ABOUT EUROCONF23 After 20 years the 15th Euroconference on Rock Physics and Rock Mechanics (EUROCONF23) will be held in the Netherlands again! Following the tradition from many previous, highly successful, Euroconferences we found a somewhat secluded location in a nice natural setting, to allow for maximum interaction and mingling between participants.  For this edition, we would like to take you to Woudschoten, a beautiful location in the woods in the centre of the Netherlands. We hope to see you in the flatlands from Monday 23 October to Thursday 26 October.
