Depth Shallow

The Earthquake of 1876 April 11 is described in contemporary press reports as the heaviest shock ever experienced in Oamaru.  Descriptions of the shaking suggest the intensity reached MM7 there.  At Kakanui, the event was described as "very severe"  At Otepopo (near Herbert), large slips occurred from the cliff facing the river, suggesting that shaking reached MM7. Numerous slips were also reported between Otepopo and Hampden.  The earthquake is likely to have occurred at shallow depth, since felt aftershocks continued until at least the end of May.
