Although sinkhole development in susceptible areas cannot be completely prevented, policy makers and the public can use geologic maps that delineate karst features to develop strategies that can minimize or avoid property damage and personal injuries.
Defining the Problem
Sinkholes, which abound...

Geologic mapping provides the data foundation that makes soil mapping and earthquake simulations possible. This approach also can be used to predict damage in areas where the historical record indicates a risk of potential earthquakes.
Defining the Problem
The density and value of its buildings...

Geologic maps are being used in Kentucky to identify areas that have high potential for development of karst features, such as sinkholes and caves.
Defining the Problem
A new interstate highway, I-66, is being planned to pass through the vicinity of Mammoth Cave National Park (Fig. 1). It is one...

Remote sensing imagery is used by researchers at the University of Wisconsin–Madison to support recovery efforts after a tornado.
Defining the Problem
Following a tornado, first responders need maps of the width and location (swath) of the damage area. The biggest challenge when integrating...

Surface and subsurface mapping of lahar and lahar runout deposits from Glacier Peak volcano has contributed important geologic information for land-management planning and emergency preparedness in the lower Skagit Valley.
Defining the Problem
Active volcanoes, such as Glacier Peak (Fig. 1), pose...

In Garfield County, an area of multiple land uses, geologic maps show the location and quality of the sand and gravel resources. Planners, citizens, and resource developers use this information to locate and evaluate potential deposits and make informed land-use choices.
Defining the Problem
As...
