Slab2 model for the Middle America slab in Mexico
Sources/Usage: Public Domain.
Slab2 model for the Middle America slab in Mexico. Main panel shows a cross-section of Slab2 (blue dot-dashed) vs Slab1.0 in this region (red dashed). The Slab2 model shows a more northeasterly extent to the flat slab than is imaged by earthquake data and focal mechanisms (circles and beachball symbols). Earthquakes and focal mechanisms are colored by depth, according to the scale used in the inset. The location and focal mechanism solution of the September 19, 2017, M7.1 intraplate earthquake near Mexico City is highlighted. The projection width of the cross-section is +/- 50 km.

This web application is used for generating a 3D slab model following the procedure of Hayes et al., 2018. If using models generated from this web application, please cite Hayes et al., 2018 and Haynie et al., 2020 (AGU abstract). Instructions for plotting the model results can be found in the Slab2 code documentation and GitHub repository.

To generate a slab model, please enter your email address, select a slab region (refer to the map on the right), choose if you would like to model the surface to the top of the slab or the center of the slab, and lastly choose the Slab2 database you would like to use for creating your model. Once submitted, the form will refresh and you will receive an email.

Slab2 - A Comprehensive Subduction Zone Geometry Model

Subduction zones are home to the most seismically active faults on the planet. The shallow megathrust interface of subduction zones host our largest earthquakes, and are the only faults capable of M9+ ruptures. Despite these facts, our knowledge of subduction zone geometry - which likely plays a key role in determining the spatial extent and ultimately the size of subduction zone earthquakes - is

Slab2, a comprehensive subduction zone geometry model

Subduction zones are home to the most seismically active faults on the planet. The shallow megathrust interfaces of subduction zones host our largest earthquakes and are likely the only faults capable of magnitude 9+ ruptures.
