    Tsunamigenic slope failure along the Middle America Trench in two tectonic settings (2004)
    Elsevier
    In:  Marine Geology, 203 (3-4). pp. 303-317.

    Description: Slope failure along the Costa Rica convergent margin commonly results from steepening of the continental slope above underthrust relief on the subducting plate. The 50-km-wide prehistoric Nicoya Slump was a big event that was followed by small slides from its headwall. Estimated maximum wave height above the slide is 27 m. The headwall occurs along a tectonized and unstable zone that extends northwest. An expected great earthquake in the adjacent Nicoya seismic gap could trigger future tsunamigenic landslides along this zone. The central Nicaragua slope, where the 1992 tsunamigenic earthquake occurred, has failed from steepening by tectonic erosion and perhaps subducting relief. The steep middle slope displays several large slide scars, each of which had the potential to generate a 6–7-m-high wave. A relation between the youngest slide and the 1992 earthquake is uncertain. Principal causes of landslides off Middle America were tectonic steepening and elevated fluid pressure. A mid-slope tectonized zone off Costa Rica allowed detachment of a huge slump involving the entire lower slope to the plate boundary. It may pose a hazard during rupture of the Nicoya locked zone.

    Megatsunami deposits on Kohala volcano, Hawaii, from flank collapse of Mauna Loa (2004)
    GSA, Geological Society of America
    In:  Geology, 32 (9). pp. 741-744.
    Details
    Publication Date: 2017-08-07
    Description: The origin of coastal and high-elevation marine gravels on the Hawaiian islands of Lanai and Molokai is controversial, because the vertical tectonics of these islands is poorly constrained. The gravels are either from eustatic highstands or were left by massive tsunamis from offshore giant landslides. In contrast, at Kohala on the island of Hawaii, where continuous subsidence is well established, lithofacies analysis and dating of a fossiliferous marine conglomerate 1.5–61 m above present sea level support a tsunami origin and indicate a runup of 〉400 m 〉6 km inland. The conglomerate age, 110 ± 10 ka, suggests a tsunami caused by the ca. 120 ka giant Alika 2 landslide from nearby Mauna Loa volcano.
