Catastrophic events

Historical Earthquakes: Fascinating collection of historical images (875 slides) of earthquakes presented by countries or regions, or through a chronological list of events. Includes a bibliography. It is based on the collection of Dr. Jan Kozak, a geoscientist at the Institute of Rock Structures and Mechanics in Prague, Czech Republic, and Katherine Frohmberg at the Earth Sciences Library of the University of Berkeley, USA. The historical prints and illustrations from many countries illustrate the wide range of human reactions - often linked with religious beliefs and folklore - to earthquakes and other natural disasters.

Monitoring Earthquakes using InSAR: Thanks to a powerful new technology, called Satellite Radar Interferometry (or InSAR for short), researchers are now able to reveal bulges in our planet. By using radar signals from satellites to measure the up and down movement of the Earth's crust at an unprecedented level of accuracy, they can measure changes in elevation on the order of 0.508 to 1.016 cm over areas hundreds of square meters wide. A nice thing about InSAR is that it does not need equipment on the ground and so can reveal movements of magma (related to earthquakes and volcanic eruptions) in the remotest areas of the planet. InSAR can also map land subsidence, that is, the sinking of the Earth surface following the removal of oil, gas or water. For a detailed insight on recent applications of InSAR to earthquake monitoring, a look at various papers, such as that by Tim Wright on the Izmit (Turkey) earthquake or that by Charles Wick on seismic deformations in east central California is much recommended.

Everything you ever wanted to know about Tsunamis:
Developed by the Pacific Tsunami Museum, this site provides the basics about what tsunamis are, what is known about them, and also provides links to other tsunami websites as well as references for further information.
L ooking for some historical information about the Big Wave ? then click here, where you will find information on tsunami events from 49 B.C. to the present in the Mediterranean and Caribbean Seas, and in the Atlantic, Indian, and Pacific Oceans. The 'Run-up' database contains information on locations were tsunami effects have occurred.
N eed to know what is real and what is not about tsunami myths ? then go to the site developed by The Tsunami Society whose mission is to disseminate factual information about tsunamis. This puts to rest the much hyped 'Mega Tsunami' thesis.
L ast but not least the Australian Spaceguard Survey, gives you a detailed look at Tsunamis as the result of an asteroid or comet impact. You can find the number asteroids impacts with earth, number of Tsunamis generated by impacts along with risk estimates
