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.

No Earthquake Deaths in Alaska Since 1964|
February 23, 2014 | Anchorage Daily News
The last deadly earthquake in Alaska occurred in 1964. It killed 131 people in Alaska and 16 more by tsunamis in Oregon and California. In the last 50 years there have been no earthquake deaths in Alaska even though several large earthquakes have occurred. Has that been luck?
Surprise Eruptions from Dormant Volcanoes??|
February 18, 2014 | Oregon State University
“A new study suggests that the magma sitting 4-5 kilometers beneath the surface of Oregon’s Mount Hood has been stored in near-solid conditions for thousands of years, but that the time it takes to liquefy and potentially erupt is surprisingly short – perhaps as little as a couple of months.” Quoted from the Oregon State University press release.

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.
The Largest US Earthquake|

Can CO2 Injection Trigger Earthquakes?|
December 8, 2013 | The University of Texas at Austin
“A new study correlates a series of small earthquakes near Snyder, Texas between 2006 and 2011 with the underground injection of large volumes of gas, primarily carbon dioxide (CO2) — a finding that is relevant to the process of capturing and storing CO2 underground.” Quoted from the Jackson School of Geosciences 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.
