Effects of Near‐Fault Sedimentary Rocks and Damage on the 2019 Ridgecrest, CA Earthquake: A Rupture Impediment or a Ground Motion Booster?

Geophysical Research Letters
Observations of the 2019 magnitude 7.1 Ridgecrest, California, earthquake indicate a relatively slow rupture (∼2 km/s). The fault is surrounded by sedimentary rocks and low‐velocity damage zones, which can amplify ground motions but also slow down ...

Modeling fast and slow earthquakes at various scales

Proceedings of the Japan Academy, Series B, 2014
Earthquake sources represent dynamic rupture within rocky materials at depth and often can be modeled as propagating shear slip controlled by friction laws. These laws provide boundary conditions on fault planes embedded in elastic media. Recent developments in observation networks, laboratory experiments, and methods of data analysis have expanded our

Theoretical Constraints on Tidal Triggering of Slow Earthquakes

Journal of Geophysical Research: Solid Earth
Abstract Tidal stress is a globally acting perturbation driven primarily by the gravitational forces of the Moon and the Sun. Understanding how tidal stresses can trigger seismic events is essential for constraining tectonic environments that are sensitive to small stress perturbations.

Data assimilation for fault slip monitoring and short-term prediction of spatio-temporal evolution of slow slip events: application to the 2010 long-term slow slip event in the Bungo Channel, Japan

Earth, Planets and Space
Monitoring and predicting fault slip behaviors in subduction zones is essential for understanding earthquake cycles and assessing future earthquake potential. We developed a data assimilation method for fault slip monitoring and the short-term prediction

Review of transect of Christchurch CBD following 22 February 2011 earthquake

, 2012
Two days after the 22 February 2011 M6.3 earthquake in Christchurch, New Zealand, three of the authors conducted a transect of the central city, with the goal of deriving an estimate of building damage levels.

Similarities and Differences Between Natural and Simulated Slow Earthquakes

Geophysical Research Letters
We investigate similarities and differences between natural and simulated slow earthquakes using nonlinear dynamical system tools. We use spatio‐temporal slip potency rate data derived from Global Navigation Satellite System (GNSS) position time series ...

Comparative Analysis of Seismicity Across Three Depth‐Dependent Slip Regimes in the Japan Trench Subduction Zone

Geophysical Research Letters
Understanding the cause of spatial variations in seismicity is crucial for comprehending the physics governing earthquake activity. Off Iwate, in the northern Japan Trench subduction zone, the plate boundary can be divided into three distinct zones based

What do Haitians need after the earthquake? [PDF]

The earthquake that hit Haiti in the beginning of 2010 led to tremendous international solidarity in the recovery effort. Despite the tons of aid sent to Haiti, relatively little is known about the effectiveness of the aid or about the continuing needs ...
