(TNS) - This week marks 30 years since the massive 6.9 magnitude Loma Prieta earthquake hit the Bay Area, killing 63 people, injuring nearly 4,000 and causing extensive damage that left thousands homeless.

Generally, people in this part of the state are not too concerned about quakes. Should they be?

The reports are usually just far enough away from the Yuba-Sutter area that residents tend to think things like that won’t happen here.

According to archives, there have been two historical earthquakes in the region. In 1892, a magnitude 6 earthquake shook the town of Winter, west of Sacramento, and in 1975 Oroville was stuck by a 5.7 magnitude earthquake, both occurring on well-known fault lines located along the Sierra Nevada Mountain Range and the foothills of the coastal range.
