California is a state that becomes prone to earthquake. This state is located on the plate boundary of Pacific and North American plate, grinding each other. A clear evident of this place is at the plate boundary is the existence of San Andreas Fault zone. It is extended across west of San Francisco Bay, Hayward fault and Rodgers Creek fault.
A year after earthquake in Napa, another 4.0 magnitude earthquake struck north of Hayward fault. This tremble was identified as quick brief quake. This tremble happened after 4 weeks commemoration that there would be big quake in Hayward fault. A lot of constructions have been damaged. A worth of three hundred thousand million US dollars destruction was incurred in Napa Valley earthquake. There was also a year of commemoration of Napa Valley earthquake.

The Nazca tectonic plates is actually subducting under the South American tectonic plates. They converge as much as some centimeters a year. The convergence of Nazca and South American tectonic plates actually had raised the highs of magnificent Andes Mountain.
