Volcanic Generation of Tsunamis: Two New Zealand Palaeo-Events
(Springer International Publishing Switzerland, 2016-01-01)Rapid emplacement of a mass via pyroclastic flows, or edifice failure, generates volcanic tsunamis. Physical modelling demonstrates that the efficiency of tsuna-mi generation is influenced by the angle the mass enters the ... -
