Stamford-based Americares has deployed a team of mental health experts to assist families in Puerto Rico displaced by recent earthquakes.

A 6.4-magnitude earthquake struck Puerto Rico's southwest coast on Tuesday, killing at least one person, toppling buildings and causing power outages across the island.

Tuesday's earthquake followed the 5.8-magnitude quake that hit Puerto Rico early Monday, collapsing homes in Guánica and heavily damaging dozens of buildings.

According to the U.S. Geological Survey, hundreds of small earthquakes have hit the island since Dec. 28, including at least 29 over magnitude 4.0.

Americares deployed an emergency response team from its office in San Juan to Guánica to assist families displaced by the earthquakes.

Americares says the team includes psychologists, a social worker and a counselor who will provide psychological first aid to children and adults temporarily staying in an emergency shelter.
