Hi Pavel,

We do have many mines here in my locale. I do know the owners of these claims. The link shows The Eagle/High Peak mines, which are several hundred feet deep. The mines are now a tourist attraction, but there are many meters of hard rock tunnel that people are not allowed into. The mines followed ore viens which are pitched 70 degrees, uplifted Julian schist formed by the early subduction process that formed the Penninsular Range from Baja Califonia and terminates south of Los Angeles.

I might also mention that these mines are remote from artificial noise, such as railroads or road traffic. One branch of the Elsinore Fault crosses through the Eagle mine, and created shoring problems due to fault creep. My guess is that sufficient equipment would sense the aseismic creep of the Elsinore fault, and may sense the small quakes in the Anza Seismic Gap, which is about 50 Km north of these mines. Also the mine is about 40 Km from the Coyote Creek segment of the San Jacinto Fault, and about 80 Km from the Coachella segment of the SAF, a ticking time bomb.

I'll get back with more if you are interested. The owners of these mines are heavy into geology. They have to be. I think they would be very interested in a scientific project like you have proposed.

Let me know.
Glen
