The present implementation aims to assess whether networks with fewer parameters can succeed in providing meaningful early warnings, discriminating between inundation or no inundation. Hence, some data pre-processing was performed based on two criteria. First, to determine the minimum length of the ...
The weather bureau(气象局)warns people over the radio and television when a tsunami is heading for land.These warnings have helped save many lives.(1) The Japanese word tsunami means ___. [ ] A. earthquake B. sea wave C. ocean water D. tornado (2) According to the passage...
Reliable statistics for weak tsunamis will likely advance our understanding of tsunami physics and generation mechanisms and, as a result, improve tsunami warnings and mitigate the catastrophic consequences of tsunami waves. Processing tide gauge data begins with a preliminary analy- sis involving de-...
Tsunami warnings were also issued for Japan's northernmost main island of Hokkaido and for parts of North Korea and Russia. Russian officials issued a tsunami alert for the island of Sakhalin, warning that areas across the island's west coast could be affected by the waves. A tsunami warning ...
The warnings are few. The signs are sudden. The ground shakes. The tide goes into reverse. A great roaring sound fills the air. And then… It strikes. Wave after wave of crashing, crushing water. And when it is over, nothing is left. A tsunami. ...
Although federal warning centers quickly detect potential tsunamis and issue warnings, false alarms and warning system limitations hamper their effectiveness. Some state and local emergency managers have raised concerns about false alarms--the 16 warnings issued since 1982 were not followed by destructive...
000 buildings and structures have been destroyed or damaged. The early warning system of Japan stopped many bullet trains, and many residents received texted warnings of the earthquake and tsunami on their mobile phones giving them time to evacuate. Figures 1 and 2 show exactly how destructive ...
The limited number of earthquake and tsunami observations along the Pacific offshore areas of eastern Japan resulted in magnitude underestimates, which caused underestimates in earthquake early warning and tsunami warning. Because it is now clear that near-field tsunami warnings that are based solely ...
Subsequent research showed that traditional knowledge of tsunamis, conveyed through a folk song, had enabled the inhabitants to understand the danger and come to safety [17]. In the Euro-Mediterranean area due to their long return times, tsunamis are a virtually unknown phenomenon, of which ...
[33] found that, compared to official warnings, social cues (e.g., seeing others evacuate) were directly responsible for the decision to evacuate during the 2004 Kii Peninsula Earthquake in Japan. Similar behaviors also have been witnessed in the Tohoku Earthquake and Tsunami, in which community...
