The 1996 Biak earthquake, or the 1996 Irian Jaya earthquake, occurred on February 17, 1996 at 14:59 local time (05:59 UTC) near the Biak Island, Indonesia. The earthquake had a magnitude of Mw 8.1. The run-up height of the generated tsunami reached 7 m.[1] 108 people were reported dead[2]. This earthquake was a thrust in a very oblique subduction zone. It ruptured at least 270 km along the New Guinea trench.[3] The slip distribution is very nonuniform. The largest slip was ∼12 m near the hypocentral depth (∼10 km), and the mean slip over a 230 km by 100 km fault area was 4 m.[4]
