2019 SSA SIG Survey Results on Rapid Response

On April 26, 2019, IRIS hosted a special interest group (SIG) meeting to survey the community on their scientific interests and instrumentation needs related to responding rapidly to geohazards (large earthquakes, volcanic eruptions, landslides, etc.).  An interactive polling tool (VoxVote) was used at the SIG to allow participants to respond to questions using their wifi-enabled devices.  We have tabulated the results of the survey, and present them here for public review.

Survey Statistics

  • Our SIG survey had 108 unique participants
  • A total of 2,410 votes were submitted across 17 science questions
  • Only 3 questions were single choice, all others were multiple choice

Survey Findings (high-level)

  • Earthquakes/aftershocks remain the most popular rapid response target.
  • Only 1/3 of participants say that the current PASSCAL inventory is meeting their current rapid response needs.  The remainder want some combination of more instruments, different instruments, or faster delivery of instruments.
  • When asked about desired seismic instrumentation, 33% asked for broadbands, followed by 25% each for strong motion and nodes.  Short periods were requested by 15%.
  • About 40% of participants said they'd like to deploy between 10-25 seismic stations for their rapid deployment.  33% said they'd like to deploy 100 or more.
  • The most popular deployment durations were: months (35%), years (28.7%), and weeks (22.4%)
  • The most requested non-seismic instrumentation for rapid response deployments was geodetic, followed by fiber optics, LiDAR, and infrasound.
  • Respondents were equally split on whether the facility should prioritize: 1. aadding more instruments, 2. minimizing deployment logistics, or 3. lowering power requirements.
  • More than half of participants said they only wanted field support during deployment, and nearly a third said they needed no field support at all.
  • Telemetry was required by 37% of participants, but even more (49%) said they'd consider it if the cost was reasonable.  Of those wanting telemetry, about half wanted real-time data monitoring capabilities opposed to just state of health or triggered events.
  • 82% of participants say they wanted to deploy within the first few days after a geohazard event occurs (30% within hours)
  • The largest limiting factor for rapid deployments was access to funding (42.5%) followed by access to the right instrumentation (31%).
