Landslides from the Mw=7.3 17 December 2024 Port Vila Earthquake in Vanuatu
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. It has been widely reported that an M=7.3 earthquake struck Vanuatu on 17 December 2024 at 12:47 local time. Wikipedia is referring to this as the Port Vila Earthquake as the epicentre […]
120 Years of Geodetic Data on Kīlauea’s Décollement
A new study explores the deformation and stress changes of Kīlauea’s décollement from 1898 to 2018 by collating an unprecedented 120 years of geodetic data.
The mobility of landslides triggered by earthquakes
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. A key determinant of the ability of a landslide to cause loss is its mobility. A more mobile landslide has greater potential capacity to impact humans and their assets, and faster movement […]
Creeping Faults May Have Simpler Geometries
A recent study offers an alternative perspective on why some fault segments slide smoothly, whereas others get stuck and produce earthquakes.
The 8 October 2005 Hattian Bala landslide in Pakistan
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. I was recently pondering some of the most interesting landslides on which I have worked during my career, and was reminded of the 8 October 2005 Hattian Bala landslide in Kashmir, Pakistan. […]
Sedimentos Caribenhos Rastreados até o Terremoto e Tsunami Português de 1755
Arqueólogos escavando na Martinica encontraram por acaso o primeiro depósito de tsunami do terremoto encontrado no Novo Mundo. Ao que parece, o tsunami deixou um forte rastro, pois a onda passou por cima de um rio.
Earthquakes May Lace Quartz Veins with Gold
Seismic activity may kick off chemical reactions that seed nuggets of gold.
Seismotectonic Update of the Philippines-Taiwan Region
Using more than two decades of data, scientists find that the Philippine and Taiwan subduction region is controlled mainly by shallow seismicity and low magnitude earthquakes.
Volcanic Anatomy, Mapped as It Erupts
Testing during the 2021 Tajogaite eruption on La Palma demonstrated the value of near-real-time petrological analyses as a supplement to seismic and geochemical data for eruption monitoring.
