Quake Swarm Continues

An earthquake swarm that may be connected with increased activity of Volcan Pacaya continues to rattle Guatemala City and surrounding areas.

There have been many quakes in the 2.0 to 3.5 range. On April 4th more than 600 microseisms were recorded.

The most recent stronger quake occurred three hours ago at 14:50:10.1 local time. It was a mag 4.5, with epicenter 27 km from the seismological station in Guatemala City. The quake was felt in Guatemala City, Retalhuleu, Escuintla, Sacatepequez, and Santa Rosa.

Similar swarms have occurred in Nov-Dec 1981, Jan-Mar 1982, Apr-May 1983, Jan 1984, Aug-Dec 1986, Feb-Mar 1987 and in July of 1999.

This swarm is not necessarily a cause for alarm but people should be aware. Now would be a good time to check your earthquake preparedness supplies.
