Two small earthquakes occurred in Plainfield Tuesday morning, minutes after each other, according to Boston College’s Weston Observatory. The first was a 0.8-magnitude quake at 9:13 a.m., and the second was a 1.5-magnitude temblor at 9:18 a.m., the observatory said. Quakes with a magnitude under 2.0 are not usually felt by people, said John Ebel, director at the geophysical observatory. There have been about 60 micro-earthquakes in the same area since the beginning of the year, he said. “Most are not being heard or felt,” he said.
