Fault lines in northern california
The San Andreas fault is capable of magnitude 7.8 earthquakes. Two have occurred twice in recent times: the 1906 San Francisco earthquake and one in 1857 in Southern California.Eclogite consists of green omphacite (a variety of pyroxene) and prominent red pyrope (a variety of garnet). This outcrop appears on Ring Mountain, near Tiburon, California. Eclogite is very dense. Depending on the location sampled, the density of eclogite ranges from 3.45 to 3.75 g/cm 3.In the past 150 years, nearly 40 earthquakes of magnitude 6 or larger have affected Northern California. Most of these earthquakes were centered on faults nearby. But very large earthquakes located elsewhere in the Pacific basin, like the 1964 magnitude 9.2 Alaska earthquake can generate tsunamis that threaten our coast.
