2 EEWS Programme University of British Columbia Earthquakes 101 Network of Seismic Sensors UBC Technology, Server, Software, Maintenance Typical Parish & School EEWS Installation Budgets Questions Filename, 2

3 Earthquake Warning System for BC Objective: To provide a network enabled EEWS for all of BC, which will eventually be integrated with the Western Sea Board of North America Prof. Carlos E. Ventura University of British Columbia Filename, 3

4 Plate Tectonics Filename, 4

5 Average Annual Global Frequency of EQs Filename, 5

6 Cascadia Seismic Sources Crustal EQs Subcrustal EQs Subduction EQs Filename, 6

7 Fundamental idea of Earthquake Early Warning Rapid event detection - Few seconds to few tens of seconds Event characterization from early data (P-wave detection) Dissemination of warning ahead of shaking Both automatic and human-mediated responses Filename, 7

8 Earthquake Early Warning (EEW) First Concept: to use instruments that are more sensitive than human to warn of oncoming seismic waves Second Concept: to use network of sensors that are far away to warn of coming waves. In general for an earthquake: Fault ruptures A fast-moving pressure wave (P-Wave) moves through the earth and reaches the receiver first. Sensor will sort through the constant ongoing noise and determine, is this is an earthquake? More damaging shear-waves (S-Waves) come after. Can be 5 to 20 seconds warning? Networked sensors can add warning time: few seconds to few tens of seconds Filename, 8

9 Where is EEW used? Learning about EEW in Japan Filename, 9

10 BC Earthquake Early Warning Network (BCEEWN) Project A network of sensors to improve earthquake early warning Started as a collaborative effort between UBC/BCMoT/BCMEd/RCAV/GSC (PGC) Added benefit: Additional warning time! Filename, 10

11 UBC TETRA Sensor for EEW A sensor for Seismic Early Warning & Strong Ground motion State-of-the-art technology specifically developed for BC Internet-based system High sensitivity, self-orienting, programmable Can be used above and below ground, and underwater Can measure ground shaking, magnetism & temperature Filename, 11

12 RCAV Earthquake Early Warning System Project Pilot project Filename, 12

13 Typical Site / School Installation NETWORK LINKS TO OTHER PWave MONITORING & ALARM ONLY SITES SIREN WebRelay BUILDING with-out P-Wave Sensors INTERNET CONNECTION MECHANICAL GAS EARTHQUAKE SHUT- OFF VALVE SIREN SIREN EWS CONTROLLER /RECORDER BUILDING with P-Wave CONTOLLER INTERNET CONNECTION MECHANICAL GAS EARTHQUAKE SHUT-OFF VALVE GAS METER UBC FIELD ACCELEROMETERS IN ENCLOSURES BURRIED IN GROUND EARTHQUAKE EARLY WARNING SYSTEM DIAGRAM Filename, 13

14 Filename, 14 Site Installation - Tetras

15 Trenching Trenching is required to link the Tetras back to the school Trenches dug ~8 deep Cables installed Warning tape placed near surface Surface refinished Filename, 15

16 Alarms If possible School PA system will be integrated to be used as the alarm Otherwise a School will have sirens installed Some schools need to be tested for adequate volume levels All alarm controls need access to the internet PA systems and/or Sirens provide for the early warning alarm. Unique identifiable message or sound Filename, 16

17 Typical Site / School Installation Prime Node Site: 2 Tetra Sensors, min of 100 ft. apart outside of main building Trenching from Tetras and cabling to the Computer Server/ Internet supply point. Tetra & Siren Relay Controller (Box) Integration with Public Address System (if possible) Sirens Large Groups of Classrooms Sirens Small Gymnasiums, Isolated Classrooms; Band Rooms Filename, 17

18 TRAINING PROGRAM PRINCIPALS & KEY STAFF Training is simple and can be done remotely Earthquake 101 AND EEWS School Training» What to do when P-Wave Siren Sounds» Added Emergency Protocol for EEWS P-Wave Demonstration Training Tool Kit (optional Extra) LED Strip Software Demo Kit Filename, 18

19 Financial Cost Components: Overall Project Direction, Project Financials and Costing; Contracts; Purchase Orders: Recommendations to Owner Vendor Payments (Project Leader Jim Radford) UBC Technology, Software, Instrumentation, Server and Networking, Region advanced warning (incl Neptune System) ( Dr Carlos Ventura; UBC: Tetras & Enclosures manufacture & install, Geotech and Drilling Installations (Team of four to site for 2-3 days) Site Project Management, Planning, BC One Call, Site Design, PA integration, Siren Testing, Cost Estimate, Order, IT EEWS upgrade, Internet Testing; As-Constructed details (Quicklink) Site Siren Testing, Equipment Supply, Install; IT upgrade; As- Constructed details (Contractor Team of 3-4 to site - 7 days, local civil trenching, surface repairs) Ongoing Annual Maintenance Contract and System monitoring (UBC and Quicklink) Client responsible for Financial Plan, Annual Maintenance with UBC and system monitoring Filename, 19

20 Summary of Budget Costs Budget Costs: Initial costs would be borne by the sponsoring body e.g. Veritas School and Sacred Heart Parish Budget amount = $60,000 Other alarm only sites can then be added to the EEWS at a Budget amount = $30,000 Of this amount, approximately $10,000 would be paid back to the contributing control site. Example: Initial sponsoring site: $ 60,000 Say 11 other schools: $330,000 $390,000 of which $110,000 would be paid back to the Sponsor Filename, 20
