12/5/2023 – EnVision meeting

We presented two talks on Venus seismology at the EnVision meeting in Berlin, Germany. It was a great meeting overall. Who knew so many people are doing exciting Venus science?!

16/3/2023 – Meeting up at LPSC

Quite a few of us attended the Lunar and Planetary Science Conference (LPSC) in the USA and so we met up for a drink to discuss all things Venus seismology!

30/1/2023 – First ISSI team meeting in Bern!

We had our first in-person ISSI team meeting last week! Almost the entire team was able to make it (with some remote participation), and most of the team was able to come to Bern, Switzerland in person. Apart from seeing each other in 3D for the first time, we finally crunched some numbers and were able to make preliminary estimates of the expected seismicity on Venus. In particular, we quantified the frequency of quakes with a magnitude of 6 or higher, which are within the (pessimistic) detection limits of existing detection methods. We also quantified the minimum amount of quakes of different magnitudes that can be detected with the current methods.

We further benefited from many interdisciplinary discussions and made progress on the estimation of the seismogenic zone depth and volume of Venus from different types of models and elastic thickness estimates. We also looked into the expected seismic noise on Venus to determine what amplitude signals we could still reasonably detect.

Practically speaking, we drafted an outline for a team paper and distributed tasks among the team members, with many paragraphs already written by this highly dedicated team. We also made significant progress on papers where subgroups of the team are involved. In general, this meeting was a great opportunity for all our team members to learn more about Venus, seismicity, and of course seismicity on Venus. We are excited to continue and refine our work on Venus seismicity now that a strong foundation for our various collaborations has been built!

09/8/2022 – ISSI team kick-off meeting

We had our first (zoom) team meeting on August 9, 2022, so the ISSI team has now officially started! We played bingo and found out which team members have a twin and multiple nationalities, own a telescope, or dislike cheese fondue (important information for when we go to Bern, Switzerland for our in-person meeting). Richard Ghail also gave an overview of all the mysteries Venus still holds to set us off on our Venusian seismology journey.

18/7/2022 – Save the date!

The first in-person ISSI team meeting will take place in Bern, Switzerland from January 23 – 27, 2023. During this meeting, we will review, discuss, and mainly actively work on projects to estimate the current level of seismicity on Venus. We also selected a day & time for the virtual monthly meetings: Tuesdays at 17:00h. The schedule of the monthly meetings with the exact dates can be found here.

24/5/2022 – ISSI Team funded!

Our ISSI Team “Seismicity on Venus: Prediction & Detection” led by Iris van Zelst was selected for funding by ISSI. The team consists of international experts on (planetary) seismology, geodynamics, and geology, including Andreas Fichtner, Raphaël F. Garcia, Richard Ghail, Anna Horleston, Taichi Kawamura, Philippe Lognonné, Julia Maia, Csilla Orgel, Mark Panning, Ana-Catalina Plesa, and Leah Sabbeth. The team will soon start working on investigating the seismicity of Venus through modelling and observations from its geological record, and propose hypotheses for testing their predictions by future missions. Stay tuned for exciting results to come!
