You can use this gadget to monitor natural disasters around the world as published by the Global Disaster Alert and Coordination System (http://www.gdacs.org).
It shows the latest natural disasters like
earthquakes, volcano eruptions, tropical cyclones, and floods as color
coded icons with tool tips on a Google Maps backdrop; the icon colors
indicate the alert level - green, orange, and red. The icon will look
more transparent the older the event was published.
There is also a
list view which can be used to sort the natural disaster events
according to the date/time, region, and disaster type. Clicking on the
icon will bring up more details about the disaster event.
