PLAINFIELD, Conn. (AP) A 2.2-magnitude earthquake has rattled eastern Connecticut again.

In what's becoming a daily seismic event, the Weston Observatory of Boston College said the earthquake occurred at about 4:40 a.m. Thursday near Plainfield, where previous earthquakes were recorded.

It says two minor earthquakes were recorded on Wednesday and another on Tuesday.

Several were recorded on Monday and last week, too.

The observatory says that while the greatest earthquake activity in the United States is in the west, earthquakes are ``quite common'' in many areas of the eastern United States, including New England.

Plainfield officials have invited Alan Kafka, director of the observatory, to an informational meeting at 6:30 p.m. Friday at the town's high school.
