- Summary
Pyrocko (https://pyrocko.org) is an open source seismology toolbox and library, written in the Python programming language. It can be utilized flexibly for a variety of geophysical tasks, like seismological data processing and analysis, modelling of InSAR, GNSS data and dynamic wave forms, or for seismic source characterization. The presentation introduces the framework and focuses on a flexible and computationally efficient f-k filtering technique for DAS data, which makes use of its dense spatial and temporal sampling, and can handle the large amount of data. The presented adaptive frequency-wavenumber filter suppresses the incoherent seismic noise while amplifying the coherent wave field.
Bio: Marius Paul Isken is a Geophysicist interested in observational seismology and earthquake source characterisation. He studied Geosciences (BSc) and Geophysics (MSc) at the University of Kiel and afterwards worked as a research seismologist at the USGS in Menlo Park and KAUST, Saudi Arabia. Before starting his PhD about distributed acoustic sensing (DAS) for earthquake modelling at the GFZ Potsdam with the section Physics of Earthquakes and Volcanoes in 2020, he worked as a software developer at the University of Kiel (2016 - 2020). In 2018 he co-founded QuakeSaver GmbH, pursuing the aim to develop smart seismometers and seismic networks.
