Mizoram was rocked by an earthquake measuring 4.7 on the Richter scale on Friday evening, Dr H Lallenmawia, joint director of Geology and Mining, said.
Quoting the Seismological Observatory reading, Lallenmawia said that the epicentre of the quake was latitude degree 24.57 and longitude degree 94.5 (at the Indo-Myanmar border area).
Residents of Aizawl said that the earthquake of moderate intensity was felt in their homes for a few seconds at around 6.55 pm in the evening.
No casualty was reported.
Geologists said the density of soil in Mizoram is very thin, which helped reduce the impact of earthquakes.
"Earthquake of high intensity for a longer period of time can be extremely disastrous in view of the soil condition and also violation of building norms, especially in Aizawl," Lallemnawia said.
