A joint SCEC-IRIS-UNAVCO collaboration responded to NSF’s Mid-scale Research Infrastructure-2 solicitation by proposing a systematic deployment of linear instrumental arrays that cross the three major branches of the San Andreas system in southern California. The proposed Rupture and Fault Zone Observatory (RuFZO) is focused on in-situ observations in the immediate vicinity of fault zones where rocks suffer permanent deformation during faulting events. Near-fault arrays collecting continuous seismic and geodetic measurements and dense temporary nodal surveys will complement, and be integrated with, the data recorded by the regional networks.
How can the RuFZO facility best serve the earthquake science community? Your answers to this questionnaire will help us (and you) to prepare for the group discussions at the online RuFZO workshop on April 13, 2021. To participate in the workshop, register at:
https://www.scec.org/workshops/2021/rufzo.
At this first workshop, we will give an overview of the RuFZO concept. Then we want to hear from you about key features of pre-, during, and post-rupture processes and other signals that should be targets for observations by the RuFZO. A follow-on workshop on shaping the facility design will be held later this summer. Throughout spring and summer 2021, everyone is invited to share their ideas and provide additional input on developing RuFZO via this online questionnaire and/or by contributing a short video or extended abstract. We will make available videos and abstracts for which authors have granted permission to share publicly. The community’s input will inform the development of the full RuFZO proposal.
It would be most helpful to receive your initial input by April 9, 2021. You are welcome to provide additional feedback beyond that date.
