After a relatively quiet period, Christchurch and Canterbury have experienced several fair-sized aftershocks in the last few days. According to Geonet, the shakes were of the following magnitudes:
Tuesday May 15th, 1:27pm, 4.5 earthquake, 11 kilometres deep, 10 kilometres north-east of Chirstchurch
Sunday May 20th, 9:35am, 4.1 earthquake, 10 kilometres deep, 20 kilometres west of Christchurch
Sunday May 20th, 5:06pm, 4.8 earthquake, 8 kilometres deep, 20 kilometres east of Christchurch
After the Sunday shakes, Facebook was flooded with comments from locals about how the quakes had felt and concerns that two large shakes in one day may be a sign of more movement to come overnight.
