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.
Zoom in on the San Andreas Fault|
December 5, 2013 | Geology.com
After being down for a couple of days for a software update, our interactive San Andreas Fault map is back in action. You can use it to follow the approximate trace of the fault from the Salton Sea in Southern California to near Shelter Cove, north of San Francisco. For more information about the San Andreas Fault visit SanAndreasFault.org, a website by Dr. David Lynch, who provided data used to make the interactive map.

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.
