Description:
Analysis of broadband teleseismic data shows that the 18 June 2000 Wharton Basin earthquake, a moment magnitude 7.8 intraplate event in the region of diffuse deformation separating the Indian and Australian plates, consisted of two subevents that simultaneously ruptured two near-conjugate planes. This mode of rupture accommodates shortening by a mechanism different from that previously known elsewhere in the region. The larger subevent occurred on a fossil fracture zone, with a relatively high stress drop of about 20 megapascals, showing that large stresses can accumulate in regions of distributed deformation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robinson, D P -- Henry, C -- Das, S -- Woodhouse, J H -- New York, N.Y. -- Science. 2001 May 11;292(5519):1145-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, University of Oxford, Parks Road, Oxford OX1 3PR, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11349145" target="_blank"〉PubMed〈/a〉
