We investigated stress change parameters for significant earthquakes globally. We propose an alternative new graphical method to analyze the variations between initial and final stresses compared to frictional stress during rupture.

it is enlightening to view the way aftershocks (in red) interact with background seismicity as outlined in a subduction zone. This case is the September 8th 2017 Tehuantepec earthquake (M8.2).

The facade of the National Library at UNAM campus is not only beautiful, but a tribute to the variety of colorful rocks which can be found in our country. Thanks to great artists like Juan O'Gorman.

Charles Richter & Beno Gutenberg developed the first magnitude scale in the 1930’s to quantify earthquakes by comparing the size (amplitude) of seismic waves plotted against distance (as calculated from S-P arrival times).

Following Trump's first term in office, the number of academic papers published by American authors on Earth science topics hit a 20-year low.

Research doesn't happen for free, and when governments curtail funding for certain research areas, it has consequences.

It's good that US has made seismic data publicly available. It would be even better to open (at least some) other data as well. Better still would be to have CTBTO involved. Or maybe open data from US IMS radionuclide stations. www.energy.gov/nnsa/article...
