Ground deformation occurring in the Greater Vancouver region, British Columbia, from twenty years of ERS-ENVISAT-RADARSAT-2 InSAR observations / [by] S.V. Samsonov ... [et al.]. : M103-2/2015-5E-PDF
Ground subsidence in the south-western part of British Columbia was measured from radar imagery using an advanced processing methodology developed by authors. During the period July 1995 - October 2012, we observed fast ground subsidence with a maximum rate greater than 2 cm/year in the Greater Vancouver region that includes the Fraser River delta and the cities of Burnaby, Richmond, Surrey, and Vancouver. The fastest subsidence was observed beneath the Vancouver International Airport and around agricultural and industrial regions. Rapid sub-centimeter ground deformation also occurred during the summer and fall of 2009-2012. These time series suggest that the subsidence rate at the studied regions does not decrease with time as suggested in previous studies but actually increases. The long term impact of subsidence on infrastructure can be significant and needs to be investigated further.
