The Photonic Seismology Lab,
Tel Aviv University
Research on Microseismic Event Location Presented at IGS 2026
February 2026
We are pleased to share that members of the Photonic Seismology Lab from the Department of Geophysics at Tel Aviv University traveled to Kfar Blum this week to attend the Israel Geological Society (IGS) 2026 conference. The lab was represented by our head, Dr. Ariel Lellouch, alongside MSc student Uri Wygodny and PhD student Aleksei Nelaev.
The highlight of our trip was the poster presentation delivered by Uri, which showcased innovative seismic analysis methods developed within our team. The presentation, titled "Picking-free microseismic event location with downhole DAS and geophones," details a source-imaging approach that eliminates the need for traditional manual event picking. This method is particularly effective for managing the high noise levels often encountered in Distributed Acoustic Sensing (DAS) data.
The research is co-authored by Eyal Shimony, Xiaoming Zhang, No'am Zach Dvory, and Ariel Lellouch. It highlights the collaborative efforts of our lab and international partners to advance the field of fiber-optic seismology. By integrating DAS and geophone data, the research provides a robust framework for clearer geomechanical interpretations, which is essential for the future of geothermal energy monitoring and subsurface characterization.
