Tetsuo Takanami, a Carnegie Fellow at DTM during 1991 – 1993, returned as a Visiting Investigator for a 12-month period, ending on 31 April 2010. While at DTM, Dr. Takanami will be processing and analyzing borehole strainmeter observations from Hokkaido, including those from the M8 2003 Tokachi-Oki earthquake, possible slow-slip events along the Japan and Kurile trenches, and other measurements pertinent to the heterogeneity of intraplate coupling along those two subduction zones. Dr. Takanami, who will be collaborating with DTM’s Selwyn Sacks and Alan Linde, recently retired from his faculty position as an Associate Professor at the Institute of Seismology and Volcanology at Hokkaido University.
