Chile Earthquake – Aftershocks Update 2

Significant aftershocks continue to strike Chile Coast

Dozens of aftershocks measuring ≥ 5.0Mw have struck the Chilean coast following the 8.3Mw mainshock that struck at 22:54:33UTC on Wednesday.

The quakes have killed at least a dozen people, and forced more than a million people out of their homes. However, there were no reliable reports of the number of injuries or extent of property damage, as of posting.

The ensuing tsunami that followed the mainshock caused extensive flooding in multiple coastal towns including the port city of Coquimbo, which was hit by waves of up to 4.5 meters and sustained significant damage, officials told reporters.

The largest aftershocks, according to USGS/EHP, include:

Tsunami Information Statements issued by NOAA/NWS/West Coast and Alaska Tsunami Warning Center and PACIFIC TSUNAMI WARNING CENTER/NOAA/NWS said:

A strong earthquake has occurred, but a tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, or Alaska coast. NO tsunami warning, watch or advisory is in effect for these areas.

Based on the earthquake magnitude and historic tsunami records, a damaging tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, and Alaska coasts. At coastal locations which have experienced strong ground shaking, local tsunamis are possible due to underwater landslides.
