Recent Seismic Activity
The most recent earthquake on the Hope Fault was the 1888 North Canterbury earthquake, which ruptured the whole of the Hope River segment. Alexander McKay, a geologist working for the New Zealand geological survey, observed horizontal offsets in farm fences of between 1.5 and 2.6 metres along the fault. He was the first to associate a strike-slip displacement with an earthquake. The longest segment, the Conway segment, shows evidence of past earthquakes, although none have been recorded since European settlement in about 1850. investigations show that at least 3 events have occurred, the most recent of which is dated as between 1720-1840 A.D.

Famous quotes containing the words seismic and/or activity:
“Most near, most dear, most loved and most far,
Under the window where I often found her
Sitting as huge as Asia, seismic with laughter,”
—George Barker (b. 1913)
“The animal is one with its life activity. It does not distinguish the activity from itself. It is its activity. But man makes his life activity itself an object of his will and consciousness. He has a conscious life activity. It is not a determination with which he is completely identified.”
—Karl Marx (1818–1883)
