Large earthquakes initiate chains of surface processes that last much longer than the brief
moments of strong shaking. Most moderate‐and large‐magnitude earthquakes trigger …

Distributed acoustic sensing (DAS) is a new, relatively inexpensive technology that is rapidly
demonstrating its promise for recording earthquake waves and other seismic signals in a …

The ability to rapidly assess the spatial distribution and severity of building damage is
essential to post-event emergency response and recovery. Visually identifying and …

Geodesy, the oldest science, has become an important discipline in the geosciences, in
large part by enhancing Global Positioning System (GPS) capabilities over the last 35 years …

This paper presents a statistical analysis of structural fragility curves. Both empirical and
analytical fragility curves are considered. The empirical fragility curves are developed …

Abstract<? A3B2 twb=. 3w?> This paper describes refinements to the hybrid broadband
ground-motion simulation methodology of, which combines a deterministic approach at low …

We describe a technique to derive first-order site-condition maps directly from topographic
data. For calibration, we use global 30 arc sec topographic data and VS 30 measurements …

We have developed regression relationships between Modified Mercalli Intensity (Imm) and
peak ground acceleration (PGA) and velocity (PGV) by comparing horizontal peak ground …

The US Geological Survey (USGS) is investigating how the social networking site Twitter, a
popular service for sending and receiving short, public text messages, can augment USGS …

On the night of February 6, 2023, a major earthquake struck Turkey and nearby Syria, whose
moment magnitude (M) was estimated at 7.8 (or 7.7, depending on the data source). It …
