Abstract

We combine newspaper accounts and Nuttli's (1976) isoseismal map to assign modified Mercalli intensity (MMI) at 76 towns for the May 16, 1909 Northern Plains earthquake. The earthquake was felt across more than 1,500,000 km2 in the States of Minnesota, Montana, North Dakota, South Dakota, and Wyoming and the Provinces of Alberta, Manitoba, Ontario, and Saskatchewan.
