Near Real-Time Earthquake Catalog for the Endeavour Segment of the Juan De Fuca Ridge: Integrating Community Code Into Ocean Networks Canada's Ocean 3.0 Data Portal
Description:
Ocean Networks Canada’s NEPTUNE observatory consists of an 800 km fiber-optic cable loop that provides power and real-time communication to a network of Ocean Bottom Seismometers (OBS) offshore Vancouver Island. The network covers the northern end of the Cascadia Subduction Zone, the abyssal plain of the Cascadia Basin, and extends all the way out to the Endeavour Segment of the Juan De Fuca Ridge. Community members Zoe Krauss and William Wilcock developed a sophisticated software package that includes components programmed in Matlab, Python, and Fortran, which they used to create a long-term micro-earthquake catalog for the Endeavour Segment, constructed from OBS observations spanning nearly three decades. The catalog includes the last rupture of the Endeavour Segment that took place via a sequence of dike emplacements between 1999 and 2005. Since 2016, the earthquake catalog data were obtained from a small network of 3-5 cabled OBS directly on top of the ridge that are connected to the NEPTUNE observatory. The waveform data are publicly available through the Seismological Facility for the Advancement of Geoscience (SAGE/IRIS) under the network code NV and near-real-time updates of the catalog are made available at http://endeavour.ocean.washington.edu by the authors of the code.
This presentation shows how we plan to integrate user community provided code into Ocean Networks Canada’s Oceans 3.0 Data Portal and run it in an operational environment. We will use the code to generate the Endeavour earthquake catalog as a test case and provide details about the system requirements, different design options, and compare the approach to our existing catalog of Earthquake Early Warning detections. Once integrated, the real-time catalog will provide context for non-seismologists looking at other measurements of the hydrothermal system that are available through Oceans 3.0. This catalog development is timely since an increase in seismic activity hints to a new rupture in the not too distant future.
