This presentation shows an FME workspace which reads USGS ShakeMap earthquake data from a geojson feed and clips California ZIP code boundary data to produce an output containing ZIP, City and MMI (shaking intensity) which is then automatically emailed to a list of recipients via FME Cloud.

3. Background
Insurance coverage for earthquake damage is not
covered by a homeowner (or renter, condo,
mobilehome) policy
California Earthquake Authority is a publically
managed, privately funded, non-profit insurance
company offering affordable earthquake coverage in
California
Set up in 1997 after the damaging effects of Loma
Prieta (1989) and Northridge (1994) earthquakes

4. USGS
ShakeMaps
ShakeMaps are
generated almost
immediately following
an earthquake
How do we
automatically retrieve
this information and
overlay with ZIP codes?

5. Requirements
• Automatically retrieve USGS ShakeMap data
immediately after an earthquake
• Overlay the ShakeMap and ZIP codes to
produce output containing ZIP code and it’s
corresponding MMI (shaking intensity) value
• Automatically email this result within minutes
of the earthquake

6. USGS notification email sent
to
usgsfeedreader@gmail.com
FME Cloud Service
Checks the email
account
every 15 minutes
Run FME
workspace to
retrieve ShakeMap
data and overlay
with ZIP codes
Keep
checking
every 15
minutes

new email?
No
Yes

7. Retrieve ShakeMap data
Write to an excel file
to email to recipients
Read the USGS
geojson earthquake
feed and test for
the following:
> = Mag 5
Yes
In California
No
Yes
Don’t need it
Don’t need it
California ZIP codes
CLIP
No
Workspace steps…..

8. Main point: FME rocks

9. Workspace

10. Step 1
• Read GeoJSON feed and
test the results
• FeatureReader looks at
GeoJSON ‘detail’ for
those that passed
Step 2
• Cleanup JSON
• Flatten ‘products’ expose
url for ShakeMap data
• Keep attributes for output

11. USGS ShakeMap with Modified Mercalli Intensity
ShakeMap for Napa/
American Canyon Earthquake
August 24th 2014
ShakeMap data, we are interested in
GRID_CODE in the MMI shapefile

12. Step 3
• Read ShakeMap
• Filter data, only MMI 5+
(Moderate Shaking) are
kept for the clipper
Step 4
• Clip California ZIP codes
• Use attribute pivoter to
keep only one row per ZIP
with Max MMI value

13. Step 5
• Output excel file
• One sheet per
earthquake!
• ZIP, City, MMI, ZIP type,
USGS ID
Step 6
• Generate Email
• Workspace runs in FME
Cloud, attaches excel file
and emails to recipient
list

14. Trigger
