| Zusammenfassung |
| Increasing human activities along the coasts of the world provoke the
necessity to assess tsunami hazard from different sources (earthquakes,
landslides, volcanic activity). In this paper, we simulate tsunamis generated
by underwater volcanic explosions from (1) a submerged vent in a shallow
water lake (Karymskoye Lake, Kamchatka), and (2) from Kolumbo submarine
volcano (7 km NE of Santorini, Aegean Sea, Greece). The 1996 tsunami in
Karymskoye lake is a well-documented example and thus serves as a case study
for validating the calculations. The numerical model reproduces realistically
the tsunami run-ups measured onshore. Systematic numerical study of tsunamis
generated by explosions of the Kolumbo volcano is then conducted for a wide
range of energies. Results show that in case of reawakening, the Kolumbo
volcano might represent a significant tsunami hazard for the northern,
eastern and southern coasts of Santorini, even for small-power explosions. |
