Ashtabula Earthquake Exercise

Ashtabula, Ohio, and surrounding communities were shaken by a 4.5 magnitude earthquake at 10:03 P.M. eastern time on Thursday, January 25, 2001. The event was felt throughout northern Ohio, western Pennsylvania, Michigan, and Ontario. Preliminary damage reports from Ashtabula indicated cracked plaster and masonry, walls bowed or moved, items knocked off shelves, and a ruptured natural gas line that resulted in evacuation of some residents. Graphs (a), (b), and (c) represent three seismograms from the events as recorded at Ashtabula, Lakeland, and Cleveland. Cleveland was farthest from the earthquake epicenter; Ashtabula was closest.

Describe how the seismograms differ, and identify and label each seismogram as Ashtabula, Lakeland, or Cleveland. Explain your answer.
