2017-18 Webinar - AxiSEM/Instaseis

Apr 17th 11:00 am - 12:00 pm

New developments in AxiSEM/Instaseis for seismic wave propagation on local scales"

Lion Krischer, Tarje Nissen-Meyer, Simon Staehler, and Martin van Driel, ETH Zurich

Instaseis ( is a Python tool to quickly extract high-frequency seismograms for any source-receiver geometry from databases generated with AxiSEM ( So far it has been limited to global datasets, which in turn limited the maximum frequencies due to exploding storage requirements; a number of global databases are hosted by the IRIS DMC ( We recently expanded the AxiSEM/Instaseis combination to additionally handle local scale  simulations as well as databases, which enables much higher frequencies. 

In this webinar, we present a short overview of the theory behind AxiSEM/Instaseis, highlight the new extensions for local scale simulations and databases, and show a short practical tutorial on how to use it.
