SCEC2020 Poster Archive Now Available

The SCEC2020 Archive of our poster is now available. The poster includes our study of the correlation of the observations with basement depth and Vs30, as well as a comparison of the data with 3D finite difference simulations predictions.

Wired Article

Our Ridgecrest earthquake sequence Seismological Research Letters paper was featured on Wired.

Animations from the 2019 M7.1 Ridgecrest Earthquake

Movies of the ground velocities and ground displacements in urban Los Angeles during the strong motion part of the Mw7.1 2019 Ridgecrest earthquake.

Los Angeles Downtown Highrises Ridgecrest Amplification

We calculate the ground-motion amplification factors in urban Los-Angeles. Acceleration measurements from the main M7.1 2019 Ridgecrest earthquake are used. The Los Angeles downtown hig-rise building could had experienced a much higher amplification if located just a few blocks to the south.

IWSHM2019 Proceedings: Identification of Sparse Damage in Steel-Frame Buildings Using Dense Seismic Array Measurements

L1 regularization and sparse Bayesian learning techniques are developed and tested for their effectiveness for identifying the location and size of damage in buildings. Encouraging results are obtained by applying the methods to selected types of linear and nonlinear building models and damage scenarios using simulated acceleration response time histories. Part of my presentation in the 12th International Workshop on Structural Health Monitoring (IWSHM2019).
