Digital camcorders and software programs can generate THM files, which are, essentially, thumbnail images of other media files. Typically, a THM file contains the first frame of the video file whose thumbnail it represents. The names of THM files are similar to the names of the underlying media files. THM files are based on the JPEG format and can be opened by the same programs that open JPEG files.
The most recent major earthquake occured near Haiti. Earthquakes occur most often in seismically active regions, most often the South Pacific around the so called Pacific Rinâ¦g of Fire, and any region where continental plates interact.
Mid-plate earthquakes -- those occurring in the interiors of plates -- are much less frequent than those along plate boundaries and more difficult to explain. Earthquakes along the Atlantic seaboard of the United States are most likely related in some way to the westward movement of the North American Plate away from the Mid-Atlantic Ridge, a continuing process begun with the break-up of Pangaea.
