Geothermal energy in the United States; Part II, Assessment of resources

Geothermal energy-from heat deep inside the Earth- is a vast potential source of power. This article is the second part of a series on geothermal energy, the first part of which was in volume 8, number 1, of the Earthquake Information Bulletin (January-February 1976). Part 1 of this series described the categories of the geothermal resource base.

A major geothermal anomaly in the Gulf of California

We have mapped a 3-km wide, high heat flow anomaly with a maximum value of 30 μ calorie cm −2 s −1 within a zone of seafloor extension in the central Gulf of California. From seismic reflection data and thermal modelling we suggest that the anomaly is caused by a 1-km wide basaltic intrusion which is roughly 100 m deep and less than 18,000 yr old.
