here is the largest in historic Hawaii...
1868 Hawaii earthquake est7.9 worst damage was in Ka'u
"...Damage
Wooden houses were knocked off their foundations in Keaiwa, Punaluu Beach and Ninole, while thatched houses supported by posts in the same areas were torn to shreds. The earthquake demolished nearly every stone wall and house within the Kau district in an instant. At Waiohinu, a large stone church built by Reverend John D. Paris collapsed, and in Hilo the shaking destroyed the few stone buildings and most walls.
Tsunami
A tsunami was caused by coastal subsidence associated with reactivation of the Hilina slump, triggered by the earthquake. At Kapapala the land subsided by as much as 2 m and formerly dry land was flooded to a depth of 1.5 m. The tsunami on the Kau and Puna coasts caused major destruction at Honuapo, Keauhou and Punaluu. The greatest damage was caused at Keauhou, where a wave height of 12–15 m was reported. All houses and warehouses were destroyed and 46 people were drowned.
Many villages, such as Apua were never resettled.
Landslides
The earthquake triggered landslides over a wide area. The largest was a mudslide 3 km wide and 9 m thick, that swept down the flanks of Mauna Loa at Kapapala. It swept away trees, animals and people, causing 31 fatalities...."
