This scientific workshop brings together more than 150 leading experts on Probabilistic Seismic Hazard Assessment (PSHA) from around the globe to discuss the current state of practice as well as future directions. The workshop will adopt a holistic point of view (i.e. interdisciplinary, multiple spatial- and temporal scales), critically reflecting all elements of modern PSHA.

Distinguished keynote speakers will introduce a range of topics, but we also call for solicited contributions (oral and poster). We will allocate sufficient time for discussions and networking, and the beautiful castle in Lenzburg offers a unique setting.

Revisiting past and ongoing site-specific projects on local, national or transnational scales, we strive to draw conclusions for future PSHA projects. We will also reflect on emerging challenges, such as time-dependence, earthquake interactions, anthropogenic seismicity, model validation, simulation based PSHA, communication of hazard results and procedural requirements for ensuring robustness, especially in the context of PSHA for critical facilities. On day three, we will focus specifically on the needs of community and harmonization projects, such as the next-generation European PSHA.


Lenzburg is a small town in Switzerland with nearly 10’000 inhabitants. It is located 20 minutes by train from Zurich main station and about 40 minutes from Zurich airport. At the foot of its medieval centre lies a rounded hill with the Lenzburg Castle on top at 504 meters above sea level.

Not only counts and dukes used to call Lenzburg Castle their home, also a German poet and an American adventurer once lived at this historically significant site. The castle has always been of great relevance to the region and lived through many political uprisings dated as far back as to the 12th century. In 1986, the castle was carefully renovated and finally opened to the public. Now, the Knight’s Hall, an impressive courtyard and enticing gardens are awaiting us for the first PSHA Workshop.
