Three successive earthquakes measuring 3.6 to 5.3 on the Richter scale hit eastern Mizoram’s Champhai district within an hour on Thursday evening.
However, there was no report of any damage or loss of property.
The India Meteorological Department (IMD) officials said the first quake of 5.3 magnitude hit at 5.37 p.m. followed by tremors of 3.6 and 4.1 magnitudes at 6.16 p.m and 6.47 p.m. respectively.
The epicentre of the quakes was 35 km southwest of Champai district headquarters.
With a population of 1.1 million, Mizoram, the second least populous state in the country, has recorded successive quakes since June 22, when a moderate earthquake, measuring 5.5 on the Richter Scale, shook the Champhai district and adjoining areas, damaging more than 31 structures, including roads and buildings.
Besides Champhai, a series of tremors have also hit Saitual and Serchhip districts since June 22.
Seismologists consider the mountainous northeast region as the sixth major earthquake-prone belt in the world.
