Goals and Objectives
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)
Today: ShakeMap in 5-10 minutes•Location•Magnitude•Ground shaking

Objectives(Meets the intent of SB135)
1.Model: The state shall develop an EEW model that represents a public/private partnership, and a cost effective and reliable system.
2.Management: The state shall formalize an EEW organization structure that incorporates existing roles and responsibilities, such as the CISN.
3.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.
4.Education and Training: Cal OES shall convene a group of subject experts and stakeholders to develop and implement California’s EEW education and training.
5.Funding: Cal OES will develop a distributed funding model.

Build Upon CISN
Earthquake notification system
•Within Seconds:
Provides detection, magnitude, depth, location and time
•Within 15-30 Minutes:
Provides worldwide earthquake coverage from global partners
