The largest landslide in modern U.S. history
(in terms of volume) was most likely one that occurred in 2013 Bingham
Canyon outside of Salt Lake City, Utah. It had a slide mass of 55 million cubic meters (compared to an
estimated 10 million cubic meters during the Oso, Washington event).
Fortunately, no one was injured or killed during the Utah slide.
Landslides impact
California’s terrain often. These are generally related to precipitation
patterns, in particular if there has been previous months of drought
conditions. Early this year, across Southern California, heavy rain was
causing numerous mudslides
and road closures in burn scar areas from recent wildfires. The image
on the right clearly shows what type of enormous devastation we are talking about [the
total death toll was 20]. That area was previously burned by the Thomas fire, the biggest wildfire
in CA’s recorded history, so it is not surprise that heavy rain provoked this
mudslides, as the soil had no holding vegetation left.
This is the USGS page with information on how to identify any types of mass wasting events [landslides, mudslides] and what to do if one happens. If you want to know if you are living in a risk area, you can access maps like the USGS below, that shows the Emergency Assessment of Post-Fire Debris-Flow Hazards.
