SZ4D 2022 Community Meeting



We would like to announce a Community Meeting to discuss the ongoing planning efforts associated with the Subduction Zones in Four Dimensions (SZ4D) initiative. This meeting will provide the opportunity to discuss recent subduction zone science, update the community on the status of SZ4D, and solicit community feedback on next steps. In particular, we will be collecting input on near-future opportunities to seek funding for SZ4D needs. The meeting will be held at the Hyatt Regency Hotel in Houston, Texas from November 14-16, 2022. In addition, there will be an early-career event immediately preceding the meeting on November 13. More information regarding the Early Career Event will be available soon.


It is not necessary that you have worked on subduction zones before to obtain support, but it is desirable that you identify a connection to SZ4D for your future career.

We realize that travel to certain parts of the country raises concerns for some members of our community. Acknowledging these concerns, the location for the Community Meeting was chosen to balance a number of competing priorities, including travel accessibility for both US and Chilean scientists and the availability of an affordable venue large enough to host the community meeting this fall. We plan to engage members of the community who cannot travel to Houston by providing opportunities for virtual participation throughout the meeting. All participants, both virtual and in-person, will be expected to abide by the SZ4D Code of Conduct.


The deadline for this application is September 30th. Application remain open for virtual attendance


Decisions on participation and travel support along with a registration form in October. Late registration will be available as space permits. If additional funding is secured, we will notify additional participants as soon as possible.

We also encourage you to complete a second, optional survey with demographic information to assess the audience we are reaching for the SZ4D Community Meeting and for supporting diversity in meeting attendees. All responses are confidential, not tied to any identifiable information, and will only be discussed in assembled form (e.g. graphs, charts).

All participants are required to abide by the Code of Conduct


COVID Protocol

This protocol has been put in place to help protect all meeting participants and reduce the spread of illness, including COVID-19.


All in-person participants will be required to wear masks, unless they are giving a live presentation, or actively eating or drinking.

  • Extra masks, as well as hand sanitizer, will be available to participants during the workshop

To the extent possible, participant seating should be arranged with an eye toward maintaining social distancing.

  • A large venue has been selected for this meeting to allow for more space

  • Some events, like the lunches and breakout rooms, may still require participants to be seated in close proximity

  • Provided meals have been limited to only those that maximize meeting time, lunches on Day 1 and Day 2


On-site rapid test kits will be available at no cost for any participants who feel unwell, have COVID-like symptoms, were exposed to someone else who tested positive, or request a test for another reason.

  • Tests will be readily and freely available to encourage their use by anyone

Supported participants are allocated single-occupancy rooms, rather than double-occupancy rooms.

The meeting website will feature a dedicated COVID page that is prominently featured and regularly updated so participants can easily stay informed on the evolving safety practices and policies we have in place, allowing them to make an informed decision.

  • We will inform all attendees of known positive COVID cases at the meeting

  • We also want to ensure transparency so participants feel empowered to decide for themselves whether they feel comfortable attending in person.


A list of nearby testing locations will be provided to attendees who want a PCR test.

  • A list of nearby testing sites (and the ability to book appointments) is available here.

There is no registration fee to be refunded should travel plans change for participants based on COVID considerations. We want to encourage participants who test positive for COVID, or think they may be sick to stay home. Presentations will be available through a virtual Zoom meeting that is also free to all attendees.
