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.
Roadside Geology Guides|
November 25, 2013 | Geology.com Store
Since 1972 the “Roadside Geology” series has provided introductory information on the geology of states and small regions of the United States.
The books provide a combination of maps, travel logs, photos and commentary for the geology that can be seen along highways or visited at parks and public viewing areas. They are popular with geologists, teachers, students and others who are interested in the Earth.

“The Bureau of Economic Geology frequently fields calls from the general public to find information about clay deposits, uranium site locations, sand and gravel deposits, or what
resources, in general, are located at or around a specific location. The interactive Map provides the public with the means to search out locations on their own, and click on the points of interest, bringing up pertinent information…”

Natural Hazard Viewer for Arizona|
September 24, 2013 | Arizona Geological Survey
The interactive Natural Hazard Viewer focuses on four hazards common to Arizona — geologic faults and earthquakes, earth fissures, floods and wildfire. Each hazard is described in detail and displayed as a layer on a map. Moreover, the natural hazard information is dynamic; site updates will occur as new or revised hazard data becomes available.
Editor’s Comment: Every state geological survey should have one of these!
