“…The age of this event through OSL dating of quartz grains indicates that this earthquake and tsunami occurred between 1240 and 1370 AD (Supplementary Table S3). The earliest historical documents written in Spanish record earthquakes that occurred in the 15 th century 21 and the oldest historical tsunamigenic event recorded on the GS date to 1537 AD 22 . Thus, historical records do not, but our results using different proxies demonstrate that a large tsunamigenic earthquake occurred on the Guerrero coast between 1240 and 1370 AD.…”

Globally, the largest tsunamigenic earthquakes have occurred along subduction zones. The Mw>9 devasting events in Chile, Sumatra, and Japan struck in areas where no instrumental records reported similar events. The one-thousand kilometer-long Mexican subduction zone (MSZ), where the Rivera-Cocos plates subduct under the North American plate, has no records of events of such magnitude. Historical and geologic evidence suggests the occurrence of a Mw8.6 tsunamigenic earthquake in the MSZ. However, the Guerrero segment (GS) has not experienced a large event in over 100 years. Several hypotheses have been proposed to explain this, e.g., slow slip events (SSEs) and the rheology of this segment favoring slow slip over rapid slip. However, none of these hypotheses have been confirmed with evidence. Here, we show geologic evidence that reveals a ca. 2000-year history of large tsunamigenic earthquakes and demonstrate that a Mw>8 event occurred ca. AD 1300 in this segment of the MSZ, indicating a long and variable earthquake recurrence (> 700 years). This evidence prompts the assessment of earthquake and tsunami potential using long-term evidence combined with instrumental observations along the MSZ and other subduction zones.

“…Several large subduction earthquakes of Mw > 7 have occurred over the last century (Kostoglodov and Ponce, 1994). Hence, seismic movements within the Mexican Pacific are frequent and its coastline is vulnerable to seismic hazards (Ramírez-Herrera et al, 2016). Of the interactions described in section 1.1, the study area refers to the Mexican Southeast whose zone is characterized by having a 110 complex tectonic interaction and great potential to generate large earthquakes, see Fig.…”

Abstract. Although the seismic information from the subsoil is very important, in some areas of the world this is not available due to various factors, the main one being a seismically low area. It is important to say that the planet has been changing and many intraplate earthquakes have occurred in places never expected, spreading seismic waves to places where they were considered low seismicity. For example, on September 8, 2017 in Ciudad del Carmen, 500 km from the epicenter, the earthquake was felt causing damage to the facades of the buildings. Therefore, it is important to have the subsoil shear-waves velocities to subsequently generate a good analysis and structural seismic design. For this reason, in this study under the seismic approach an assessment of Ciudad del Carmen Campeche subsoil is presented. Active and passive Multichannel Analysis of Surface Waves and Refraction Microtremor technique to investigate seismically subsoil characteristics have been employed. Shear wave velocities were obtained up to a depth of 30 m with magnitudes of 172.45 m/s to 353.90 m/s. Based on the Vs30 values, the subsoil is seismically classified into D and E according to the criterion of the National Earthquake Hazards Reduction Program and International Building Code, turning out to be very vulnerable to high damage during the earthquake shaking. Furthermore, Ciudad del Carmen was regionalized into three types, where type I being a dense soil or averagely soft rock with Vs30 greater than 360 m/s, type II when the soil has an intermediate dynamic amplifications with Vs30 between 180 to 360 m/s, and type III correspond to a soil with large dynamic amplifications and Vs30 less than 180 m/s.
