Quake rattles Central America...

earlier this morning and it's a big one, M7.1 according to the USGS. The epicenter is located offshore of Belize and Honduras, and minor damage has been reported. Click on the seismogram recorded in the EWU Department of Geology for an enlarged view. Note the sustained surface wave that lasts at least an hour.

I've done quite a bit of work in cave systems in this region and have observed large quantities of broken speleothems littering the floor of some chambers, speculating that the damage was the result of seismic jolts.

UPDATE: More news.

UPDATED UPDATE: Nice shaded relief map showing topography, faults and epicenter.
