Seismic Array HiKurangi Experiment (SAHKE) data
This is the data collected by a major controlled-source and passive seismic imaging experiment, the Seismic Array HiKurangi Experiment (SAHKE). The SAHKE project was designed to investigate the physical parameters controlling locking at the plate boundary beneath the southern North Island and characterise slip processes in a major segment of the Hikurangi system. The components of data were acquired between November 2009 and April 2010 by GNS Science, Victoria University of Wellington, and Earthquake Research Institute (University of Tokyo, Japan) in conjunction with Ministry of Economic Development, Crown Minerals. 480 km of marine multichannel seismic data were acquired on 3 SAHKE profiles off the east and west coasts of the southern North Island and recorded by 36 short-period, 10 broadband and 20 ocean bottom seismometers along a single transect line. Additional offshore shot lines were recorded by 9 short-period seismometers in a north-south profile line, on the western margin, and 13 short-period seismometers on two profile lines on the eastern margin of the lower North Island. Additionally, 69000 offshore airgun sources were recorded by 48 short-period and two broadband seismometers distributed in a dispersed array during the recording of 2800 km of the Pegasus Basin survey. This same distributed array recorded local and teleseismic earthquakes over a 4 month period.
