Margaret Hopper provided these isoseismals after reexamining the intensity data and re-calculating the isoseismal contours. She generated isoseismal contours for each earthquake using computer contouring software, but adjusted positions of contours where, in her expert opinion, computer software had erroneously located them. Some isoseismals were unchanged from original authors and are referenced in her unpublished manuscript. Most isoseismals were changed to incorporate new information and to conform to common, modern, standards. The values for intensity reported in these data are consistent with the Modified Mercali Intensity (MMI) scale. This scale is useful 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 caused damage in the 4 - 8 range only. Intensity data are usually reported in Roman numerals, however Arabic numerals are used for computer accessibility. Each cover contains data for one or more earthquakes as follows: > Coverage Event Date Time Magnitude > i181112a December 16, 1811 at 0815 GMT; mag 8.1 > i181112b December 16, 1811 at 1415 GMT; mag 7.2 > i181201 January 23, 1812 at 1500 GMT; mag 7.8 > i181202 February 7, 1812 at 0945 GMT; mag 8.0 > i182707 July 5, 1827 at 1130 GMT; mag 4.8 > i183806 June 9, 1838 at 1445 GMT; mag 5.1 > i184301 January 5, 1843 at 0245 GMT; mag 6.5 > i185710 October 8, 1857 at 1000 GMT; mag 5.1 > i187609 September 25, 1876 at 0600 GMT; mag 4.5 > and 0615 GMT; mag 4.8 > i188301 January 11, 1883 at 0712 GMT; mag 4.6 > i188702 February 6, 1887 at 2215 GMT; mag 4.6 > i188708 August 2, 1887 at 1836 GMT; mag 4.9 > i189107 July 27, 1891 at 0228 GMT; mag 8.1 > i189109 September 27, 1891 at 0455 GMT; mag 5.5 > i189510 October 31, 1895 at 1008 GMT; mag 6.8 > i189904 April 30, 1899 at 0205 GMT; mag 4.9 > i190302 February 9, 1903 at 0021 GMT; mag 4.9 > i192211 November 27, 1922 at 0331 GMT; mag 4.4 > i192504 April 27, 1925 at 0405 GMT; mag 4.9 > i192509 September 2, 1925 at 1156 GMT; mag 4.6 > i193408 August 20, 1934 at 0047 GMT; mag 4.7 > i195811 November 8, 1958 at 0241 GMT; mag 4.4 > i196811 November 9, 1968 at 1701 GMT; mag 5.4 > i197404 April 3, 1974 at 2305 GMT; mag 4.3 > i198406 June 29, 1984 at 0758 GMT; mag 4.1 > i198706 June 10, 1987 at 2348 GMT; mag 5.0 Purpose: The data were generated to help in understanding the seismotectonic hazards in the vicinity of the lower Wabash Valley.

She provided hard-copy output on 8" x 10" paper. Contours were then digitized on an Altek digitizer table using Arc/Info. Arcs were edited and smoothed using grain, spline, and generalize.
