The ARIA-EQ project: Advanced Rapid Imaging and Analysis for Earthquakes
Abstract
ARIA-EQ is a joint JPL/Caltech coordinated effort to automate geodetic imaging capabilities for hazard response and societal benefit. Over the past decade, space-based geodetic measurements such as InSAR and GPS have provided new assessment capabilities and situational awareness on the size and location of earthquakes following seismic disasters. Geodetic imaging's unique ability to capture the surface deformation in high spatial and temporal resolution allow us to resolve the fault geometry and slip that generated the earthquake in correspondingly high spatial & temporal detail. In addition, remote sensing with radar provides change detection and damage assessment capabilities that can image even at night or through clouds. However, since these data sets are still essentially hand-crafted, they are not generated rapidly and reliably enough to be useful for informing decision-making agencies and the public following an earthquake. We are building an end-to-end prototype geodetic imaging data system that would form the foundation for an envisioned operational hazard response center integrating InSAR, GPS, seismology, and modeling to deliver actionable science and situational awareness products. The automated geodetic imaging data system prototype is being realized by developing more robust analysis algorithms that capture the technical knowledge of technologists and scientists. Once developed, these algorithms will enable both the delivery of actionable products from larger data sets with enhanced modeling and interpretation, and the development of next generation techniques. We will present our progress to date on defining requirements, development of prototype data system and demonstration data products, and example responses we have run such as generating products for 2011 M9.0 Tohoku-oki M6.3 and Christchurch earthquakes.
