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.
Correa says Ecuador will overcome the tragedy. He says "the Ecuadorean spirit knows how to move forward, and will know how to overcome these very difficult moments."
