I.
Retrieve a ShakeMap
HAZUS input file from ShakeMap Web Pages:
a.
From
the ShakeMap Web page (http://www.trinet.org/shake), select an earthquake of interest
either from the Map Archive or choose the most recent event. The Archive pages
contain HAZUS input files for historic and Scenario Earthquakes as well as recent
events. From the Web page specific to the earthquake of interest, select
Download, and select the “hazus.zip” file from the GIS Files
category. Choose a local directory and unzip this file to use the shapefiles
necessary for HAZUS input.
II.
Start HAZUS: Start > Programs > FEMA Risk
Assessment System >
HAZUS 99-SR1 for ArcView
III.
Create a New Study
Region (To open a Pre-Built Region Skip to III.)
|
a. Select - Region: Create - Type: New region and click OK. |
b.
Select the State to include in the region and click Next. |
|
|
|
|
c. Select the County to include in
the region and click Next.
(Note: by clicking on Map
the user can select the County from a map rather than selecting from the
list.) |
d. Select the Census Tracts to include in the region and click Finish. (Note: by clicking on Map button the user can select the Census Tracts from a map rather than selecting from the list.) (Note 2: the more census tracts that are selected the longer it will take to create the study region) |
|
|
|
|
e. Give the Study Region Name and click Ok.
|
f.
This is giving you the option to create the study region with the
supplemental multi-hazard data.
You will have the option to do this at a later time if you wish. If you choose to aggregate the data
you must have the supple-mental cds that were included in the HAZUS pack.
|
g. Skip to section IV.
IV. Open Pre-built region

Select the pre-built region you want to open and Click OK. Note: A newly imported region will
appear as the last name in the list of regions. |
