Comparing 2011 and 2016 New Zealand earthquakes
Monday's quake struck New Zealand's South Island in a mostly rural area that's dotted with small towns.
Both quakes were followed by a large series of aftershocks, many of them strong.
Since Monday's quake, at least four temblors of magnitude 6.1 or higher have been recorded in the region.
[...] the death toll from Monday's quake stands at two, with one person dying in the small coastal town of Kaikoura and another in Mt.
Prime Minister John Key said authorities had no reason to believe the death toll would climb further.
