A moderate quake, measuring 4.1 on the Richter scale, occurred in Assam's main city of Guwahati and adjoining areas on Saturday but no loss of life and damage to property has been reported so far.
The National Centre for Seismology (NCS) said that the tremors were also felt in Kamrup (Metro) district, where Guwahati city falls, and adjoining areas.
The quake occurred at a depth of 10 km from the surface.
Disaster Management officials said that there have been no reports of any injury or damage to property so far.
Guwahati is also the main commercial hub of the entire northeastern region. Successive earthquakes in the northeastern states, especially Assam, Mizoram and Manipur, have the authorities worried.
A 6.4 magnitude quake had shaken Assam and parts of the northeast region on April 28 damaging buildings, roads and other assets.
Seismologists consider the northeast region as the sixth most earthquake-prone belt in the world.
Similarly, an earthquake, measuring 4.6 on the Richter Scale, hit Jalore in the early hours of Saturday, according to National Centre for Seismology.
Tremors of the quake, which occurred at 2.26 a.m., were felt in several villages in Pali, Sirohi, Jalore and Jodhpur districts for 7 to 12 seconds. Panic-stricken people rushed out of their homes.
The quake was epicentered in Jalore, officials confirmed.
Research is required to study the geological movement in the Aravalli belt, the officials said, adding that the rubbing of tectonic plates in the fault line adjoining Gujarat led to the quake.
