Objectives
To develop a global knowledge base of technical capabilities and opportunities in seafloor geodesy and seismology.
GOALS: The SZNet Ocean Floor Observational Technology Workshop aims to address the issue of ocean floor instrumentation which is a key component of multiple of our participating networks’ efforts around the world. The purpose is to develop a global knowledge base of technical capabilities and opportunities in seafloor geodesy and seismology based on the need identified in the SZ4D Implementation report.
Exchange state-of-the-art technical information as well as current observational capabilities.
Highlight needed instrumental advances and knowledge gaps.
Promote collaborations and cooperative experiments.
Generate a workshop report: The organizing committee will produce a 2-3 page document listing primary outcomes of the workshop conversations, specifically highlighting needs of the community to help target the focus of future efforts.
STRUCTURE: This workshop will be scheduled over the course of two days in conjunction with other events that week organized by the science of slow to fast earthquakes network. This format is intended to leverage the resources of both organizations to increase attendance and reach.
The schedule of events is as follows:
January 11-12: Pre-workshop field trip (organized by Slow to Fast EQ)
January 13-14: Slow-to-Fast Earthquake Workshop
January 15-16: SZNet Ocean Floor Observational Technology Workshop

January 11-12: Pre-workshop field trip
This field trip is being organized by the Slow to Fast Earthquak Network. With any questions please visit the SFEQ website or contact them at sfeq-oshikake-group@g.ecc.u-tokyo.ac.jp. Below is some premilinary information.
This trip involves a two day-long excursions to several field sites near Santiago, Chile.
Please note that due to bus capacity, participation on this trip is limited to 40 participants on a first come, first served basis.
Dates: January 11-12, 2025
Transportation: Bus transportation too and from field sites is provided. Meeting times and locations will be provided, along with a detailed schedule prior to the event.
Food: Food is not provided by trip organizers. Participants are expected to bring a packed lunch on both days of the trip.
Lodging: Lodging is not provided by event organizers. Participants are expected to book their own lodging in Santiago, Chile
Financial Assistance: No financial assistance is available for this event.
Tentative Schedule:
Day 1: Visit to the western piedmont of the Andes mountain front, focusing on the fault trace of the active San Ramón Fault (last major earthquake c.a. 8 ka).
Day 2: Explore a transect through the Cajón del Maipo valley, penetrating into the Andes, from the San Ramón Fault, in the west, to the vicinity of the San José volcano (last eruption in 1960), in the east. Several stops will be made along the way to observe geological units, structures, and geomorphic features to understand the evolution of the Andes.
January 13-14: Slow-to-Fast Earthquake Workshop
Dates: January 13-14, 2025
Location:
Beauchef 851, Santiago, Chile
Faculty of Physical and Mathematical Sciences of the Universidad de Chile.
Workshop Description: 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 earthquakes in Chile and Japan, where seismic activity is always high and earthquake disasters are a common social problem. This workshop will foster discussions into the latest insights on earthquake phenomena including slow earthquakes, therefore inviting future collaborative research.
For more information, please visit the SFEQ website or contact them at sfeq-oshikake@g.ecc.u-tokyo.ac.jp
