course of the mighty Brahmaputra river, which passes by the Guwahati city.
