A five-metre high tsunami washed them away as it inundated Muntei Baru Baru, his remote community on the south-west coast of the Mentawai Islands.
Unlike the accident in the Ukraine, events at Fukushima in March 2011 were not the result of ineptitude but rather a massive natural disaster in the form of a deadly 15-metre high tsunami.
An estimated 40 cubic miles (167 cubic metres) of rock fell into the ocean in one go, resulting in an 800ft (244m) high tsunami wave that engulfed an island more than 30 miles away (48km).
Subsequently, three ∼ 40 meter high tsunami waves overwhelmed the village of Tjelle and several other local communities.
The PTHA for Fukushima Dai-ichi Nuclestimated Sthaton estheannualhat thexceedancexceedance of 10 m high tsunami was an order of 1 × 10−5, or return period of around 100,000 years [89].
The high tsunami risk is also confirmed by O'Loughlin and Lander (2003) who compile 53 reliable tsunami occurrences in the Caribbean region within the last 500 years of written history.
This phenomenon created a secondary cycle, with positive polarity, that was responsible for the high tsunami amplitude recorded at tide gauge stations located north of Soma Coast (Miyagi Central, Sendai Offshore, Sendai Port, and Sendai New Port stations).
However, the capability of the forests to withstand extremely high tsunami has controversially been discussed due to the fact that so far, there are no definite conclusions, particularly on the role of the coastal forests as an effective natural tsunami barrier.
Based on Sascha et al.'s ([2010]) study, some landslides 70 km off Padang (Western Sumatra, Indonesia) may generate tsunamis, and the yielding maximum run-up is about 3 m, while Padang with over 750,000 inhabitants exhibits high tsunami vulnerability due to its very low elevation.
The eruption also generated a 35-150 m high tsunami that devastated the north coast of Crete, 110 km away.
