Abstract

We present an isoseismal map of the 17 August 1991 (Ms = 6.2) Honeydew earthquake and proposed modifications of the 1931 Modified Mercalli scale of Wood and Neumann to accurately estimate peak intensities for this earthquake and others in similar rural settings. Modifications introduced de-emphasize reliance on damage to masonry construction in assigning intensities and attempt to bring physical phenomena such as rockfall, landsliding, tree and limb fall, and water changes in line with the damage indicators.
