SUMMARY:Quantifying complexity in challenging data: fault slip rates on mi
 llennial timescales - Laura Gregory\, University of Leeds
DTSTART:20221101T120000Z

DESCRIPTION:We are frequently surprised by earthquakes that occur in unexp
 ected places and at un-‘predicted’ times. Some faults seem to have fai
 rly regular earthquakes\, particularly at plate boundaries\, but many do n
 ot. In this seminar\, we will explore how and why earthquakes reoccur in t
 ime and space. I will present how landscape processes interact with tecton
 ics\, and how this impacts on the expression of active faulting preserved 
 on Quaternary timescales. We will then delve into the methods that can be 
 applied to quantify fault slip on millennial timescales\, using cosmogenic
  data from normal faults in western Turkey and Central Italy. These data a
 re rarely straightforward\, but we will begin to understand how complex fa
 ulting (or not) can be inferred\, and how data from the past can inform ou
 r understanding of the pattern of faulting and the likelihood of future de
 vastating events.
