1 PROBABILISTIC SURFACE FAULT DISPLACEMENT HAZARD ANALYSIS (PFDHA) DATA FOR STRIKE SLIP FAULTS PEER SURFACE FAULT DISPLACEMENT HAZARD WORKSHOP U.C. Berkeley May 20-21, 2009 Timothy Dawson California Geological Survey 1
2 Background PEER Lifelines sponsored project to develop improved design-oriented conditional probability models needed for estimating fault rupture hazard within either a deterministic or probabilistic framework, and implementing them both in spreadsheet form and as trial fault rupture hazard maps. 2
3 Problem to solve: What is the probability of displacement at the site if the rupture occurs on a mapped fault? Earthquake rupture Distance (m) Site FAULT 3
4 This Study Adapted approach described by Coppersmith and Youngs (1999) and Youngs and others (2003) for normal faults and modified it for strike-slip faults. 4
5 Principal vs Distributed Faulting Coppersmith and Youngs (1999): Principal faulting is slip along the main plane (or planes) of crustal weakness responsible for the release of seismic energy during the earthquake Distributed faulting is defined as displacement that occurs on other faults, shears, or fractures in the vicinity of the principal rupture in response to the principal faulting (triggered slip near and far-field) 5
6 Data Needs Principal Faulting Distribution of earthquakes (location & magnitude) - Location and magnitude from ground motion hazard studies (NSHM) - Probability that faulting reaches the surface (Wells and Coppersmith, 1994) 6
7 Data Needs Principal Faulting Distribution of displacement along fault trace (slip distributions) -This study (Used in Petersen and others, 2004; in prep - More comprehensive analysis by Wesnousky (2008) Hector Mine EQ (Treiman et al. 2002) 7
8 Data Needs Distributed Faulting Distribution of secondary faulting Magnitude of displacement on secondary faults Coppersmith and Youngs,
9 Data Needs Uncertainty in location of mapped fault traces 9
10 Earthquakes in Analysis Selected based on high-quality, large scale (>1:50,000) mapping 1968 Borrego Mountain 1979 Imperial Valley 1987 Superstition Hill/Elmore Ranch 1995 Kobe (Japan) 1999 Izmit and Duzce (Turkey) 1999 Hector Mine 10
11 Examples of strike-slip earthquakes in analysis Scale varies 11
12 Principal faulting displacement 12
13 Distribution of Secondary Faulting Examined in GIS for various footprint sizes 100x100 m cell 25x25 m cell 13
14 Secondary Faulting Displacements 14
15 Uncertainty in location of mapped fault traces This study: Examined deviation of mapped fault trace from rupture trace Used Alquist-Priolo (mostly) maps and compared them against earthquake rupture maps in same areas (e.g. Landers, Hector Mine) Categorized by location uncertainty of mapped trace 15
16 Uncertainty in location of mapped fault traces Comparison of surface fault rupture in Landers earthquake, 1992 with preearthquake fault mapping from Alquist-Priolo Earthquake Fault Zones Map 16
17 Approach ALQUIST-PRIOLO EARTHQUAKE FAULT ZONES MAPS ARE A TYPICAL SOURCE FOR PRE-EARTHQUAKE FAULT MAPPING FAULT TRACE CATEGORIES ACCURATELY LOCATED APPROXIMATELY LOCATED INFERRED CONCEALED 17
18 Examples Comparison of surface fault rupture in Landers earthquake, 1992 with pre-earthquake fault mapping from Alquist-Priolo Earthquake Fault Zones Map 18
19 INPUT FOR PDF Distance along fault Category Distance from mapped trace DATA EXTRACTED FROM GIS inferred inferred approximate approximate well-located well-located well-located approximate approximate inferred inferred PROBABILITY DISTANCE FROM FAULT ADDITIONAL ANALYSIS Test whether or not other variables influence mapping accuracy 19
20 FAULT COMPLEXITY 1. Bends 2. Branches 3. Stepovers 20
21 All (mean) SD Accurate (mean) SD Approximate (mean) SD Concealed (mean) SD Inferred (mean) Undifferentiated Simple Complex SD 21
22 What are the variables that control rupture trace location? Uncertainty due to mapping accuracy, map scale, quality of mapping (Epistemic): Can be addressed with more detailed studies Uncertainty due to variability of rupture location from earthquake to earthquake (Aleatory).: Not yet addressed. What is the variability in rupture location from earthquake to earthquake? 22
23 To be continued... (see Mark s talk tomorrow) 23
