Tsunami set off by volcano eruption kills 222 in Indonesia
A tsunami believed to be triggered by a volcanic eruption killed at least 222 people in Indonesia during a busy holiday weekend, sweeping away hotels, hundreds of houses and a group of people attending a beach concert.
More than 800 people were reported injured after the tsunami hit around the Sunda Strait at 9:27 p.m. Saturday, the Disaster Management Agency. At least 28 others were missing, but the toll could continue to rise because some areas had not yet been reached.
Scientists, including those from Indonesia’s Meteorology and Geophysics agency, said Sunday that the tsunami could have been caused by undersea landslides or those occurring above sea level on the Anak Krakatau volcano’s steep outside slope following the eruption. The volcano’s name translates to “Child of Krakatoa,” a volcanic island formed over years after one of the largest eruptions in recorded history occurred at the Krakatoa volcano more than a century ago. The scientists also cited tidal waves caused by the full moon.
LDOCEには “a very large ocean wave that flows over the land and destroys things” や “a very large amount of a particular kind of feeling or activity happening at one time” と定義されています。
tidalはtide /tάɪd/ の形容詞の形ですが、tideの語源は同英和辞典によると「元来は時の意。（海の潮）時から潮の意となった」と説明されていました。「きちんと片付いた、整頓された」という意味のtidy /tάɪdi/ もtideと同語源で「時にかなった、から、好ましい→きちんとした、になった」とありました。綴りも音も似ている語なので、関連付けて覚えておきたいです。（aqua）
