Meeting Abstracts

SCEC Annual Meeting participants are invited to share recent results and activities relevant to SCEC priorities and initiatives during the poster sessions. The SCEC collaboration emphasizes the connections between information gathering by sensor networks, fieldwork, and laboratory experiments; knowledge formulation through physics-based, system-level modeling; improved understanding of seismic hazard; and actions to reduce earthquake risk and promote resilience.

A SCEC username is required to submit an abstract.

The person submitting the abstract is automatically the First Author, and will receive all communications regarding the abstract.

A First Author can have a maximum of one poster and one oral presentation (if invited as a plenary speaker).

Each "poster space" in the online gallery will include general poster information, author contact information, and a PDF of the poster, as well as optional short videos about the poster.

First Authors of accepted abstracts will receive more detailed instructions.

During the meeting, posters are presented in three groups: A (Monday September 12), B (Tuesday September 13), and C (Online Only). See the SCEC2022 agenda and FAQ for more details.
