Abstract
The maximum ground acceleration is the largest ground acceleration recorded in the region due to the earthquake. The value of risk of earthquake ground acceleration is needed to be considered as part of the planning of earthquake resistance building. Risk is the product of hazard multiply by vulnerability which the result depend on both factors. Disaster potential is the ground acceleration factor, while the vulnerability is a total population factor. Using historical earthquake data from USGS in North Sumatra which located at 1ºS - 5ºN and 96.5 - 100,5ºE, period from 2005 to 2014 calculated the maximum ground acceleration with formula Boore (1997). The value is 372.5 gal. Medan and Deli Serdang have the largest population of the North Sumatra Province, it is referring that the greatest risk produced by the greatest vulnerability factor
