New research could prompt a shift in thinking about New Zealand’s Alpine Fault.

Researchers at Rice University, the University of Toronto, and Princeton University generated 3-D maps of the Earth under the Hangai Dome in central Mongolia from seismic data. The 3-D image below shows the earth under the dome. Colored yellow, warm rock rises up from the deep mantle toward the Earth’s surface. The pressure on the rock drops as it rises. When the rock reaches 150 kilometers (93 miles) below the surface, it starts to melt and form magma, illustrated in red. Heat released by the magma modifies the rigid outer layer of the Earth that becomes lighter and rises up, creating the Hangai Dome.

Tsunamis generated by earthquake faults off the Santa Barbara coast could pose a greater danger to the cites of Ventura and Oxnard than previously thought.

During a brief visit to California this week, I, along with a metroregionfull of people, was treated to a rattling little temblor from the Hayward Fault. The quick jolt struck conveniently just before everyone’s morning alarms went off, serving as a wakeup call for the day, and as this season’s broader “wakeup call” reminder that there are big active seams in the crust inching along around and below our cities. …

In 1570, a 5.8-magnitude earthquake struck the northern Italian city of Ferrara, causing dozens of deaths, major damage to the city and thousands to flee. At the time, Pope Pius V said God sent the earthquake to punish the city’s duke who had given hospitality to Jews and Marranos who had escaped Spain.
Now, a new study finds that the 16th century earthquake and subsequent aftershocks were the last step in a tectonic process that occurred over thousands of years and changed the course of the Po River. The final rerouting of the river left Ferrara dry by the end of the 16th century, an event depicted in a painting that now hangs in the Vatican Museum.

Heavy rainfall triggered landslides on Wednesday night in Central Nepal, killing at least 35 people. Worst affected were Kaski and Myagdi districts

In June 1692 the Port Royal earthquake triggered the Judgement Cliff Rock Avalanche in Jamaica, killing at least 19 people

The Straits Times in Singapore has published a detailed account of the Mount Kinabalu earthquake and rockfalls from the perspective of the school party that was struck by the debris on the mountain slopes.

The EWF project has published a revised map showing landslide density for the Nepal earthquakes in April and May.

The Araniko Highway is the main route that links Nepal with Tibet. In the wake of the recent earthquake it is facing major landslide problems in the monsoon

Landslides caused by the 5th June 2015 Sabah earthquake in Malaysia have released large amounts of sediment that is now causing extensive damage downstream

The Mount Kinabalu rockfall on Friday, induced by a M=6.0 earthquake, is now known to have killed 19 people, including school children from Singapore

Early reports suggest that the M=6.0 Malaysia earthquake this morning may have triggered landslides and rockfalls, especially on Mount Kinabalu, where five climbers are thought to have been killed.

When the ground shook throughout Nepal in April, it was neither predicted nor surprising–the paradox of inevitable but chaotic large earthquakes within well known seismic zones. Though warnings of Nepal’s catasrophic earthquake risk have been sounded for years, and though this magnitude 7.8 and its energetic 7.3 aftershock wrought plenty of death, destruction, and tragedy, scientists are finding themselves somewhat surprised at the apparently rather limited degree of overall damage …

On Sunday a landslide blocked the Kali Gandaki river in Nepal for about 15 hours before breaching to release a significant flood.

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.

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

A new, very good video has been posted on Youtube showing landslides at Jalbire triggered by the Gorkha earthquake in Nepal
6 May 2015
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 …
The EWF team, working with the British Geological Survey, have provided an update on landslide hazard after the Gorkha earthquake, including a landslide map
