The software package, Grfin Tools, can estimate potential runout from landslides or inundation from geophysical mass flows such as debris flows, lahars from volcanoes, and rock avalanches within a digital elevation model (DEM). Grfin is an acronym of growth + flow + inundation. The tools within this package apply simple, well-tested, empirical models of runout that are computationally efficient and require minimal parameters. These tools can be used individually (for example, to estimate debris-flow inundation) or in combination to represent a more complete series of linked processes, from landslide source areas, to unchannelized transport, to channelized flows. Grfin Tools can rapidly assess potential runout and inundation over large areas and the results are readily visualized in a geographic information system.Tools for assessing areas affected by runout and flow inundation include a height-to-length (H/L) ratio, angle-of-reach approach for estimating open-slope, unchannelized landslide runout, and volume-area scaling relations for assessing flow inundation...
#Kanlaon has been under Alert Level 2 since June 3, following a “moderately explosive eruption” that forced residents living near the #volcano to evacuate, caused #ashfall, triggered #lahar and even killed thousands of farm animals.
An average of 10 volcanic #earthquakes per day has been recorded since the eruption, while Kanlaon’s edifice has been inflated or swollen since March 2022.
#KanlaonVolcano #SulfurDioxide reaches record high on June 28

Dozens killed in cold lava mudslides on Indonesian island of Sumatra
Heavy rains triggered flash floods and caused torrents of cold lava and mud to flow down a volcano’s slopes on Indonesia’s Sumatra island, killing at least 41 people and leaving more than a dozen others missing, officials have said. Monsoon rains and a major mudslide from a cold lava flow on Mount Marapi caused a river to... #sumatra #indonesia #asiapacific #southeastasia #asia #lahar #lava #volcano #civilemergency #worldnews #worldwithoutus
A 22-million-year-old petrified #mangrove forest found in the Panama Canal https://phys.org/news/2024-01-million-year-petrified-mangrove-forest.html
An early #Miocene (#Aquitanian) mangrove #fossil forest buried by a #volcanic lahar at #BarroColoradoIsland, #Panama https://www.sciencedirect.com/science/article/abs/pii/S0031018223006247
"approximately 1 million years after the formation of #BarroColorado Island, a #volcano erupted, followed by a #lahar, which covered the island with mud and rocks. It also covered the #MangroveForest that had grown around the edges of the island."
A team of environmental and natural scientists from Universidad EAFIT in Colombia, the Smithsonian Tropical Research Institute in Panama, and Boise State University in the U.S. has found evidence of an ancient petrified mangrove forest on an island in the Panama Canal. For their study, reported in the journal Palaeogeography, Palaeoclimatology, Palaeoecology, the group collected fossils and sediment samples from the island.
When they said, “#PugetSound is built on #Rainier’s mudflows,” I didn’t realize they meant that there was no land where Tacoma, Kent, Auburn, and Renton currently are before the colossal #OsceolaMudflow filled in those parts of Puget Sound 5600 years ago.
Via the U.S. Geological Survey, on Tuesday, a small debris flow was detected by several of Mount Rainier's lahar monitoring stations, likely the result of an outburst of water from the South Tahoma Glacier that grew into a debris flow, which isn't surprising given the current heat wave in WA.
