The Icy Bay landslide in Alaska: a nice video describing the link with glacial melting

. The Icy Bay landslide in Alaska A very nice video has been posted on Youtube describing the link between the giant Icy Bay landslide in Alaska in 2015 (this landslide is also variously known as the Taan Fjord landslide and the Tyndall Glacier landslide), which is the largest known recent landslide in North America, and the melting of the adjacent glacier.  The video features Dr Michael Loso, physical scientist …

Complex, compound New Zealand earthquake – Part 2: Faulting by Day

Reeling from the massive M7.8 earthquake at midnight, its relentless aftershocks, and the continuing coastal threat of tsunami, New Zealanders awaited daylight on Monday to see the full extent of the destruction. The bizarre seismic records observed overnight had raised confusion and speculation about what faults were to blame for this earthquake. With an epicenter on land but also a several meter tsunami, it was clear that some complicated combination of on- …

My latest paper: hillslope preconditioning

In a new paper, we examine the distribution of landslides from two earthquakes in New Zealand to see if hillslope preconditioning – the idea that the legacy of one trigger event can influence slope behaviour ins subsequent event – occurred. The results suggest that this might have been a factor in the area affected by both earthquakes,

Earthquakes shake NZ capital

New Zealand is at it again–or as usual–seismically. This time a series of strong earthquakes in the Cook Strait culminated Sunday morning with a M6.5 between the South and North Islands, shaking the national capital of Wellington and exacting a fair bit of damage around the region. The shocks started with two oddly steep convergent events, a 5.3 Friday morning and a 5.8 in the wee hours Sunday morning. Each …
