Rock Friction Research Reframes Earthquake Mechanics

Scientists are studying how rock bonds break to understand earthquakes better. This new research affects how we predict and prepare for seismic events.

New research shows that the breaking of bonds between rocks, not just rubbing, is key to how earthquakes start. This is a new way to look at fault lines.

Using seismic noise and Horizontal-to-Vertical Spectral Ratios, Ávila-Barrientos et al. find a great dispersion of VS30 results in Baja California, Mexico, consistent with the heterogeneities between The Mexicali Valley and the Peninsular Ranges:

Do large surface creep events link to deeper earthquakes?

Huang et al.'s research on the Calaveras Fault suggests that structural controls are more important than surface creep transients in driving seismicity.

What causes onshore faults to slip in subduction zones?

Well, it turns out that the commonly held reason does not apply to the faults located in northern Cascadia.

Read Harrichhausen et al. to find out why: https://seismica.library.mcgill.ca/article/view/1177
