Using the Hazard Viewer to Compute a Forecast

The Nepal earthquake struck in a region with poorly constructed buildings, susceptible to major damage and destruction.  Here I show an illustration of how to use the Hazards Viewer to obtain a forecast.

The first step is to navigate to the viewer, then use either the circle selection radio button (shown) or the polygon selection tool.  Once the radio button is clicked, a dialog box appears and the radius of the desired circle can be entered.  Clicking "Enter" enables the circle to appear.  The yellow crosses can be used to resize or move the circle.  The actual forecast numbers are show at the lower left.
