The timing of the landslide season in Nepal

Using my fatal landslide database for Nepal, I’ve looked at the timing of the landslide season in recent years. The main landslide season starts in late June and runs to early October.

Landslides in Nepal and the impact of the SW Monsoon

In a paper (Petley et al. 2007), we looked at spatial and temporal patterns of landslides in Nepal. The results highlight the threat posed by the SW monsoon in the earthquake affected areas

It’s 2015. We respond to earthquakes from space.

The seismic waves ringing out from Nepal on April 25 reached sensors around the planet, mobilizing a vast, remote response that’s truly a sign of the times in modern seismic disaster recovery. While Kathmandu and the surrounding towns and villages stood shocked and crippled by the now-named Gorkha earthquake, satellites sweeping by overhead quickly gathered a picture of the scene, transmitting intricate detail of the disaster to the world with …

Where To Get Some Good Science on The Nepal Quake

I thought I would put together a few links to some good early science reporting on the Nepal Quake. First up is Dave Petley’s Landslide Blog here on the AGU Blogosphere. Dave has some good basic facts on the quake. The Washington Post has a good piece that quotes Geologist Roger Bilham who is an expert on quakes in this region, and he says that this was a severe quake …

Tearing through California Part 1: the Central San Andreas

On display in central and northern California is the rare and troublesome phenomenon that’s the mischievous cousin to sudden, wrenching earthquakes: slow, steady fault creep. Rather than remaining pressed firmly together until they lurch past each other in violent earthquakes, the two sides of a creeping fault glide gradually along, generally silently carrying along everything above them. The good news is that this process takes up strain that would otherwise be …

Hollywood and the USGS both have announcements about California quakes

The last day has been chock full of big public-facing announcements regarding earthquakes, so it’s a good time to step in and sort them out, as well as a good time for (real life) earthquake scientists to capitalize on the surge of awareness. The big real news comes from the USGS, which has finalized and released the most advanced seismic hazard model of California to date, the Uniform California Earthquake Rupture …

Earthquake faults identified in surge of Oklahoma quakes

New research has revealed the faults associated with more than 3,600 earthquakes that have been recorded in Oklahoma since 2009. The study also finds that recently reactivated ancient faults in the center of the state could generate higher-magnitude and more destructive earthquakes than the region has experienced since earthquake activity picked up there five years ago.

A haunting 8-day-long orchestration of modern seismicity

We’re getting ever-richer ways to “view” the seismic restlessness of our planet, from this beautiful map of all the tremors we’ve recorded, and this sparkling NOAA animation of quakes in the past decade (or the last year), to the of tympanic drama of individual earthquake sequences. At the same time, artists find inspiration for performance in the fundamental natural rhythms of the planet, staging ballets and concerts backed with live seismic recordings, and composing music derived from seismograms …

Heaven Above and Earth Below: Scientists Track Atmospheric Disturbances to Gather Earthquake Data

Earthquakes generate seismic waves that propagate through earth, water, and air. Generations of geologists have used ground-based seismometers to decipher information about earthquakes, including magnitude, epicenter, depth and tsunami danger. But more recently some researchers have wondered if seismic waves traveling through the air also carry traceable information about the earthquake that generated them. If so, measuring seismic waves in the atmosphere could potentially speed up earthquake reporting systems and improve the accuracy of tsunami alerts.
