Better Hackathon 2020 ETHZ - Comparing Static And Dynamic Effects Of Earthquakes

Download to read offline

As part of the final BETTER Hackathon, project partners prepared 4 hackathon exercises. ETHZ organised this exercise as the challenge promoter for the Geohazards thematic area. This open exercise featured the use of Binder and purposely provided cloud resources but could also be run locally through a Docker image and Docker Compose. The focus of this half-day exercise was to find a convenient way of exploitation of Co-seismic interferograms, by using developed BETTER pipelines. The idea was to produce geocoded maps combining automatically the important results to have a convenient visualisation that helps interpreting results.Participants were expected to be familiar with the Jupyter environment (Python 3) and the most common EO libraries (e.g. GDAL). The recorded part includes the introduction of the exercise in the context of the BETTER project.

Better Hackathon 2020 ETHZ - Comparing Static And Dynamic Effects Of Earthquakes

  1. 1. Big-data Earth observation Technology and Tools Enhancing Research and development http://ec-better.eu This project has received funding from the European Union’s Horizon 2020 Research and Innovation Programme under grant agreement no 776280 Introduction to the Hackathon – ETHZ: Comparing static and dynamic effects of earthquakes on the ground surfaces Dr. Andrea Manconi (andrea.manconi@erdw.ethz.ch)
  2. 2. BETTER | Presentation • Main Objective: to develop a service layer able to deal with the Big Data challenges related to the use of Sentinel and Copernicus Earth Observation data. The development of this layer is driven by user needs gathered through DATA CHALLENGES, and delivering to them customized solutions denominated DATA PIPELINES • 6 partners: • Technical Development • Challenge promoters
  3. 3. From Challenge to Pipeline Data challenges are set by user communities to drive the development of the BETTER service layer • Challenge - a well defined problem that requires systematic processing of EO and/or non-EO data • 3 challenge yearly cycles • Promoters working in key societal areas • Involves high data volume and/or diversity • Centered in Copernicus and Sentinel data • 36 challenges were defined in the project, generating more than 100 output products for different AOIs around the world to support the activities of 10 different promoters
  4. 4. BETTER | ETHZ - Scope of the activities • GeoHazards - processes affecting the surface and/or subsurface of the Earth. Under this term are usually included earthquakes, volcanic activity, landslides, and land subsidence. ETHZ usually investigates GeoHazards with field investigations and in- situ instruments, and only in recent years the use of EO data has led to an increased capability of observing phenomena at regional scales. The main goal in BETTER is to facilitate a full exploitation the potential of EO with data mining approaches to better study and understand GeoHazards in different contexts. http://ec-better.eu
  5. 5. Analysis of the Surface Deformation associated with Earthquakes Damages produced by earthquakes are caused by permanent surface deformation due to fault offset, as well as dynamic shaking due to the pass of seismic waves. The investigation of the relationship between this two physical processes may provide a better understanding of earthquake hazard.
  6. 6. Analysis of the Surface Deformation associated with Earthquakes • The challenge ETHZ-01-01-03 aimed at producing a homogeneous catalog of co- seismic deformation associated with earthquakes with Magnitude larger than Mw 5 by relying on Sentinel-1. • The Sentinel-1 data processing is triggered by the information retrieved from the USGS pager, which for Mw>5 earthquakes usually include also a “ShakeMap” calculation . • Co-seismic interferograms are generated by the pipeline as soon as a new S1 image is available over the area identified as affected by the earthquake
  7. 7. http://ec-better.eu
  8. 8. Main goals of the ETHZ 2020 Hackathon Find a convenient/clever way to exploit the large amount of results obtained in the pipeline • Systematically generate a new high level product, i.e. a map combining the information provided by satellite radar interferometry (static displacement) and from ground seismic sensors (dynamic displacement)
  9. 9. Framework https://github.com/ec-better/hackathon-2020-ethz • 4 hours total time (13:30-17:30 CET) • Some examples of notebooks already available to facilitate the start up • 2 check-points (15:00 and 16:00 CET) for group discussion +Final review of the results at 17:00 CET • Channel for specific discussions (thematic and IT) : • https://meet.google.com/iox-xyej-gni
  10. 10. Enjoy! http://ec-better.eu
