A strong earthquake has struck Ecuador's northwest coast.
There are no immediate reports of damage or injuries from the quake, which the U.S. Geological Survey says had a magnitude of 6.4. No tsunami warning has been issued.
The earthquake was centered near the town of Esmeraldas at a relatively shallow depth of 35 kilometers.
Some slight shaking was reported in the capital, Quito, 150 kilometers away.
The Esmeraldas area was devastated by a powerful earthquake in April that killed several hundred people.
