ENS project (2017 - )

I have been officially an associate researcher at Laboratoire de Geologie de l'ENS Paris since January 2017 (about 20% = once a week).
It is very welcome to discuss any topics in Paris. A prior appointment recommended.

Current topics

• Multi-scale heterogeneous fault model for earthquake dynamics since Ide and Aochi (2005).
• Kinematic and dynamic modeling of the 2015 Mw8.3 Illapel (central Chile) earthquake.
• Modeling of the 2019 Mw7.1 Ridgecrest (California) earthquake. (not sure yet)

Expected topics

• Near-field Ground Motion and earthquake source dynmaics.
  It lacks observations for large earthquakes (M > 6) at near field (distnace < 10 km). How are they? All the earthquakes cited have particularity in detail such as segmentation, geometry change, super-shear rupture and so on. These are the subjects of research.

Archieved topics (or almost)

• 2016 Central Italy earthquake sequence.

Collaborations

are very welcome and totaly open officially or personally.

• within ENS and IPGP.
• Kobe University, Japan.
• University of Tokyo, Japan.
• Universidad de Chile, Chile.
• some other preliminary possibilities.
