The document prepared by the Ministry of Foreign Affairs, the Government of Japan in November, 2015 ( for UN General Assembly stated as follows.

Tsunami are generated by sudden submarine topographic movement, such as:

Submarine volcanic eruptions;
Landslides near a coastline or at the bottom of the ocean; and
Submarine crustal deformations accompanying earthquakes.

WLF5 organize a special event for World Tsunami Awareness Day on 5 November 2020 during WLF5 as a part of Theme 5 Landslide Research Frontier.

The special event includes sessions for tsunamis induced by coastal and submarine landslides and also multi-hazard risk analysis and modelling of various types of landslide disasters linked with other hazards. Japan suffered a catastrophic earthquake-and landslide- and tsunami disaster which killed more than 15,000 persons in 1792 in the Shimabara Peninsula, Kumamoto Prefecture and Amakusa islands.

Landslide researchers, government officers which are working for the proactive response for landslide-induced tsunami disaster are invited, and the landslide-induced tsunami disaster risk assessment and the risk preparedness will be discussed from the long range aspect are invited and discuss the

Post-Forum Field Trip on 7- 9 November 2020 includes the visit to 1792 Unzen Shimabara landslide and Tsunami disaster area in Kyusyu island.  This mega-landslide was triggered by a nearby earthquake in the Mayuyama of the Unzen Volcano.
