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.
How Earthquakes Happen. An aerial view of the San Andreas fault in the Carrizo Plain, Central California. An earthquake is the vibration, sometimes violent, of the Earth's surface that follows a release of energy in the Earth's crust.This energy can be generated by a sudden dislocation of segments of the crust, by a volcanic eruption, or event by manmade explosions.eologists have found that earthquakes tend to reoccur along faults, which reflect zones of weakness in the Earth's crust. Even if a fault zone has recently experienced an earthquake, however, there is no guarantee that all the stress has been relieved. Another earthquake could still occur.
