Eiby, G.A. 1980 The Marlborough earthquakes of 1848. Wellington: DSIR. DSIR Bulletin 225 82 p.
Abstract: Historical records show the Marlborough Earthquakes of 1848 to have been centred in the lower Wairau Valley. The principal earthquake, of estimated magnitude 7.1, occurred at 1-40 a.m. local time on Monday October 16, and was followed by a long and well-documented sequence of aftershocks. The shocks caused substantial damage to buildings in Wellington and Nelson, and ground subsidences and faulting in the Wairau. Earlier appraisals suggesting that the earthquakes were associated with movement of the Awatere Fault are based upon faulty historical information. Unpublished historical material is reviewed and presented, together with maps and present-day photographs of the region affected. (auth)
