Active seismic fault in New Zealand's South Island

The Greendale Fault is an active seismic fault situated in the Canterbury Plains in New Zealand's South Island. The fault was previously unknown to geologists until 4 September 2010, as physical traces of the fault had been buried by gravel (alluvial deposits) during the last glaciation period.[2]
