This set of lists and maps provides information on the all earthquakes occurring in the world for the past seven days. The lists are organized by date, time, and magnitude; the interactive maps are organized by region. On the maps, symbols are coded by size (larger symbols mean greater magnitude) and by color (last hour, last day, last week). Clicking on individual map symbols links to detailed maps and written information for the selected earthquake, including date and time, location, depth, magnitude, and other data.
