Description:
Deep fault slip information from characteristically repeating microearthquakes reveals previously unrecognized patterns of extensive, large-amplitude, long-duration, quasiperiodic repetition of aseismic events along much of a 175-kilometer segment of the central San Andreas fault. Pulsing occurs both in conjunction with and independent of transient slip from larger earthquakes. It extends to depths of approximately 10 to 11 kilometers but may be deeper, and it may be related to similar phenomena occurring in subduction zones. Over much of the study area, pulse onset periods also show a higher probability of larger earthquakes, which may provide useful information for earthquake forecasting.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nadeau, Robert M -- McEvilly, Thomas V -- New York, N.Y. -- Science. 2004 Jan 9;303(5655):220-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Berkeley Seismological Laboratory, 211 McCone Hall, University of California, Berkeley, CA 94720-4760, USA. nadeau@seismo.berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14716011" target="_blank"〉PubMed〈/a〉
