What happens when I click on an earthquake?
When you click with your mouse on an earthquake displayed on one
of the zoomed-in maps, you will be sent to a page of text
information describing the parameters of that earthquake.
You can position your pointer anywhere on the visible surface
of an earthquake box -- which means that the text information
for an earthquake completely hidden behind another earthquake's
box is not accessible by clicking.
Sometimes a large earthquake will have many small aftershocks
located in the region about the mainshock, making it difficult
to select individual earthquakes in the cluster because of
overprinting of boxes. In this case, you can often find an
earthquake of interest by looking in the list under the map
and by comparing times, magnitudes, and locations.
The most recent earthquakes appear at the top of the list.
If you click on one of the blue triangles at the corners or edges
of a 2-degree zoomed-in map, you will be sent to the adjacent map
pointed to by the triangle.
