UTIG RESEARCH PROJECTS ARCHIVE
Paleoseismic Investigation FLYER
Collaborative research UTIG and USGS/Menlo Park:
Towards an integrated
understanding of Late Holocene fault activity in western Puerto Rico: Onland
scarp mapping and fault trenching
Principal Investigators:
Paul Mann
Carol Prentice (USGS)
Funded by: USGS - National Earthquake Hazard Reduction Program
This study will focus on the mapping of fault scarps and will attempt to
locate sites suitable for trenching in the second year of the study. A
companion, USGS-funded offshore study by Grindlay et al. is described in a
second web page.
