The earthquake was followed by a series of aftershocks in the area.
  • USGS PAGER estimates that concerning the main event, up to 93,000 people were exposed to very strong shaking, and up to 733,000 to strong shaking. According to last report of the Pacific Tsunami Warning Center, tsunami threat has passed and minor sea level fluctuations of up to 0.3 metres can continue for the next few hours in the coast of Mexico.
