A new interactive tool is helping residents understand how their lands and homes are at risk.
The Baildon landslide in West Yorkshire
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. On 5 February 2024, a railway cutting failed on the edge of Baildon in West Yorkshire, England. As a consequence, the railway line, an important route linking towns across the region, was […]
How Earthquakes Grow from a Tiny Fracture to a Catastrophic Event
State-of-art numerical simulations illustrate how a small-scale shear instability can become a giant earthquake in a manner that is consistent with seismological observation.
Another significant landslide in the Hollywood Hills
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. California continues to suffer repeated bouts of heavy rainfall, probably associated with the El Nino conditions that have been in place through the winter. On 24 March 2024, the rainfall triggered another […]
GNS Science Landslide Planning Guidance
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. New Zealand is a country with a severe level of landslide hazard, resulting from a combination of the tectonic setting, the geology, the climate and the impact of human activities. It is […]
Where and How Sea-Level Rise Threatens Coastal Areas and Communities
To better understand how sea-level rise threatens coastal areas, scientists propose a new indicator to estimate the risk of coastal flooding under climate change.
A transnational, valley-blocking landslide in Africa
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. On 23 February 2024, a large valley-blocking landslide was triggered by heavy rainfall in the Ruzizi Valley, to the south of the city of Bukavu, which is in the Democratic Republic of […]
Submarine Avalanche Deposits Hold Clues to Past Earthquakes
Scientists are making progress on illuminating how undersea sedimentary deposits called turbidites form and on reconstructing the complex histories they record. But it’s not an easy task.
