Tilt/Vertical Change Map
Description
Tilt is the change of slope that can affect water distribution, drainage, and sewage
services. These maps are generated from Disloc surface deformation modeling code
and iteratively refined using geodetic data from GPS model solutions.
Use for decision making
When deformation changes the tilt of essentially flat ground or increases slopes that
may be near the angle of repose, drainage or water conveyance may be affected and
landslides may result. Maps can be paired with infrastructure data layers to assess
where likely damage has occurred and aid with allocating resources.

Strain Magnitude Map
Description
Deformation strain magnitude is a measure of the concentration of local relative
changes in the surface shape, and so can identify locations of potential fault surface
rupture as well as locations where infrastructure may be dangerously stressed by
tension, compression, or shear of the surface materials. These maps are generated
from Disloc surface deformation modeling code and iteratively refined using
geodetic data from GPS model solutions.
Use for decision making
Where deformation gradients are high, large motions may have occurred, disrupting
infrastructure and potentially causing greater damage. Maps can be paired with
infrastructure data layers to assess where likely damage has occurred and aid with
allocating resources.

Aftershock Forecasts
Description
ETAS type forecast based on aftershock scaling relations intended to provide
estimates of aftershock activity following a large mainshock. In our automated,
web-service implementation, spatial and temporal distributions of aftershocks are
determined from earthquake scaling relations and the orientation of the rupture is
determined by local seismicity. This approach facilitates fast and objective
computation of aftershock properties. By mitigating “expert” subjectivity,
automating the effective removal of small magnitude, distant earthquakes by Omori
and spatial decay functions, and by estimating each earthquake's ETAS contribution
from its rupture properties, this method facilitates the use of large (5+ years)
regional catalogs. Moreover, a forecast can be run quickly, or even automatically
triggered, in response to a large earthquake, and because the orientation of each
earthquake is determined from local seismicity, the forecast evolves, presumably to
a state of greater accuracy, as the aftershock sequence progresses.
Use for decision making
Provides forecasting method that can be calculated quickly and updated regularly
during a response with minimal user input. Forecasts are generated in KMZ output
that are easily interpreted (areas of higher likelihood in warmer colors, lower
likelihood in cooler colors).

Infrastructure Database Service
Description
Locating and identifying critical assets that may have been exposed to damage after
an earthquake, such as dams, freeway bridges, schools, police and fire stations,
hospitals and other high priority targets, provides essential information for decision
markers for response efforts. The FEMA HAZUS-MH data inventory includes a large
amount of critical infrastructure data covering every state in United States. EDECIDER provides an OGC-compatible KML-generating service that delivers near 30
HAZUS-MH information layers within a user-specified radius from an
epicenter. This database is being expanded to include HSIP Freedom data and we
are exploring incorporating HSIP Gold data.
Use for decision making
Infrastructure layers may be overlaid onto other information layers to identify what
structures may have been potentially exposed to damage due to an earthquake or
other emergency incident. Advanced spatial query support has been added to the
database service, which provides FEMA critical infrastructure information to a
broader range of emergency situations. The geometry of an incident falls into three
types: point (e.g earthquake), line (e.g tornado), and polygon (e.g flood, wildfire).
Users can specify the search distance (buffer zone) and the types of critical assets
for different incidents.
Data Availability

incident adapter under development.
