Seismology everywhere
Current collaborations
standing next to giants (without stepping on their toes)
Philippe Lognonné
Université de Paris / IPGP
The original planetary seismologist. Philippe was behind the decade-long effort to get a seismometer to Mars. We collaborate on InSight and after InSight towards the moon.
Mark Panning
Jet Propulsion Laboratory
Mark is at the place that gets stuff to space and to planets. He makes sure that seismometers are on board.
Domenico Giardini
ETH Zürich
The head of our group at ETH. Together, we aim at investigating what InSight's seismic data tells us about Mars.
Kasra Hosseini
University of Oxford / Alan Turing Institute
Kasra will be the first to use M.C. Kernel for a seismic tomography, based on his extensive P and Pdiff dataset
Anna Mittelholz
Harvard University
Despite not being a seismologist, Anna is curious about marsquakes and what they tell us about the planet's geological history.
Céline Hadziioannou
University of Hamburg
Earthquake-free seismology. Using seismic signals created from ocean waves, trucks or just anything for monitoring.

Seismic wave propagation in icy ocean worlds
The next years will see the decision for a seismometer-equipped lander on Europa or Titan. We tried to predict what could be measured on Europa, Titan, Enceladus or Ganymede.

Fully probabilistic seismic source inversion – Part 2: Modelling errors and station covariances
The long-awaited sequel
How can we construct a Likelihood function for non-Gaussian noise on seismic waveforms? Turns out that the dependable Correlation Coefficient follows a log-normal distribution, so we can use that.

Fully probabilistic seismic source inversion I - Efficient parametrization
This paper deals with the inverse problem of seismic point source inversion. It describes an efficient parametrization to invert for earthquake depth, moment tensor and source time function using Bayesian inference with Malcolm Sambridge's Neighbourhood Algorithm.

Instaseis: instant global seismograms based on a broadband waveform database
Instaseis is a Python library to calculate broadband seismograms for arbitrary source-receiver configurations, including finite faults and single forces from a stored AxiSEM wavefield.

Monitoring stress changes in a concrete bridge with coda wave interferometry
Coda waves contain information about a large volume around the source and receiver. We use that method to monitor stress changes in a bridge during construction.
