QUITO: A 5.7-magnitude earthquake followed by 37 aftershocks rattled Ecuador’s Pacific coast before dawn Monday, causing three deaths and heavy damage to hotels and homes in resort towns, officials said. The northwestern province of Esmeraldas — hit hard by a devastating temblor in April — bore the brunt of the new quake, too. Three people died and 47 were injured as a result of the quake, according to disaster management agency SGR. At least 700 families had to leave their homes. The dead all suffered from heart attacks, said President Rafael Correa, who rushed to Esmeraldas.
