Summary

This cover contains locations with intensity values associatedwith felt reports from damaging earthquakes in the lower WabashValley occurring from 1811 through 1987. Margaret Hopper collatedthese data from historical data gathered from previousresearchers, personal letters, newspaper accounts, officialcorrespondence, and from mailed responses to queries on damageeffects from modern earthquakes. She examined all reports andassigned a Modified Mercali Intensity (MMI) value to each report.The values for intensity reported in these data are consistentwith the MMI scale used for describing damage from earthquakes.For historical earthquakes, these values are gathered in the 4 -10 range. In the central U.S., historical earthquakes have causeddamage [...]
