Tiny microbes make a surprisingly big contribution to carbon release
As erosion eats away at Earth's surface, some types of rocks release carbon they contain back into the atmosphere -- and now a new study suggests that microbes play a substantial role in this release. (2018-04-12)

NASA calculated heavy rainfall leading to California mudslides
Winter rains falling on recently burned ground triggered deadly mudslides in Santa Barbara County, California on Jan. 9. NASA calculated the amount of rain fall between Jan. 8 and 10, 2018 and calculated the potential for landslides. (2018-01-11)

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.' (2019-02-07)

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.

Ground failure study shows deep landslides not reactivated by 2018 Anchorage Quake
Major landslides triggered by the 1964 magnitude 9.2 Great Alaska earthquake responded to, but were not reactivated by, the magnitude 7.1 Anchorage earthquake that took place 30 November 2018, researchers concluded in a new study published in Seismological Research Letters. (2019-10-23)

NASA's GPM Satellite observes Tropical Cyclone Dahlia and landslide potential
On Nov. 29 Tropical Cyclone Dahlia became the first tropical cyclone of the 2017-2018 Southwest Indian Ocean season.

Heavy rainfall has created the potential for landslides and NASA analyzed areas that may be subject. (2017-12-01)

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)

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)

Genetic profile reveals susceptibility to cleft palate
For the first time, researchers from the University of Pittsburgh School of Dental Medicine have identified a series of genetic mutations that appear to be linked to significant risk for cleft palate and other dental abnormalities. These are devastating conditions that cause tremendous social isolation, and also are associated with decreased lifespan, a higher risk of cancer and increased susceptibility to psychiatric disorders, even after surgical repair. (2008-09-15)

Study models Tsunami Risk for Florida and Cuba
While the Caribbean is not thought to be at risk for tsunamis, a new study by researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science indicates that large submarine landslides on the slopes of the Great Bahama Bank have generated tsunamis in the past and could potentially again in the future. (2016-12-14)

Behind The Scenes In The Pacific Northwest Flooding
The floods have crested and are beginning to recede in most places in the Pacific Northwest. Nevertheless dozens of U.S. Geological Survey personnel, who were busy over the holidays measuring the high streamflows and keeping river stage monitors operating, are still busy in the field and in their offices. Field crews have been hampered by mudslides, road closures, and extremely dangerous conditions. Many sites cannot be reached. (1997-01-03)

Mega-landslide in giant Utah copper mine may have triggered earthquakes
Landslides are one of the most hazardous aspects of our planet, causing billions of dollars in damage and thousands of deaths each year. Most large landslides strike with little warning -- and thus geologists do not often have the ability to collect important data that can be used to better understand the behavior of these dangerous events. The April 10, 2013, collapse at Kennecott's Bingham Canyon open-pit copper mine in Utah is an important exception. (2014-01-07)
