Seismicity variations associated with aseismic transients in Guerrero , Mexico , 1995 – 2006
Primarily aseismic deformation transients in subduction zones, sometimes associated with tremors and low-frequency earthquakes, are a newly recognized mode of deformation. Stressing in the up-dip seismogenic zone is increased episodically due to down-dip transient slips, and each eventmaymake itmore prone to failure in a large thrust earthquake. It is important for seismic hazard assessment to ...
متن کاملTwo successive slow slip events evidenced in 2009–2010 by a dense GPS network in Guerrero, Mexico
[1] A large slow slip event (SSE) had been expected for the Guerrero gap for 2010. It was actually observed with an onset in July 2009. Comparison with the preceding large SSEs, which occurred in 2002 and 2006, highlights both persistent characteristics of the Guerrero SSEs (e.g. the localization of slip in the seismogenic part of the subduction interface), and also particularities of the 2009/...
متن کاملInterplate coupling and a recent aseismic slow slip event in the Guerrero seismic gap of the Mexican subduction zone, as deduced from GPS data inversion using a Bayesian information criterion
A large-scale slow slip event with a magnitude equivalent to Mw = 7.4 has been observed at seven continuous GPS stations located in the Guerrero–Oaxaca region, southern Mexico, for several months from late 2001 to middle 2002 [Geophys. Res. Lett. (2003) 30: doi: 10.1029/2003GL017219]. We re-analyzed the GPS time series data to estimate the displacements associated with the slow slip event and a...
متن کاملFirst results from a dense semi-continuous GPS deployment during the September 2005 northern Cascadia slow slip event
In August of 2005, we deployed 29 GPS stations in the Olympic Peninsula with the goal of recording crustal motion associated with a slow slip event on the Cascadia subduction interface. This is the first semi-continuous GPS network established with the aim of providing a high resolution image of crustal motion associated with a slow slip event. We recorded data during the period from August 2 t...
متن کاملSeismic evidence of nonlinear crustal deformation during a large slow slip event in Mexico
Repeated cross-correlations of ambient seismic noise indicate a long-term seismic velocity change associated with the 2006 M7.5 slow-slip event (SSE) in the Guerrero region, Mexico. Because the SSE does not radiate seismic waves, the measured velocity change cannot be associated with the response of superficial soil layers to strong shaking as observed for regular earthquakes. The perturbation ...
