[email protected]. Structural Geology of the Moodus Seismic area, south-central Connecticut by P.J. Barosh, Weston Observatory, Boston College, David London, University of Oklahoma, and Jelle de Boer, Wesleyan University INTRODUCTION * w The area around Moodus, Connecticut (fig. 1) is one of the most contin uously seismically active places in the northeastern United States. Indian legends from pre-colonial times noted the area for its earthquakes. The name Moodus is derived from the Indian name Morehemoodus meaning "place of noises" (Chapman, 1840). The earthquakes are very shallow, and are accompanied by "noises": rumb ling and booming sounds (Ebel and others, 1982) created when the high fre quency vibrations of the ground couple with the atmosphere. Earthquakes of less than magnitude 1 have been felt and ones as small as magnitude 0 have been heard (Ebel and others, 1982).
