Does paleoseismology forecast the historic rates of large earthquakes on the San Andreas fault system?
Glenn Biasi, Katherine M. Scharer, Ray J. Weldon, Timothy E. Dawson
2016, Conference Paper, Proceedings of the 7th PATA Days, 2016
The 98-year open interval since the most recent ground-rupturing earthquake in the greater San Andreas boundary fault system would not be predicted by the quasi-periodic recurrence statistics from paleoseismic data. We examine whether the current hiatus could be explained by uncertainties in earthquake dating. Using seven independent paleoseismic records,...

Testing geomorphology-derived rupture histories against the paleoseismic record of the southern San Andreas fault
Katherine M. Scharer, Ray J. Weldon, Sean Bemis
2016, Conference Paper, Proceedings of the 7th PATA Days, 2016
Evidence for the 340-km-long Fort Tejon earthquake of 1857 is found at each of the high-resolution paleoseismic sites on the southern San Andreas Fault. Using trenching data from these sites, we find that the assemblage of dated paleoearthquakes recurs quasi-periodically (coefficient of variation, COV, of 0.6, Biasi, 2013) and requires...

2016, Proceedings of the National Academy of Sciences of the United States of America (113) E8089-E8095
Ecosystems can show sudden and persistent changes in state despite only incremental changes in drivers. Such critical transitions are difficult to predict, because the state of the system often shows little change before the transition. Early-warning indicators (EWIs) are hypothesized to signal the loss of system resilience and have been...
