TUESDAY, APRIL 17 @11A PT *** NEW DATE TIME • New developments in AxiSEM/Instaseis for seismic wave propagation on local scales • Lion Krischer, Simon Staehler, and Martin van Driel, ETH Zurich; Tarje Nissen-Meyer, Oxford University • Instaseis (http://instaseis.net) is a Python tool to quickly extract high-frequency seismograms for any source-receiver geometry from databases generated with AxiSEM (http://axisem.info/). 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 (http://ds.iris.edu/ds/products/syngine/). 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.
