Resumen

FRANCO, Sara Ivonne et al. Preliminary report of the April 13 2007 earthquake, Guerrero, Mexico. Bol. Soc. Geol. Mex [online]. 2007, vol.59, n.1, pp.71-81. ISSN 1405-3322.  http://dx.doi.org/10.18268/bsgm2007v59n1a6.

On april 13, 2007 at 05:42 (Universal Time) an earthquake, with magnitude Mw=5.8, occurred in the state of Guerrero, Mexico, near the Pacific Coast. The event was recorded in 27 stations that comprise the Broadband Seismic Network, managed by the National Seismological Service of Mexico. The source parameters show an interplate thrust earthquake with an almost vertical fault plane. The epicentral location lies within the Guerrero seismic gap. Nevertheless, the hypocentral depth of 30 km makes it difficult to associate this earthquake to a possible stress relaxation in this gap. The largest peak ground acceleration was recorded at CAIG, a broad-band station located less than 20 km from the epicenter. The attenuation curve suggests a very energetic earthquake in comparison with other Mexican interplate events.

Palabras llave : Guerrero gap; attenuation; focal mechanism; interplate earthquake.
