(Reports updated) Slow-to-Fast Earthquake Workshop in Chile was held
Slow-to-Fast Earthquake Workshop in Chile was held in cooperation with SZNet.
In recent years, our understanding of earthquakes has significantly changed. Not only have conventional earthquakes been studied, but various slow earthquakes have also been discovered, necessitating a reconstruction of earthquake science based on the comprehensive understanding on slow-to-fast earthquakes. Moreover, the importance of interdisciplinary research crossing over into the fields of geophysics, geology, and physics, as well as the adoption of new research methodologies in engineering and computer science, has become increasingly critical.
To deeply understand these phenomena, it is also effective to explore the controlling factors given their diversity. Notably, the seismogenesis in different subduction zones exhibits both similarities and differences. In particular, there is much to learn from comparative studies of Japan and Chile, where seismic activity is always high and earthquake disasters are a common social problem. Therefore, we host a workshop to discuss the latest insights on earthquake phenomena including slow earthquakes, and to foster future collaborative research, mainly in these regions and also including global subduction zones.

Workshop
On January 13 and 14, 2025, we held the “Slow-to-Fast Earthquake Workshop in Chile” at the Universidad de Chile in Santiago, Chile. The workshop was held in cooperation with the “Ocean Floor Observation Technology Workshop” (January 15 and 16) organized by SZnet, the subgroup in charge of international joint research of the U.S. program SZ4D.
The workshop featured research related to slow-to-fast earthquakes in Chile, as well as case studies from offshore Alaska, Canada, the U.S., Mexico, and Peru. More than 100 people attended the workshop, including 21 participants from Japan. 45 oral presentations and 9 posters were presented and discussed intensively.
The “Ocean Floor Observation Technology Workshop,” which followed the workshop, introduced Japan’s proud seafloor observation technology and cutting-edge research results, attracting a great deal of attention from overseas researchers. In particular, the Breakout Session held during the workshop was very impressive, with many Japanese participants actively participating in the session.
About field trips
Before the workshop, field trips were conducted on January 11 and 12.
On January 11, we observed a trenching survey of the San Ramon Fault in the suburbs of Santiago City. It was impressive to see Chilean researchers working on the survey using “Nejiri-gama (Japanese special sickle).” You may consider purchasing a “Nejiri-gama” as a souvenir when you visit Chile in the future!
On January 12, we visited the river terraces along the Maipo River and saw the volcano San Jose from El Cabreiro, which is located upstream of the terraces. Unfortunately, the summit area was covered by clouds, but we enjoyed a 30-minute trek under blue skies while viewing the glacial terrain.
Conclusion
Through this workshop and field trip, the exchange between researchers and students from Japan and other countries was further deepened. Let’s continue to strengthen international collaboration and develop research on Slow-to-Fast Earthquakes! Thank you very much for your participation!
