Precursors of a catastrophic collapse
The flanks of many island volcanoes slide very slowly towards the sea. Whether these landslides are forewarnings of a catastrophic collapse or, on the contrary, even reduce its risk, is not yet understood. Geophysicists from the GEOMAR Helmholtz Centre for Ocean Research in Kiel have now published a study in the journal Earth and Planetary Science Letters, which shows that sporadic, slow landslides on the small volcanic island of Ritter Island in New Guinea preceded a catastrophic collapse.

The moon is quaking as it shrinks
A new analysis suggests that the moon is actively shrinking and producing moonquakes along thousands of cliffs called thrust faults spread over the moon's surface. The faults are likely the result of the moon's interior cooling and shrinking, causing the surface crust to shrivel and crack like a raisin's skin. The research, published in Nature Geoscience, combines data from NASA's Apollo and Lunar Reconnaissance Orbiter missions. (2019-05-13)

When sand behaves like oil
Sand, coffee grounds and rice behave very differently than water or oil, but under certain conditions they will suddenly exhibit astonishing similarities. Scientists have found a way to better understand the behaviour of granular materials. (2019-05-08)

Rapid permafrost thaw unrecognized threat to landscape, global warming researcher warns
University of Guelph Prof. Merritt Turetsky and an international team of researchers asssessed abrupt thaw studies across the permafrost zone to estimate the overall effect. They found carbon emissions have the potential to double the climate feedback associated with permafrost thawing because abrupt thaw releases more methane. It will also have drastic effects on landscape, from altering traditional travel and hunting patterns in the North, to causing costly infrastructure damage to roads and rail lines. (2019-04-30)

Quick reconnaissance after 2018 Anchorage quake reveals signs of ground failure
A day after the Nov. 30, 2018, magnitude 7 earthquake in Anchorage, Alaska, US Geological Survey scientists Robert Witter and Adrian Bender had taken to the skies.

A slippery slope: How climate change is reshaping the Arctic landscape
Increasing ground temperatures in the Arctic are indicators of global climate change, but until recently, areas of cold permafrost were thought to be relatively immune to severe impacts. A new study by Antoni Lewkowicz, a professor in the Department of Geography, Environment and Geomatics at the University of Ottawa and published in the journal Nature Communications, however, shows that areas of cold permafrost can be vulnerable to rising summer temperatures. (2019-04-02)

More extreme coastal weather events likely to increase bluff erosion, landslide activity
Unstable slopes on Oregon's coastline could see a 30 percent jump in landslide movements if extreme storms become frequent enough to increase seacliff erosion by 10 percent, a new study by Oregon State University shows. (2019-02-26)

Landslides triggered by Hurricane Maria
Hurricane Maria hit the island of Puerto Rico on 20 September 2017 and triggered more than 40,000 landslides in at least three-fourths of Puerto Rico's 78 municipalities. In a new article from GSA Today, authors Erin Bessette-Kirton and colleagues write that 'the number of landslides that occurred during this event was two orders of magnitude greater than those reported from previous hurricanes.'

Earthquake with magnitude 7.5 in Indonesia : an unusual and steady speed
4,1 km/s along 150 km : this is the propagation speed of the 7.5 magnitude earthquake which occurred in Indonesia in September 2018. This speed has just been determined by an international team of researchers from the French National Research Institute for Sustainable Development (IRD-France), Université Côte d'Azur, University of California Los Angeles and California Institute of Technology. The results, which also shed light on the earthquake rupture path, are published on February 4th in Nature Geoscience. (2019-02-04)

One million years of precipitation history of the monsoon reconstructed
With its wind and precipitation patterns, the South Asian Monsoon influences the lives of several billion people. Recent studies indicate that its drivers are more complex than previously assumed. Scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel have now published a reconstruction of precipitation over the eastern Indian Ocean over the past one million years in the international journal Nature Communications. It points to connections with controlling processes in the southern hemisphere that have received little attention so far. (2018-11-08)

Can 'microswimmers' swim through jelly?
Researchers from Tokyo Metropolitan University have studied how microswimmers, like bacteria or sperm, swim through fluids with both solid and liquid-like properties e.g. gels. They found that subtle changes in swimmer features, its structure and how it moves, invoke a dramatically different response from the fluid. They also discovered that the similarity in size between the structure of the fluid and the swimmer led to a wide range of interesting behavior. (2018-08-27)

Landslides triggered by human activity on the rise
More than 50,000 people were killed by landslides around the world between 2004 and 2016, according to a new study by researchers at UK's Sheffield University. The team, who compiled data on over 4,800 fatal landslides during the 13-year period, also revealed for the first time that landslides resulting from human activity have increased over time. The research is published today in the European Geosciences Union journal Natural Hazards and Earth System Sciences. (2018-08-23)

Stable gas hydrates can trigger landslides
Like avalanches onshore, there are different processes that cause submarine landslides. One very widespread assumption is that they are associated with dissociating gas hydrates in the seafloor. However, scientists at GEOMAR Helmholtz Centre for Ocean Research Kiel have now found evidence that the context could be quite different. Their study has been published in the international journal Nature Communications. (2018-02-20)

Why the seafloor starts moving
When the seabed loses its stability and starts to move, it often happens in much larger dimensions than landslides ashore -- and at slopes with very low gradients. At the same time, discplacement of large amounts of sediment under water scan cause devastating tsunamis. However, why and when submarine landslides develop is hardly understood. Marine scientists from GEOMAR Helmholtz Centre for Ocean Research Kiel have now published possible causes based on observations on submarine landslides off the coast of northwest Africa in the international journal Geology. (2018-02-13)

Changing climate to bring more landslides on logged land, say WSU researchers
Washington State University researchers say landslides on logged forests will be more widespread as the Northwest climate changes. In a study modelled on clear-cut lands on the Olympic Peninsula, they anticipate the climate of 2045 and conclude that there will be a 7 -11 percent increase in the land that is highly vulnerable to landslides. The researchers say their findings are applicable to the Cascade Mountain Range area as well. (2017-11-09)
