Aizawl: An earthquake measuring 4.2 on the Richter scale hit east Mizoram’s Champhai district on Friday afternoon, the ninth quake to rock the state in the last one month, officials said.

According to National Centre for Seismology, the earthquake occurred at 3:56 pm and the epicentre was 33 km south-south-southwest of Champhai.

The depth of the earthquake was 10 km, it said.

Champhai district deputy commissioner Maria CT Zuali told EastMojo that tremor was felt in several villages, including Dungtlang, Farkawn, Samthang, Vaphai, Khuangthing and Zokhawthar on the Mizoram-Myanmar border.

No casualty and damage have been reported till Friday evening, she said.

However, the district administration and disaster management and rehabilitation department are assessing the quantum of damage and the final report is yet to come.

At least nine earthquakes hit several parts of Mizoram with Champhai district being the hardest since June 18.

So far, earthquakes have occurred in at least four districts- Champhai, Saitual, Serchhip and Siaha. The tremors ranged from 4.2 to 5.5 on the Richter scale.

Meanwhile, a preliminary study showed that Mizoram’s earthquake zone is caught between two geological faults- Churachandpur Moa fault and Mat fault, and several minor faults between these two major faults have caused frequent earthquakes in the state.

Earlier on July 10, chief minister Zoramthanga had asked the Centre to send expert seismologists or geo-physicists from Geological Survey of India (GSI) to assess the ground situation and exact cause of the earthquake.

He urged Union Minister of Mines Pralhad Joshi to conduct district-wise microseismic zonation covering Mizoram by the GSI and also to determine the feasibility of installing earthquake observation centres with real time seismic telemetry in the eastern part of the state for earthquake disaster preparedness.
