A compiled and extensible database for building damage from the 2010-2011 earthquake sequence in Canterbury, New Zealand

Sheng-Lin Lin, S.R. Uma, Andrew B. King & Nick A. Horspool
The 2010–2011 Canterbury earthquake sequence in Christchurch, New Zealand caused widespread building damage. In response to each significant earthquake, local and central government and some private organisations conducted safety evaluation surveys. Furthermore, an extensive network of strong motion stations yielded a large ground motion data set. This report describes the tasks undertaken by the authors in association with their partners to (i) scrutinise and organise the massive amount of collected data; and (ii) derive a...

GeoNet New Zealand Seismograph Network

The GeoNet Project was established in 2001 to monitor New Zealand’s natural hazards and to provide freely available, high quality data to the research community. The GeoNet National Seismograph Network is one of GeoNet’s monitoring networks. It is made up of broadband and short-period instruments distributed around New Zealand, including offshore islands; Raoul Island and Chatham Islands. Broadband stations are evenly distributed throughout the country, and these are supplemented by more densely spaced instruments focussing...

Finding the concealed section of the Whakatane Fault in the Whakatane Township with a shear wave land streamer system

U Polom, C Mueller, A Nicol, P Villamor & RM Langridge
The principal objective of the presented study was to evaluate the usefulness of high-resolution shear wave seismic reflection profiling using a land streamer to locate buried faults in urban areas of New Zealand. A secondary objective was to locate the Whakatane Fault. In a calibration survey the method was first tested over a surface trace of the Edgecumbe Fault 30 km south-west of Whakatane township, that ruptured during the 1987 Mw 6.3 Edgecumbe Earthquake. This...

Hikurangi Ocean Bottom Investigation of Tremor and Slow Slip (HOBITSS III)

SA Henrys, R Harris, Y Ito, M Kido, C Kinoshita, T Muramoto, K Ohta, W Quinn, S Suzuki, F Tomita & H Zal
HOBITSSIII was a 12 day (19–30 June) Wellington to Wellington RV Tangaroa voyage (TAN1607) to recover previously deployed Absolute Pressure Gauges (APGs) along the northern Hikurangi margin. APGs measure vertical displacement of the seafloor. One APG from University of Texas Institute of Geophysics, UTIG and 5 APGs from Kyoto University were recovered. Five APGs from Kyoto University were also deployed on the TAN1607 voyage and will be recovered in mid-2017. Three separate 8–12 hour GPS-Acoustic...

Assessment of SeisComP3 automatic moment tensor solutions

Ristau
37 earthquakes with moment tensor solutions calculated using the SeisComP3 (SC3) automatic moment tensor module are compared with moment tensor solutions calculated manually using the method currently used by GeoNet. The earthquakes have a wide range of locations, moment magnitude (Mw 4.6 6.6) and depth (2 204 km). The similarity of the focal mechanisms are compared by calculating the principal axis angle ε0, which is the smallest angle needed to rotate one set of principal...
