The USA is to send a team of disaster experts to help Ecuador with relief efforts following Saturday's major earthquake, a USAID official said.
The official said a small support team would also work with the U.N.'s Disaster Assessment and Coordination (UNDAC) team, which is helping Ecuador coordinate international rescue efforts.
The team will help with damage assessments and identifying humanitarian needs, the official added.
At least 413 people have died after the 7.8 quake and thousands are injured.
Rescuers in Ecuador pulled out three survivors from the rubble of a flattened shopping centre, more than 32 hours after a major earthquake.
An earthquake has hit Ecuador's northwestern coast, with hundreds injured, and dozens dead. Here's what we know.
The quake has caused "considerable damage" near the epicenter as well as in the largest city of Guayaquil.
