Ecuador's Geophysics Institute says 230 aftershocks had hit as of last night, ranging in magnitude from 3.5 to 6.1 and striking at shallow depths.
The institute also sent out a steady stream of tweets this morning each time a new aftershock was registered. Most were happening in the Pacific Ocean near the hard-hit coastal cities of Pedernales and Manta.
Ecuador's president, Rafael Correa, has warned the death toll could rise significantly from Saturday's quake, which also injured more than 2,500 people.
