Modified Mercalli intensities (MMI) for some earthquakes in eastern North America (ENA) and empirical MMI site corrections for towns in ENA

Bakun, W. H.; Johnston, A. C.; Hopper, M. G.

Abstract:

Modified Mercalli Intensity (MMI) assignments for earthquakes in eastern North America (ENA) were used by Bakun et al. (submitted) to develop a model for eastern North America for estimating the location and moment magnitude M of earthquakes from MMI observations. MMI assignments for most of the earthquakes considered by Bakun et al. (submitted) are published. MMI assignments for 6 other earthquakes used by Bakun et al. (submitted) are listed in this report: November 18, 1755 near Cape Ann, Massachusetts; January 5, 1843 near Marked Tree, Arkansas; October 31, 1895 in southern Illinois; November 18, 1929 on the Grand Banks, Newfoundland; September 26, 1990 in southeast Missouri; and May 4, 1991 near Risco, Missouri. MMI empirical site corrections developed and used by Bakun et al. (submitted) are also listed in this report.
