Seismic Monitor allows you to monitor global earthquakes in near real-time, visit seismic stations around the world, and search the web for earthquake or region-related information. You can also view seismograms and make dataset requests via its WILBER interface. The date and time of the map (in Universal Time) are located in the lower right hand corner. Earthquakes are shown as colored circles, where the size of the circle tells you the magnitude of the quake, using the legend at the top left of the map. Only earthquakes of magnitude 4.0 or greater are displayed. Age of Earthquake: the last 24 hours, from 24 to 48 hours, from 3 days to 2 weeks, and from 2 weeks up to 5 years. The distribution of earthquakes over the past 5 years is represented by the purple dots and demonstrates how earthquakes define the boundaries of tectonic plates, as well as the relationship between topography and earthquakes. The Earth's shadow shows the line between day and night as well as the progression of the seasons. This has been added to my comprehensive listing of December 26, 2004 Asian Tsunami Information and Stories available by clicking here.
