(A) Map showing the location of the 1855 landslide, Ruamahanga River, Kopuaranga, northern Wairarapa, and the trace of the 1855 earthquake rupture along the Wairarapa Fault. Shaded area of southern part of the Rimutaka Range represents the area of extensive landslide caused by the 1855 earthquake. Dotted area represents Pliocene sediments.
(B) Topgraphic and geomorphic map of the 1855 landslide area, 20 m contour interval, u = upthrown; d = downthrown side of the fault. Arrowed lines along fault indicate direction of horizontal movement. Ground slope between the fault strands is indicated by short arrowed lines.
(C) Geologic map of the 1855 landslide.
(D) Cross section of the 1855 landslide along line A-B in (C).
