Bedrock Geology of the Ranges Bounding the Wells Earthquake of February 21 , 2008

The Wells 6.0 magnitude earthquake of February 21, 2008, occurred on a previously unrecognized northeast-striking southeast-dipping fault situated beneath Town Creek Flat, a few miles north of Wells, Nevada. Focal depth of the earthquake was 5 miles (8 km). Bedrock geology in the surrounding ranges did not indicate the existence of the fault prior to the earthquake, and no surface rupture has b...

Hazard Ranking Method for Populations Exposed to Arsenic in Private Water Supplies: Relation to Bedrock Geology

Approximately one million people in the UK are served by private water supplies (PWS) where main municipal water supply system connection is not practical or where PWS is the preferred option. Chronic exposure to contaminants in PWS may have adverse effects on health. South West England is an area with elevated arsenic concentrations in groundwater and over 9000 domestic dwellings here are supp...
