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
