Seismologists to study Trinidad-area earthquakes

TRINIDAD, Colo. - A research team from the U.S. Geological Survey plans to visit the Las Animas County area around Trinidad to study a recent series of minor earthquakes.

According to KRDO-TV, the area had three earthquakes Wednesday and four more this month. The strongest was a magnitude of 3.6. There have been no reports of injury or damage from the quakes.

Justin Rubinstein of the USGS says five of the quakes were at least a magnitude of 2.5 and need to be studied. He says the average number of quakes above magnitude 3 in the area has risen from twice a year to eight a year since August 2001.

Rubenstein says the majority of quakes appear to be related to deep injection of large volumes of wastewater from drilling.
