An earthquake of magnitude 4.1 on the Richter scale struck 31 km South South-West (SSW) of Champhai, Mizoram at 08:02 am today, the National Center for Seismology said.

This comes after a light intensity earthquake of 3.7 magnitude hit Mizoram on Tuesday, the third quake to rock the northeastern state in three consecutive days.

Two earthquakes struck Mizoram on Sunday and Monday, causing damage to houses and cracks on roads at several places and prompting the government to sound a rain and landslide alert.

A 5.1-magnitude tremor rocked Saitaul district at 4:16 pm on Sunday, followed by a 5.3-magnitude quake in Champhai district at 4.10 am on Monday. No casualties have been reported.

Several houses and buildings in Champhai, including two churches in Zokhawthar, have been damaged in the quake, an official said, adding that the tremors caused cracks on highways and roads at several places.
