Extent of shaking, North Canterbury earthquake, 1 September 1888

The Modified Mercalli scale (from 1 to 12) measures earthquakes by the intensity of shaking observed. Reports from historical records and diaries have been used to compile this map showing the extent of shaking during the earthquake of 1 September 1888. From an intensity of 9 close to the epicentre at Amuri, the isoseismal lines spread outwards. Although the most severe damage was in North Canterbury, there was considerable shaking in and around Christchurch.
