While we were at sea aboard the R\/V Tangaroa, this M 7.8 and associated complicated earthquakes occurred. We initiated planning to modify our goals to include data collection in response to this earthquake series. This included (1) additional sediment coring and (2) seismic reflection and multibeam bathymetric mapping. The coring is important because this earthquake is a small earthquake for turbidite paleoseismology, so the results will be an important contribution to the global studies of trigger magnitude-distance relations. The seismic reflection data are important to determine the extent of surface rupture of the faults offshore. The multibeam mapping also helps extend our observations of surface rupture offshore. These observations will help constrain fault slip models. Some of the results from our cruise are presented below. We prepared this presentation for a press conference immediately following our cruise.<\/p>\n
We are currently preparing samples to submit to a lab in New Zealand to test for the presence of short lived radionuclides (7Be and 234Th). We are also conducting biostratigraphic tests on the most recent sedimentary deposit. These tests are an important tool to justify our interpretations that we cored the M 7.8 turbidite using lithostratigraphic constraints.<\/p>\n
