Earthquake and Tsunami

The Earthquake and Tsunami large scale pilot is about building with LEXIS a time-constrained HPC emergency response simulation and decision support flow. It combine:

  • Fast, rough on-line simulations, giving immediate, but only approximate, results
  • Accurate compute intensive simulations, giving iteratively more and more precise results about the extent and damage
  • Offline scenario data, pre-computed scenarios to be used by experts as support for decision making
  • Time-constrained flow control, ensuring that at pre-set deadlines, the flow provides the best information it has computed so far
  • Live updates, so that both background information and new, ground or sensor information is immediately propagated into the flow. External data sources (remote sensing) will also be called upon in the process, both on flow outcomes and as flow inputs.
  • Emergency support data products processing; maps, damage and loss estimates.

This pilot brings together among the best components in the field, covering:

  • Tsunami simulations: on-line, on-time precise simulations with TsunAWI
  • Damage exposure and estimate with OpenBuildingMap
  • Time constrained HPC / Data workflow: the ability to express time constraints at which point preliminary data must be made available
  • Data exchanges: the ability to acquire data, and to deliver data products on time: warnings, estimates, maps
  • Optimisation: analysis and deployment of optimisation techniques to improve the ability of the system to provide accurate decision support on time.
  • Infrastructure: on the LEXIS technology and interfaces, and as a mapping on HPC and cloud resources.

Pilot results will be used to enhance the existing natural disaster warning and emergency response system in place after the 2004 Tsunami, InaTEWS.
