Site of the Day for Wednesday, January 5, 2005 Warning of Tsunamis Today's site from the Why Files offers a brief but informative look at tsunami warning systems. Gentle Subscribers will find an overview of how such a system works and the proposals to establish on in the southern Pacific. "A series of Pacific Ocean tsunamis over the last century fueled the establishment of an ocean-wide warning network. But the Indian Ocean, where tsunamis are less common, has no such system. ... officials in several nations [have] started discussing a warning network for the Indian Ocean." - from the website The web page provides a summary of the components of a tsunami warning system, the equipment required and highlights the fact that the most serious problem for any warning system is the logistics of evacuation. An annotated graphic of the seismometer readings on Guam, for December 26, displays a timeline of the wave compression. Additional information on the current tsunami warning system in the North Pacific is available from links on the page.
