Fig. 5From: Ambient tectonic tremors in Manawatu, Cape Turnagain, Marlborough, and Puysegur, New ZealandTremor density and GPS displacement plots in: a Manawatu and b Marlborough. The tremor density (red bars) is based on a 30-day moving window. The GPS displacements consist of the detrended daily eastward displacements (black circles) at the GeoNet GPS stations in each region. Some of the known SSEs (2010–2011 and 2015–2016) appear to be related to an increase in tremor activityBack to article page
