Overall, the population in this region resides in structures that are resistant to earthquake shaking, though some vulnerable structures exist. A magnitude 5.2 earthquake occurred near the Whittier Narrows, California, region 21 km northeast of the location of this earthquake on October 4, 1987 (UTC), with estimated population exposures of 477,000 at intensity VII and 2,994,000 at intensity VI, resulting in an estimated 1 fatality. On January 17, 1994 (UTC), a magnitude 6.7 earthquake occurred near the Northridge, California, region 32 km northwest of the location of this earthquake, with estimated population exposures of 73,000 at intensity IX or greater and 2,181,000 at intensity VIII, resulting in an estimated 33 fatalities. Recent earthquakes in this area have caused, landslides and liquefaction that may have contributed to losses. [Source: USGS – Earthquake Hazard Program]
