What Your Homeowner’s Insurance Does Not Cover|
April 22, 2013 | 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.

Ecological Modeling and the Fossil Record|
January 10, 2013 | Southern Methodist University
“Carbon dioxide levels in fossil soils from the Late Jurassic confirm that climate, vegetation and animal richness varied across the planet 150 million years ago, suggesting future human changes to global climate will heavily impact plant and animal life.”
Interactive Hazards Map of Oregon|
November 12, 2012 | Oregon Department of Geology and Mineral Industries
“The HazVu map provides a way to view many different geohazards in the state of Oregon. You can enter the address for your home, school, business, or public buildings in your area to see what hazards might affect you. You can print the map you create.
Geohazards include 100-year flooding; Cascadia Subduction Zone earthquake shaking and tsunami; coastal erosion; volcano; landslide; active faults; earthquake soft soil; and more. Assets include state-owned/leased facilities and public buildings such as schools, police and fire stations, and hospitals, as well as links to seismic assessment reports for these public buildings.” Quoted from the HazVu website.

Drought-Induced Crop Lines|
October 8, 2012 | Illinois Geological Survey
“Extreme drought conditions during the summer of 2012 resulted in the formation of crop lines, a rare feature that mimics underlying crevices that make up the karst bedrock aquifer in the Driftless Area, northwestern Illinois. Georeferenced aerial photographs of the lines are being used to map the crevice geometry of the aquifer, reveal the nature of lineaments only seen in LiDAR imagery, and are being used in conjunction with road cut and quarry mapping, to characterize the aquifer in three dimensions.” Description and photo courtesy of Samuel V. Panno.

Phosphorus and Groundwater|
June 26, 2012 | USGS
“The study design included assessment of a variety of agricultural practices, especially cropping patterns and irrigation, so that the factors that contribute to phosphorus movement to groundwater, or sequestration of the phosphorus to soil could be compared and examined. This type of information could potentially be used to formulate best management practices to limit the transport of phosphorus from the agricultural fields.” Quoted from the USGS press release.
