Past earthquakes here. A magnitude 6.9 earthquake 150 km sw of this event struck UK on January 21, 1994 (UTC), with estimated population exposures of 28,000 at intensity VIII and 28,000 at intensity IX or greater, resulting in a reported 7 fatalities.
Local buildings. Overall, the population in this region resides in structures that are vulnerable to earthquake shaking, though resistant structures exist. The predominant vulnerable building types are unreinforced brick with concrete floor and precast concrete frame with wall construction.
Population and intensity modelled by USGS PAGER. Estimates, not a count of people affected.
