A magnitude-6.2 earthquake struck off the coast of Ecuador on Wednesday, the Pacific Tsunami Warning Center said, just days after a major quake hit the country.
The quake was centred 70km (44 miles) west-southwest of Esmeraldas at a shallow depth of 10 km, it said, not far from the epicentre of Saturday’s 7.8 magnitude quake.
Reuters witnesses in the zone said two strong tremors of about 30 seconds each were felt, waking people up and sending them racing them into the street.
It was not felt in the highland capital of Quito.
There was no immediate word from authorities on the impact of Wednesday’s quake.
Nearly 500 people died in the powerful 7.8-magnitude quake that struck Ecuador’s Pacific coast in a zone popular with tourists on April 16.
Authorities warned on Tuesday that 1,700 people were still missing as anger gripped families of victims trapped in the rubble.
“We have 2,000 people listed that are being looked for but we have so far found 300,” deputy interior minister Diego Fuentes told reporters in the capital Quito.
Some 4,605 people were injured, according to the latest government figures.
Hundreds of emergency workers from Colombia, Mexico, El Salvador, Spain and other countries were helping overwhelmed Ecuadorian officials involved in rescue operations.
Thousands of people have been left homeless by the April 16 earthquake and are prey to disease-bearing mosquitoes and dirty drinking water.
