Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

Unlike proposal or journal reviews, in-field reviews cannot be anonymous. Paleoseismology presents a special case in which it is crucial to have colleagues review interpretations and give critical scientific input while the trenches are still open. While past practice has led to a highly evolved and sophisticated 'state-of-the-art' within the investigator community, it is not always possible from the logistical standpoint to have key people participate in field reviews. Day 3 will focus on how we, as a community, define the current state-of-the-art as a goal for best practice. We will attempt to formalize objectives for the future. For example, how best might one conduct multiple independent investigations and interpretations of a single paleoseismic site by parallel investigator teams? Given the budget constraints, how might this team approach be made more efficient while ensuring robust results through some measure of redundancy?
