What Your Homeowner’s Insurance Does Not Cover|
March 4, 2014 | Geology.com
Most homeowners insurance policies have exclusions that make them worthless when the home is damaged by common geologic problems such as floods, earthquakes, landslides, mine subsidence, cavern collapse and expansive soils. When a home is damaged the homeowner often is surprised that his “all perils” policy has these exclusions.
Hunting Landslides in Alaska|
March 2, 2014 | Wired Science
“You might think it’d be hard not to notice 68 million tons of rock and debris suddenly crashing down a mountainside. But when one of the biggest landslides of the past four years occurred in a remote region of Alaska, researchers knew almost everything about it except its exact location.” Quoted from Adam Mann’s blog post on Wired Science.

The Seti River Disaster|
January 28, 2014 | NASA Earth Observatory
The first sign of trouble for residents along the upper Seti River in Nepal was the water. In late April and early May 2012, what was usually a roaring river had slowed to a trickle. And the milky-white water—colored by rock flour from glaciers upstream in the Sabche Cirque—had turned blue and clear. Residents regarded the river changes as bizarre, but nobody connected the slowdown to anything dangerous upstream. So it came as a surprise when a slurry of sediment, rock, and water suddenly surged through the valley on May 5, 2012, obliterating dozens of homes and sweeping 72 people to their deaths.
Hear Earthquakes Triggered by the Bingham Canyon Mine Landslide|
January 7, 2014 | The University of Utah
“Last year’s gigantic landslide at a Utah copper mine probably was the biggest nonvolcanic slide in North America’s modern history, and included two rock avalanches that happened 90 minutes apart and surprisingly triggered 16 small earthquakes.” Quoted from The University of Utah press release.
The story is accompanied by a sound file that allows you to hear the second rock avalanche followed by three earthquakes.

Floods and Landslides in Brazil|
January 2, 2014 | NASA Earth Observatory
“Widespread floods are plaguing at least three states in southeast Brazil. Heavy rains lasted throughout December in Minas Gerais, Bahia, and Espirito Santo States, causing floods and mudslides. December rainfall in Espirito Santo has already reached 714 millimeters (28.11 inches), an all-time record monthly rainfall.”

“The risk posed by tsunami waves generated by Canary Island landslides may need to be re-evaluated, according to researchers at the National Oceanography Centre. Their findings suggest that these landslides result in smaller tsunami waves than previously thought by some authors, because of the processes involved.” Quoted from a National Oceanography Centre press release.

Landslide Mapping Needed in North Carolina|
November 26, 2013 | WSPA.com
Hundreds of landslides occur every year in North Carolina but lawmakers have almost eliminated a program that can help developers avoid building homes, commercial and public buildings on ancient landslides and slide-prone areas. It can also help the state highway department and utility companies avoid building roads and pipelines across ancient landslides and slide-prone areas. This one-time job was costing about $350,000 per year and would only require mapping the western part of the state where most landslides occur.
In a 24-year period landslides in the state killed 7 people and destroyed 85 homes. Not available is how much is spent on repairs to roads and utilities. The annual cost of these is undoubtedly many times the cost of the landslide mapping program – which is temporary.
The economics of this project suggests that millions per year should be spent to get it done as quickly as possible – but lawmakers decided to cut it.
