Our military is drilling hydrothermal plants up and down the northern reaches an area of spreading tectonic plates, in other words, a rifting zone. The area from Crater Lake to the north all the way down to the Sea of Cortez, between mainland Mexico and Baja, and 7000 miles beyond - is an active rifting zone. This is an area where the crust is thin, and where new land is being built via volcanism. The military is drilling near the Coso volcano system and at Hawthorne, Nevada, where harmonic tremors are believed to be going on for weeks, and still going on as of this writing. Often, a hot magma chamber is the thing that heats of water and steam for these plants to tap into. Just south of Mexicali, Mexico, at the Cerro Prieta volcano, there is the world's second largest geo-thermal powerplant!
We need magma awareness before drilling for hydrothermal energy.
