Browsing and Selecting
with the Event Trees
(QuakeExplorer
database)
The browsing and selecting of event hypocenters is performed in
hierarchical event trees
displayed in the left pane of QuakeExplorer. Several event trees types
are available, ordered by time, magnitude, depth, and either latitude/longitude or the results of a search.
The event trees contain
navigation nodes (
)
and event nodes (

- To select the event
tree type, click on the corresponding tree tab at the top of the event
tree pane.
- To expand a tree to the
next level below a navigation node, double click on the node, or single
click on the navigation handle to the left of the node.
- To fully expand all
levels of a tree below a navigation tree node, select the node, and
then, on the View menu, click Expand Fully.
