Eight low-intensity earthquakes in the range of 2.2 to 3.6 magnitude were recorded in Palghar district of Maharashtra within four hours early on Friday, officials said.
The tremors were felt in Dahanu and Talasari tehsils of the district and no loss of life was reported so far, they said.
"An earthquake of 3.5 magnitude was recorded at 3.29 am, which was followed by 3.5 and 3.6 magnitude quakes at 3.57 am and 7.6 am respectively," chief of the District Disaster Control Cell Vivekanand Kadam said.

These two tehsils have been experiencing low-intensity earthquakes over the last few days. During the intervening night of Friday and Saturday last week, four such quakes had been recorded. One of them was of 4.0 magnitude, officials said.
Mittal said that in view of the series of tremors experience of late, big tents have been set up on open grounds in the villages of these two tehsils so that local residents can move in there if they feel unsafe in their houses.

According to Mittal, disaster coordination committees have been formed at the village level and the civil defence staff has been asked to remain prepared for assistance.
