PRINT THIS STORY Dennis "Chuck" DeMets 'Takes Five' Studying the Earth's powerful forces Posted: Dec. 27, 2004 A series of earthquake-generated tsunamis - massive tidal waves - radiated across the Indian Ocean on Sunday, killing more than 20,000 people. Dennis "Chuck" DeMets, professor of geology and geophysics at the University of Wisconsin-Madison, talked about these killer waves with Journal Sentinel science reporter Susanne Quick. Advertisement Q. What kinds of geological forces can cause a tsunami? A. There are three types of geological occurrences that can cause a tsunami. The first is a particular type of earthquake in which there is a substantial movement of crust underneath the water. This will induce a wave on the surface. The second, a volcanic eruption underneath the water. And third, a large landslide that slips into the water. Q. What triggered the recent giant waves in Asia?

A tsunami is a series of very long wavelength ocean waves caused by the sudden displacement of water by earthquakes, landslides, or submarine slumps. Ordinarily, tsunamis are produced only by earthquakes exceeding magnitude 7.5 . In the open ocean, tsunami waves travel at speeds of 600-800 kilometers per hour, but their wave heights are usually only a few centimeters. As they approach shallow water near a coast, tsunami waves travel more slowly, but their wave heights may increase to many meters, and thus they can become very destructive.

THE ATJ DOLLAR COLLECTION The seismological and other collections of Dr ATJ Dollar, held in the National Seismological Archive (NSA), have been examined and catalogued as part of an NSA initiative on the study of the history of seismology. The Adobe Acrobat PDF version of the report on this project can be downloaded from the foot of this page, or from the NSA reports page A.T.John Dollar (1908-1981) graduated in geology from King's College, London in 1931, and moved to Emmanuel College, Cambridge, where, supervised by CE Tilley, he gained his PhD on the petrology and structure of Lundy. In 1935 he became a Research Fellow at Emmanuel, and after a brief period at St Andrews University moved to Glasgow University in 1939. War service interrupted his tenure there, then, in 1950 Dollar became head of the Geology Department at Birkbeck College, and remained there until his retirement. During his academic career, Dollar developed interests in many subjects. His collected papers reflect these interests, and contain material on volcanology (including photos and articles on Surtsey, Jan Mayen, Iceland, Hawaii and various Pacific Islands), tsunamis, geology (especially of the southwest peninsula and Lundy), landslips, seismology and seismotectonics. He was largely responsible for the installation of a Jaggar Recorder at Comrie, Perthshire in 1938, and was particularly interested in the Great Glen and its supposed seismicity. Dollar wanted instrumentation on both sides of the fault, and was keen to site a seismograph at Fort Augustus Abbey. He also invented a clinometer, and various accessories for petrological microscopes.

Miller , January 2005 UPDATE (June 2005): Wondering how far the tsunami went inland? I have a short followup about that. The day of the Indian Ocean earthquake and tsunami on December 26, 2004, I started posting entries to my journal that drew on the oceanography training from my degree in marine biology, my online research and writing skills, and an interest in tsunamis I'd had since writing a research paper on them a decade and a half earlier. For the next several weeks, I wrote quite a bit on the subject. Image and animation from NOAA , January 2005.

Don't forget too that, while tsunami victims need assistance desperately, there are also many other people suffering around the world, from Africa to your home town, and donations can help them as well. Contents Back to top My weblog entries about tsunamis became quite popular in the aftermath of the disaster, attracting hundreds of people a day from all over the world. Some visitors asked questions, and I answered them as best I could in subsequent postings. I've put them all together here and edited them for a better flow in order to make everything I wrote available in one place. They appear in chronological order, with the oldest (from the day of the tsunami) first:

Some Interesting Websites Introduction When the Shoemaker-Levy 9 comet hit the planet Jupiter in 1994 the heat released could be detected by astronomers on Earth. It is thought that throughout Earth's history, there have been similar impacts by various comets and asteroids . The best documented case of recent years occured in 1908, when the Tunguska comet exploded just prior to an impact in Siberia, causing destruction over an area approximately 30km in diameter. In photographs of the moon it is often quite easy to pick out the circular depressions which are thought to be a result of impacts. On Earth, such craters are more difficult to identify due to the effects of erosion and weathering, cover by vegetation or younger rocks and the destructive effect of plate tectonics . However, impact craters can be identified by consideration of not only their shape, but also by unique geological, chemical and physical characteristics. To date, approximately 150 impact structures have been identified on Earth's surface. These have often been identified using

99. Tsunamis bay that forces tsunamis to awesome heights (McGeary, Plummer PhysicalGeology (1992). In depth background discussion on tsunamis in the Pacific http://www.geo.mtu.edu/department/classes/ge404/tsunami/

Tsunamis are commonly refered to as tidal waves, harbor waves, and seismic sea waves. They are usually caused by earthquakes beneath the ocean surface but, can also occur due to submarine landslides or volcanic eruptions. These physical distrubances propagate long low waves which relates to small amplitudes and broad wavelengths. Waves heights ranging from 1-30 meters are fairly common but extreme cases such as Ryukyu islands (south of Japan)have experienced waves of up to 85 meters. At this proportion, these waves could have a devasting impact on a large area of land. Tsumanis are unlike ordinary water waves on the ocean surface. "A large wind-generated wave may have a wavelength of 400m and be moving in deep water at a speed of 90km/hr. The wave height when it breaks on shore may be only .6 to 3m. Although in the middle of hurricanes the waves can be more than 15m high. A tsunami, however, may have a wavelength of 160km, and may be moving at 725km. In deep water the wave height may be only .6 to 2m, but near shore the tsunami may peak up to heights of 15 to 30m. This great increase in wave height near shore is caused by bottom topography; only a few localities have the combination of gently sloping offshore shelf and funnel-shaped bay that forces tsunamis to awesome heights"(McGeary, Plummer Physical Geology (1992).

Guest Writings Tsunami: Geology of Genocide By Satya Sagar 26 December 2004. It was the day Geology committed Genocide. For millions of people along the coastal regions of South and Southeast Asia the morning had begun like any other passing day, a step closer to the end of the old year and the beginning of a new one. Very soon though, both Earth and Ocean had conspired to take all of them to the very end of their world, initiating the greatest natural disaster in recent human history. First came a great quake that made the entire globe tremble. Next, Tsunami waves several meters high, that destroyed everything in their path, leaving thousands upon thousands dead across half a dozen countries. Men, women, children- swept from their homes and swallowed by raging seawater. Homes, cars and even a train plucked and tossed about like toys before being smashed to pieces. Most human societies cope with the loss of loved ones by drawing upon tradition and ritual to drown out their sorrows. The scale of the tragedy wrought by last Sunday’s deadly duo of tremor and tsunamis was such it made all conventional mourning meaningless - for no one knows where to begin or where to end.
