1 California Earthquake Early Warning System (CEEWS)

2 Background SB135 – Padilla Government Code Section 8587.8
Our Task Develop a comprehensive statewide earthquake early warning system in California through a public private partnership. Identify funding sources by January 1, 2016 Must not specify the General Fund as a funding source Approved by Governor Brown September 24, 2013

3 Goals and Objectives Today: Goal: ShakeMap in 5-10 minutes
Location Magnitude Ground shaking Goal: Provide advance notification tens of seconds before shaking People move to safe zone (under table) Slow and stop trains (BART, Metrolink) Isolate hazards (equipment, chemicals)

4 Objectives (Meets the intent of SB135)
Model: The state shall develop an EEW model that represents a public/private partnership, and a cost effective and reliable system. Management: The state shall formalize an EEW organization structure that incorporates existing roles and responsibilities, such as the CISN. Standards: The state shall have an approval mechanism to ensure appropriateness of EEW standards, how they apply to various EEW components, compliance and participation criteria. Education and Training: Cal OES shall convene a group of subject experts and stakeholders to develop and implement California’s EEW education and training. Funding: Cal OES will develop a distributed funding model.

5 How will we implement the system?

6 Build Upon CISN Earthquake notification system Within Seconds:
Provides detection, magnitude, depth, location and time Within Minutes: Provides worldwide earthquake coverage from global partners

7 Build Upon ShakeAlert

8 Define the System Scope
Outreach How Managed & Maintained Performance Requirements Features and Functions = $$$

9 Sensors and Telemetry Requires Uniform coverage along fault zones
Uniform station coverage Sustainable 24/7 operations Station coverage of km between stations is necessary for early warning km spacing is inadequate

10 When will implementation begin?
1 2 3 4

11 Cost Factors Initial Construction Costs
New or upgraded seismic stations & GPS stations Significant field telemetry upgrades Annual Operation and Maintenance Staffing for: Implementation and testing Operation and user outreach Continued Research and Development

12 “Advance notification occurs with CEEWS”
