QUITO - A new aftershock measuring 6.0 on the Richter scale shook Ecuador today in the same area where the 7.8 magnitude earthquake struck on Apr 16, which killed at least 580 people.
Ecuador's Geophysics Institute (IG) of the National Polytechnic School noted that the aftershock occurred at a shallow depth of 10 kilometers and was located in the sea, about 60 kilometers west of Jama, one of the towns most affected by Saturday's earthquake.
The aftershock, which was initially measured at a magnitude of 6.3, was revised down to 6.0, a source from the Geophysical Institute told Efe.
The source said that so far there have been 657 aftershocks after the main shock hit Ecuador at 18.58 local time on Apr. 16. Its epicenter was located between the towns of Cojimies and Pedernales in the coastal province of Manabi.
The IG believes that the continuing aftershocks will continue for a week or more and explained that these earthquakes are results of the Nazca Plate subducting the continental South American Plate.
The Ecuadorian president Rafael Correa who is currently visiting the areas affected by the earthquake posted the aftershock on his twitter account from the city of Bahia de Caraquez.
"We are in Bahia. There are three aftershocks, two fairly strong. One has its epicenter near Jama and another with its epicenter near Canoa. Stay calm. Geophysical Institute says that this is normal and that around 10 aftershocks of that magnitude are expected. Cheer up!" wrote the president.
