Seismometer readings could offer debris flow early warning
Instruments designed to record earthquakes revealed information about debris-ﬂow speed, the width of the ﬂow and the size of boulders carried by the January 2017 mudslide in Montecito, California, and the location of the event, suggesting that the current generation of seismometers in the ﬁeld could be used to provide an early warning of an incoming debris ﬂow to residents in mudslide-prone areas.

Fungi make steep slopes more stable
Fungi are fantastic. They give us beer, bread and cheese. And if those delicious reasons aren’t sufficient, then here’s another: a new study suggests some fungi can help prevent shallow landslides and surface erosion.

Oso disaster had its roots in earlier landslides
The disastrous March 22 landslide that killed 43 people in the rural Washington state community of Oso involved the “remobilization” of a 2006 landslide on the same hillside, a new federally sponsored geological study concludes.

Where it burns, it floods: predicting post-fire mudslides in the West
By Alexandra Branscombe WASHINGTON, DC – Just a week after a 21,000-acre wildfire between Sedona and Flagstaff, Arizona, residents there are already bracing for mudslides that could surge down the burned slopes. These water-fueled flows of burned-out trees, loose rocks and mud can pack enough power to wipe out homes and roads. A new online hazard assessment system could help threatened communities in central Arizona and elsewhere in the western …

Stealthy but slipping: Researchers reveal slow-moving landslides in southern Italy
Disaster didn’t strike overnight in the town Motta Montecorvino, Italy. Rather, a slow-moving landslide is tearing the hilltop community apart a few painful centimeters a year. Leaning telephone poles and ominous cracks in walls tell the tale of a town sliding away.

Extreme natural hazards span the globe
I lived in Houston, but our town was dusted by a fine layer of Washington state, 3000 kilometers away after Mount St. Helens blew its top in 1980. But that was really not that remarkable, according to a global database of explosive eruptions presented in FM10’s session on U13B. Similar studies reported throughout the conference–on volcanoes, landslides and tsunami–also assembled global databases of extreme geological hazards to better know when and where such threats might loom.
