Japan to develop emergency tsunami flash report system
TOKYO, Sept. 21 Kyodo -
Japan will develop an emergency flash report system to inform citizens of the arrival times of tsunami arising off Japan's Pacific coast to help them evacuate speedily, in light of the lessons learned from the March 11 earthquake and tsunami, officials said Wednesday.
The Ministry of Education, Culture, Sports, Science and Technology will seek 7 billion yen initially for the project as part of the current fiscal year's third supplementary budget, the ministry officials said.
Under the project, cables incorporating tsunami-measuring equipment will be laid on the seabed stretching from the area off Tokachi, Hokkaido, to that off Chiba Prefecture in the Boso Peninsula, surrounding the Japan Trench which is vulnerable to major quakes, they said.
Gauges with the functions of both a seismometer and water pressure meter will be developed so to estimate the heights of tsunami by measuring the intensity of seabed jolts and changes in water pressure, they said.
Hiromiki Terada, chief of the ministry's earthquake and disaster prevention department, said the ministry in collaboration with the Japan Meteorological Agency will aim to ''complete the new observation network within several years.''
The flash report system will instantly communicate data it collects to the weather agency and relevant research institutes to help speed up the agency's issuing of alerts from the current target of within three minutes and make them more accurate, the officials said.
At present, the government runs a network of 15 ground positioning system-based wave recorders located within 20 kilometers of shorelines around Japan to help the weather agency issue tsunami forecasts.
But it requires equipment in oceanic areas further away from the shores to detect the emergence of tsunami more speedily, they said.
