Reliable Delivery of Real-time Earthquake Hazards Information to Critical User
The California Integrated Seismic Network (CISN) has collaborated to develop a next-generation earthquake notification system. The CISN Display will graphically alert users, in near real-time, of seismicity as well as vital earthquake-hazards information following a significant earthquake. This program suite is expected to provide emergency managers, and other decision makers with the information and tools necessary to effectively deploy limited personnel and resources in support of recovery efforts after a major earthquake. This effort helps fulfill a CISN mandate: to disseminate earthquake information in support of public safety, emergency response, and loss mitigation. This software architecture includes a client GUI known as the CISN Display, a server module identified as the QuakeWatch Server, and the messaging middleware supporting an XML messaging schema.

Real-time Earthquake Display
Primary to the CISN Display’s operation is its active monitoring of near real-time seismicity, and other geo-hazards information. Newly received messages and updates are immediately posted to the screen. Virtually all user functionality previously available in CUBE/REDI has been replicated in the CISN Display. However, the new client also boasts a number of upgrades that enhance its functionality as well as its reliability and robustness. New improvements include stateful connectivity, fail-over capability, data persistence, platform independence, a highly configurable graphical-interface and modular software architecture. These design improvements combine to form the basis of a highly scalable client, and introduce a new level of reliability and application robustness not previously available.
Gateway to Other Earthquake Products
A secondary, but equally important function of the CISN Display is its service as a Web-portal to all relevant earthquake hazards information produced after a large earthquake. Web-based products currently available for delivery are ShakeMap, HAZUS Input files, Felt Reports, Focal Mechanisms, Waveform Images, Aftershock Forecasts, Tsunami Warnings and more. URLs to these and other Internet products are automatically created on the CISN Display and made available so users have quick access to crucial decision-making information. In the case of ShakeMap, a behavior may be selected by the user to automatically display the ShakeMap in a separate browser window as soon as it becomes available on the Web. This distribution system will help promote future online tools and services since they can be rapidly distributed and made available to critical users everywhere.
GIS Mapping Capabilities
To provide critical users a means of visually performing initial assessments of potentially damaged infrastructures, a GIS mapping engine has been integrated into the CISN Display. Thanks to the OpenMap project the client interface is able to plot many popular formats of GIS vector-layers. This allows users to make quick and reasonable assessments of vital infrastructure, when viewed alongside earthquake hazards information such as ShakeMap. In addition to geo-political boundaries as with state and county lines, imported GIS graphics may also represent roadways, airports, railroads, bridges and other public lifelines vulnerable to earthquake damage. In essence this mapping feature allows each organization to customize the application interface specific to their operation’s needs. Additionally, users can now have ShakeMap shape files automatically downloaded and plotted directly onto the CISN Display map. This added behavior was a direct result of beta-tester feedback, and illustrates the collaborative approach taken in user-participation development.

Interested users will be asked to register their organization to access to the software. Users will create an account profile and provide basic contact information. User requests will be approved per the current CISN Access Policy.
CISN Display is a cooperative project between OES, Caltech, CGS, UCB and the USGS. Funding for the project comes from the OES, USGS, FEMA/OES Hazards Mitigation Grants Program, Emergency Management Performance Grant Programs, and the National Tsunami Hazards Mitigation Program of NOAA. Additional financial support was provided by ISTI; developers of the CISN Display and other custom software solutions.
