GPS stations in Chiapas are thus located at large distance from the shallow megathrust, unlike along Oaxaca where the offshore distance to the trench is small. The 2017 Chiapas earthquake struck the southern coast of Mexico on 7 September 2017 at 11:49 p.m. CDT (8 Sept. 04:49 UTC). Two major earthquakes in the same country within two weeks of each other may sound rare, but it’s not a surprise in such a seismically active region. Rather than being a plate boundary thrust event to fill the seismic gap, its faulting mechanism and depth indicate an intraslab normal fault rupture. Rescuers searched for survivors through the night after Tuesday's powerful earthquake shook Mexico City and surrounding states, killing scores … The earthquake measured 8.1 on the moment magnitude scale and a maximum Mercalli intensity of IX (Violent) and occurred near the state of Chiapas, approximately 87 kilometers (54 mi) south of Pijijiapan in the Gulf of Tehuantepec. We thank G. Hayes, an anomalous reviewer, and the Editor A. V. Newman for their constructive reviews. Just days later, a 7.1-magnitude earthquake shook Mexico City on September 19, 2017, toppling structures and prompting evacuations across Mexico’s capital. and Chemical Oceanography, Physical Our staff are on standby to respond with aid where it will be most needed,” she said. While the depth extent is not precisely resolved by our data, the rupture appears to extend from ~30 to 70 km, sufficient to locally detach the lithosphere. Guided by the faulting geometry from the W phase inversion, our relocated hypocenter, and the kinematic constraints from the backprojection, we invert for finite‐fault rupture models using teleseismic broadband P wave displacements and SH wave ground velocities (Figure 3) using linear least squares inversion based on Hartzell and Heaton (1983) and Kikuchi and Kanamori (1992), as updated by Ye et al. However, the lack of historic large megathrust ruptures in the relatively narrow strip of megathrust slip deficit raises the possibility that either the coupling is very heterogeneous due to the bathymetric structure of the subducting ridge, reducing the size of ruptures in the region, or the buoyancy is such that the region is undergoing high‐stress creep rather than stick‐slip motion. MEXICO has been hit by a powerful earthquake. The large‐scale variation in dip of the slab may influence the stress state locally (Ponce et al., 1992), but the stress is dominated by downdip tension, consistent with the steeply dipping normal fault for the 2017 event. The 2017 Chiapas earthquake was a strong earthquake that hit Mexico and Guatemala on September 7, 2017. Use the link below to share a full-text version of this article with your friends and colleagues. (2016b), giving a relatively high moment‐scaled value of 2.38 × 10−5. Chiapas officials said that more than 400 houses had been destroyed and about 1,700 others damaged. The 7 September 2017 earthquake and its damage reached Guatemala and El Salvador. Mexican President Enrique Pena Nieto declared three days of national mourning Wednesday, Sept. 20, to honor the victims in what is now the country’s deadliest earthquake since 1985. Chris Huber, Heather Klinger, and Kristy J. O’Hara of World Vision’s staff in the U.S. contributed to this article. Along the stretch of the Middle American Trench offshore of southern Mexico from 94°W to 96°W, the Tehuantepec Ridge is subducting at ~7.5 cm/yr (Figure 1).
