KPCC Staff and Monica Luhar, Southern California Public Radio, April 18, 2014

The USGS reported a magnitude-7.2 earthquake that struck southern Mexico Friday.

The quake was centered northwest of the Pacific resort of Acapulco. 

There were no immediate reports of casualties and damage, according to the Associated Press. USGS downgraded the quake’s magnitude from a 7.5 to a magnitude-7.2 quake, the AP reported. 

In 1985, a powerful magnitude-8.1 earthquake shook Mexico City, killing over 10,000 people, according to the LA Times.

The USGS has confirmed that there have been no significant earthquakes within the Guerrero Seismic Gap since 1911. USGS writes: 

The April 2014 earthquake occurred within the “Guerrero Seismic Gap” – an approximately 200 km long segment of the Cocos-North America plate boundary identified to have experienced no significant earthquakes since 1911 (M 7.6). The plate interface in this region is known to be locked, with an earthquake of M 8.1-8.4 thought possible should the entire gap rupture in a single event.

USGS has referred people to a variety of resources for the most up-to-date information:

  • USGS Prompt Assessment of Global Earthquakes for Response (PAGER) - Used for estimates of casualties and damage caused by worldwide earthquakes.
  • Tsunami watches, warning and advisories through the National Oceanic and Atmospheric Administration (NOAA) website. 

USGS is also urging people who have felt the earthquake to report their experiences here.
