On 14 August 2024, Franco Siccardi died at the age of 82. Along with a few others, I was asked to write a few lines in his memory.
Ages, histories, fortunes, interests and ideas separated us, but I have admired and esteemed Franco since I met him almost 40 years ago. From him I received appreciation, respect and help. Admiration and esteem for Franco have been natural, inevitable, firm for me. His appreciation, on the other hand, has always seemed unmotivated, inexplicable, unexpected, and for that invaluable. Thank you Franco.
After 14,547 days of work, 13,360 days for the Italian National Research Council (CNR) and 1,187 days for the National Department of Civil Protection, I have (finally!) retired.
On 1 July, I gave a lecture to some 25 students from around the world at the IAEG Summer School on Natural hazards, societal impact and risk. From theory to practice: identification, assessment, and remediation. The school was held in the Aosta Valley, and the beautiful scenery helped a lot.
On March 22, 2024, for the United Nations' XXIII World Water Day, the Accademia Nazionale dei Lincei hosts a conference on Adaptation to extreme events in the hydrological cycle: floods and droughts. Despite the title, I was invited to give a talk on Landslides and landslide risk in Italy (in Italian, sorry!). A recording of the conference is available on the Lincei channels.
At the February 8, 2024 monthly gathering of the Accademia dei Lincei I gave a talk (in Italian, sorry!) on landslide characteristics and current prediction capabilities. The presentation is available here and a recording of the talk and the discussion here.
At the 2023 conference of the CNR Department of Earth System Sciences and Technologies for the Environment, I gave a talk (in Italian, sorry!) on geo-hydrological hazards in a warming climate, with insights on how to organise future research on related hazards and risks. A recording of the talk is available here.

I have become a corresponding member of the Lincean Academy, one of Europe's oldest and most prestigious scientific institutions, founded in 1603.
I am truly honoured by this unique privilege.
Representing Italy in the Council of the IUGG, the International Union of Geodesy and Geophysics
A review talk on landslide early warning systems given on 27 June, 2023, at the 8th International Conference on Debris Flow Hazard Mitigation (DFHM 8) in the beautiful (and hot!) Torino, Italy. A very interesting conference.

An article by Sara Moraca on the Italian National Plan for Adaptation to Climate Change for Nature Italy, to which I contributed with a short interview on geo-hydrological hazards.
After three years and three months, I left my job at the National Department of Civil Protection and returned to the National Research Council (Cnr) in Perugia.
Together with Stefano L. Gariano and Paola Salvati. After too many months of forced apnea, a (too short) breath of fresh air.
A story by Kendra Pierre-Louis on climate and landslides in the science section of The Atlantic, to which I have contributed with an interview.
All you need to know about rainfall and its consequences. A new book edited by Renato Morbidelli, with a chapter on rainfall and landslide initiation.
I gave a presentation on the role of science for civil protection at the meeting Science for Civil Protection Day, part of the 2021 National civil protection week.
I had the chance to brief Prime Minister Draghi on the forecast and prevention activities conducted by the Civil Protection Department.

In a new "perspective" article in NHESS, I outline my views on the predictability of landslide populations caused by different triggers, and I provide recommendations on what to do to improve our ability to predict landslide populations. The article appeared in a special issue of NHESS to celebrate the journal's 20th anniversary. Happy birthday HNESS!
The news of the Soloviev Medal came with an email, as unexpected as it was welcome. I have spent a good part of my research career dealing with natural hazards, particularly geo-hydrological hazards, and I am happy that the EGU has recognised my work, which is also that of the many colleagues I have worked with. You can read the motivation for the award here, and an interview for the EGU Natural hazards blog here.

Antonello Pasini, climatologist, Cnr scientist and blogger, asked Alessio Valente and myself to contribute in one of the chapters of his new book "L'equazione dei disastri" (The disaster equation). It was fun and instructive to work with Antonello and Alessio on chapter 3 of the book, devoted to the anthropization and fragility of the Italian territory, and on the expected consequences of the changing climate.

These are some of the questions that 80 Italian scientists interested in the prediction of natural hazards have discussed in a two day workshop held by the Italian IUGG committee at the Cnr headquarters in Rome, Italy, on 26 al 27 November 2019. Sixteen keynote speakers set the ground for a series of engaging and fruitful discussions. An experience to repeat, hopefully soon ...
Students and teachers of the Istituto Tecnico Tecnologico Statale "Alessandro Volta" and researchers of the CNR Research Institute for Hydrogeological Protection in Perugia presented a joint activity to increase the awareness of natural hazards and their consequences.
I had the privilege to be invited and to give a keynote at the 12th Asian Regional Conference (ARC) of the International Association of Engineering Geology and the Environment (IAEG), held in the wonderful island of Jeju, South Korea, from 23 to 27 September 2019. Nice people, great setting and spectacular volcano geology and geomorphology.
John Ioannidis and his colleagues have published an interesting paper in PLOS Biology to present their standardized citation metrics author database annotated for scientific field. The database contains data used to rank 100,000 "top" scientists - whatever that means - globally, in all fields of science.
Have fun snooping through the lists!
I was fortunate to attend the Centennial International Cooperation in Earth and Space Sciences workshop, held at the UNESCO Headquarters, in Paris, France, on 29 July 2019. Some of the talks given at the workshop were truly inspiring.
I participated to the first event of the School for Science in Diplomacy, school4SID, organized by CNR and the Istituto Tecnico Nautico Caboto, in Gaeta, Italy, from 5 to 7 June 2019. Great idea, great people, great setting and ... amazing food.
