In Lehmann’s Terms – the Story of the Singular Seismic-Wave Spotter
It’s International Women’s Day 2023, so the EGU Seismology Division would like to celebrate the life and work of singular seismic-wave spotter – Inge Lehmann (1888-1993), a Danish seismologist who discovered that the inner core was solid! Inge Lehmann grew up in a family of high aspirations, with several family members being politicians, scientists, and …[Read More]

Earthquake Watch: The Guanshan, Chih-shang sequence in Taiwan, 17-18 Sept, 2022
Contribution about the September 2022 M 6.6 and M 6.8 earthquakes in South-East Taiwan Dr.Yifan Yin , recent graduate at the Swiss Seismological Service (SED) at the Earth Sciences department of ETH Zürich. On 17 September 2022, a magnitude 6.6 quake shook the southern-east Taiwan. The merely 8.6 km deep quake was widely felt across …[Read More]
On the Frontline of the Mission for Marsquakes
This week we interview Géraldine Zenhäusern, a PhD student at ETH Zurich’s Department of Earth Sciences, about her experience of being on the frontline of spotting Marsquakes with NASA’s InSight mission…. What is the InSight mission? The NASA InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) mission is a geophysical observatory (see Fig. …[Read More]
Marsquake Detection with Machine Learning Methods
We interview Nikolaj Dahmen, a PhD student at ETH Zurich’s Institute of Geophysics, about how he uses Machine Learning methods to detect Marsquakes using data from NASA’s InSight Mission…. Why are marsquakes important to detect? Marsquakes generate seismic waves that travel from its source through the interior of the planet. The recordings of these waves …[Read More]
Opinion: self-supervised Machine Learning in seismology
Martijn van den Ende, a Postdoctoral research fellow at Université Côte d’Azur, writes about his thoughts on the state of Machine Learning in seismology… At this moment of writing, it is unlikely that any experienced seismologist is unaware of the recent advancements of Machine Learning (ML) methods in Earth Sciences. Some pioneering studies started paving …[Read More]
