We have been very lucky and honoured to host the 15th LARAM school 1st @ UNIL, from 2 to 13 September 2019 on the request of the team of the University of Salerno. We organized this summer school with our PhD students, which brought together around thirty PhD students and post-docs from all over the world. Nearly 30 teachers among the best experts on the landslide risks have taught during these 15 days. It was a great success. 4 PhD of UNIL participated.
