Seismogenic zone structure of the southern Middle America Trench, Costa Rica [PDF]

Journal of Geophysical Research, 2003
The shallow seismogenic portion of subduction zones generates damaging large and great earthquakes. This study provides structural constraints on the seismogenic zone of the Middle America Trench offshore central Costa Rica and insights into the physical and mechanical characteristics controlling seismogenesis. We have located ∼300 events that occurred

Thermal structure and megathrust seismogenic potential of the Makran subduction zone [PDF]

Geophysical Research Letters, 2013
The Makran subduction zone experienced a tsunamigenic Mw 8.1 earthquake in 1945 and recent, smaller earthquakes also suggest seismicity on the megathrust; however, its historical record is limited and hazard potential enigmatic. We have developed a 2‐D thermal model of the subduction zone.

Using Resistivity Structure to Study the Seismogenic Mechanism of the 2021 Luxian Ms6.0 Earthquakes

Remote Sensing
Over the past few years, there has been a noticeable change in the occurrence of seismic disasters in Sichuan, China. The focus has shifted from Western Sichuan to the previously more stable Southeastern Sichuan. The recent Ms6.0 earthquake in Luxian, Southeastern Sichuan, on 16 September 2021, has once again captured the interest of scholars, who are ...

InSAR coseismic deformation and seismogenic structure of the 2023 MW6.9 Tajikistan earthquake

Geodesy and Geodynamics
An earthquake of magnitude 6.9 occurred in Tajikistan on February 23, 2023. Studying this earthquake is the key to understanding the seismogenic structure of this area. The slip distribution of the MW6.9 earthquake was inverted using InSAR technology and

Discussion of the seismogenic structure of the 1901 M 6¾ Nyemo earthquake

Dizhi lixue xuebao, 2021
According to historical records, an M 6¾ earthquake occurred in Nyemo, Tibet on April 21, 1901 without any reports on its seismogenic structure yet. To sort out its seismogenic structure helps to understand the earthquake recurrence pattern of the Nyemo ...

The relationship between structure and seismogenic behaviour in subduction zones

, 2014
The largest earthquakes on Earth take place on the megathrusts of subduction zones, but the slip behavior of megathrusts is variable. This thesis considers why by conducting local, regional and global studies of the interrelationships between the structure and seismogenic behavior of subduction zones.
