Earthquakes are natural phenomena that occur when there is a sudden release of energy in the Earth’s crust, resulting in seismic waves. This release can be triggered by various factors, including tectonic plate movements, volcanic activity, or human-induced activities such as mining or reservoir-induced seismicity. The intensity and duration of an earthquake are measured using the Richter scale or the moment magnitude scale (Mw), which provide a quantifiable measure of the earthquake’s energy release.
The geological makeup of an area significantly influences how seismic waves propagate, which can lead to varying levels of impact even within relatively close proximity to the epicenter. In regions like California, where tectonic activity is prevalent due to the San Andreas Fault and other fault lines, understanding the mechanics of earthquakes is crucial for preparedness and response. The state has experienced numerous significant earthquakes throughout its history, with some of the most notable being the 1906 San Francisco earthquake and the 1994 Northridge earthquake.
These events have shaped not only the physical landscape but also the policies and practices surrounding earthquake preparedness and response.
