Description:
Unique attributes in sequences of recurring, similar microearthquakes at Parkfield, California, provide a means for inferring slip rate at depth throughout the active fault surface from the time intervals between sequence events. Application of the method using an 11-year microseismicity record revealed systematic spatial and temporal changes in the slip rate that were synchronous with earthquake activity and other independent measures of fault-zone slip. If this phenomenon is found to be generally common behavior in active faults, it forms the basis for a method to monitor the changing strain field throughout a seismogenic fault zone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nadeau -- McEvilly -- New York, N.Y. -- Science. 1999 Jul 30;285(5428):718-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Earth Sciences Division, Lawrence Berkeley National Laboratory, and Berkeley Seismological Laboratory, University of California, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10426990" target="_blank"〉PubMed〈/a〉
