Photograph of a dirt road passing by an empty plowed field where the road turns. The photo includes an old farm plow left under a dead tree and a snow-dusted mountain in the background under a hazy winter sky.

Seismic data were collected in southwestern New Mexico to investigate the sources of the geothermal anomalies and to investigate the potential earthquake hazards of geothermal development. No major crustal structure anomalies have been located related to known geothermal resources, and no areas of continual seismicity have been identified, which is interpreted to indicate a lack of active, or recently active crustal intrusions in southwestern New Mexico. Without a magnetic heat source, the geothermal potential of the known anomalies is probably limited to intermediate and low temperature applications (<180/sup 0/C). The lack of continual seismicity indicates low seismic hazard in the area directly related to geothermal development, although the historic and geologically recent tectonic activity should be taken into consideration during any development in the area. A model of forced groundwater convection is presented to explain the geothermal anomalies in southwestern New Mexico, which is consistent with all available geological and geophysical data from the area.

From introduction: "The U.S. Geological Survey began a 5-year study of the High Plains regional aquifer during the 1978 to provide the hydrologic information needed for the development of computer models to evaluate the aquifer's response to ground-water management alternatives." It contains maps, graphs, and tables.

Photograph of a farm with a circular brick structure with a plank framed doorway. The photo includes a collapsing wood structure with shingles along with debris scattered around the land between a dead tree and the brick structure.

Photograph of mountains and a field leading into a forest in New Taos, NM. The photo shows the mountain tops dusted with snow and conifer trees of varying heights at the edge of the forest.

Photograph of the front façade of a mosque. The photo includes a wide staircase leading to a large archway framing the front double doors. The photo was taken in the parking lot with the curb visible near the bottom edge of the frame.

Photograph of a church in a small desert town in New Mexico. The photo features a large white cross at the front of a low stone wall surrounding a simple church. The church façade is symmetrical and is topped with a small white cross.

Photograph of slanted and jutting rock formations at the Garden of the Gods in New Mexico. The photo shows weathered and rocky ground leading to the formation covered in scattered desert shrubbery and trees.

Photograph of a gravestone for Harry Gable at Oakwood Cemetary in Fort Worth. The photo includes Gables stone marked with a cross and the phrase "Of Your Charity" leaned against a more weathered headstone. Harry Gable was born on May 21st, 1872.
