Overall, the population in this region resides in structures that are vulnerable to earthquake shaking, though some resistant structures exist. On January 21, 1994 (UTC), a magnitude 6.9 earthquake 210 km South of this one struck Indonesia, with estimated population exposures of 32,000 at intensity IX or greater and 31,000 at intensity VIII, resulting in an estimated 7 fatalities.

PAGER results are generally available on the Internet within 30 minutes of the earthquake’s occurrence. However, information on the extent of shaking will be uncertain in the minutes and hours following and earthquake and typically improves as additional sensor data and reported intensities are acquired and incorporated into models of the earthquake's source. Users of PAGER estimates should account for uncertainty and always seek the most current PAGER release for any earthquake.
