topics
Topics
  • ESC assistance for CalVO
    • NCSN – Long Valley seismicity, real-time HypoDD implemented, status of health software
    • Geodesy – monitoring inflation at Long Valley
    • California-wide permit with US Forest Service
  • Induced Seismicity – Oklahoma is #2 in seismicity
  • Funding Opportunity for VHP?
    • Volcanic ash hazard to Great Valley water delivery system
  • Earthquake Early Warning – impact on VHP

RealtimeHypoDD has been implemented in the NCSS AQMS processing system. Double difference solutions for events going back to 1984 and realtime events should be available at the NC Earthquake Data Center soon.

5837 earthquakes in FY13

Long Valley Caldera

Short and Long term monitoring

of changes in velocities with GPS

Last 2.75 yrs;

Inflation rate is significant

Last 2 Weeks;

no significant changes

Deformation of Long Valley Caldera since 1984 to the present using 2-color EDM and continuous GPS

Located 6.2km beneath resurgent dome

Located ~12km beneath (or south) caldera’s south moat

tephra volcanic ash localities
Tephra (Volcanic Ash) Localities

27 of 128 CDWR borehole localities so far have encountered tephra of variable thickness (0.1 to 7.5 m; 1.9±1.7 m)

Four distinct ashes identified at 27 localities

Unnamed Ash (180-210 ka)

delta tephra primarily transported and deposited by pleistocene great valley rivers

ShakeAlert Technical Implementation Plan

Goal: build & operate a West Coast EEW system to…

  • Issue public warningsfor large earthquakes and…
  • Send warning parameters to government and private sector users…
  • …as soon as ShakeAlert meets quality and reliability standards on a region by region basis

Progress Toward a Public EEW System
  • Evolutionary Approach
    • 2006-now – R & D phase
    • Jan. 2012 – Demonstration System Live
    • 2014 – Production Prototype
    • ?* – Limited Regional Rollout
    • ?* – Full Operation
