被災地の上空写真を一刻も早く人々の手に（1）

震災直後、被災地に家族や知人のいる人々は、焦燥に駆られた。津波はどこまで及んだのか？　家は流されていないか？　Google は、人工衛星からの写真を提供することで人々の不安を少しでも和らげようとした。

日本311賑災捐款地圖 / Japan AID Map - See Where AID Went

JAPAN EARTHQUAKE AND TSUNAMI RELIEF

100% of all contributions received have been used exclusively to help people in Japan, supporting local Japanese organizations caring for the most vulnerable people affected by the earthquake and tsunami, with special focus on people with disabilities and the elderly.

$6 million from thousands of generous donors worldwide
$3.98 million in grants (66% of total funds raised) to 9 Japanese relief and recovery groups
4% of total funds raised spent on program management and oversight
$1.8 million (30% of total funds raised) earmarked to support the long-term needs of the most vulnerable people

THE EVENT

On March 11, 2011, a magnitude-9.0 earthquake and subsequent tsunami and nuclear disaster struck northern Japan, killing over 16,000 people and leaving at least 3,000 missing. More than 5,400 people were injured and over 34,000 people were evacuated. The earthquake and tsunami damaged or destroyed more than 900,000 buildings.

THE PARTNERSHIP

Immediately following the disaster, Direct Relief and the Japanese American Citizen’s League (JACL) established the Japan Relief and Recovery Fund, committing 100% of all contributions to be used exclusively to help people in Japan in the most productive, efficient manner possible.

NHK「天空地圖」系統使用在311大海嘯之後 / NHK Skymap Aerial Mapping System Used After 3/11 Tsunami in Japan

NHK「天空地圖」系統使用在311大海嘯之後

去年NHK開發的「天空地圖」系統，除傳送即時空拍影像外，另傳送直升機上GPS位置、攝影機放大倍率及鏡頭方向等資料，結合擴增實境 (Augmented Reality, AR) 技術、透過電腦套疊地圖資料，產生如 Google Earth 標記方式，於即時影像上顯示地名、車站、建物等名稱及符號。對於如日本311大海嘯後地表面目全非，在報導、調查上很方便標示出關係位置，該技術即使在夜間也很能清楚標定。(如下圖及短片)

NHK Skymap Aerial Mapping System Used After 3/11 Tsunami in Japan

Skymap, developed by NHK last year, superimposes map data, such as district, station and building names on aerial pictures taken from a helicopter in real time.

NHK currently uses this system to give instructions to news helicopters, and it was used in the aftermath of the tsunami last year to guide helicopter pilots around areas left visually unidentifiable.

NASA Finds 'Merging Tsunami' Doubled Japan Destruction - NASA Jet Propulsion Laboratory

Merging Tsunamis of the 2011 Tohoku-Oki Earthquake

NASA satellite altimeter data on the major and destructive tsunami generated by the March 11, 2011 magnitude 9.0 Tohoku-Oki earthquake off Japan's northeastern coast were used to confirm the existence of long-hypothesized "merging tsunamis" capable of traveling long distances without losing power. The NASA/French Space Agency Jason-1 satellite (top left) passed over the tsunami 7 hours and 30 minutes after the earthquake and was able to 'see' a large wave resulting from merging tsunami jets. The NASA/European Jason-2 satellite (lower left) passed over the region 8 hours and 20 minutes after the earthquake and observed the normal tsunami wave. In the figures on the right, the satellite-observed tsunami height data (red and pink lines) was confirmed by JPL computer model predictions (black lines) based on 1,200 measurements of ground displacement from Japanese GPS stations. The satellites cannot change their orbit or be directed to view specific events, but may, by chance, be able to observe ocean phenomena such as this.

311 日本大海嘯漂浮物將飄向美西岸 / Japan Tsunami Debris Sloshing Around The Pacific

俄羅斯船艦 STS Pallada 號於9月下旬回程中行經過太平洋中途島，發現了一批今年311日本大地震的漂流物 (離日2000離遠) ，有電視、冰箱、家具等，還包括被當時海嘯捲走的20英呎福島 (Fukushima)漁船。夏威夷大學國際太平洋研究中心 (University of Hwaii Mānoa International Pacific Research Center) 由於此實證比原先預期測還快，據此重新估測第一波漂流物預計今年冬季會抵達中途島環礁，不到兩年會到達夏威夷，三年內到達美國西岸。

Televisions, fridges and furniture pieces are heading for Hawaii, as a huge amount of debris from Japan’s earthquake sails across the Pacific.

Up to 20 million tons of debris from the earthquake in March is traveling faster than expected and could reach the U.S. West Coast in three years.

It could be the first official report of tsunami debris from Japan nearing Hawaii.

A new report coming from a Russian ship have UH researchers changing their predictions. Since the March 11th earthquake and tsunami, researchers have been predicting it would take about two years for the debris from Japan to hit Hawaii's west-facing beaches.

“We have a rough estimate of 5 to 20 million tons of debris coming from Japan,” said UH computer programming researcher Jan Hafner. An average of 10 million tons of debris, the same amount released into the north Pacific basin in one year, was dislodged and set adrift in one day.

“Hawaii is just in the path,” said Hafner. Since the disaster, Hafner has been watching and calculating that wave of debris on a specialized computer program that follows and analyzes the currents.

In September, he got a chance to meet with Russian senior researcher Nikolai Maximenko and his crew on the STS Pallada.

Crew members from the Russian training ship the STS Pallada "spotted the debris 2,000 miles from Japan," last month after passing the Midway islands, the Mail wrote. "They saw some pieces of furniture, some appliances, anything that can float, and they picked up a fishing boat," said Hafner. The boat was 20-feet long, and was painted with the word "Fukushima." "That's actually our first confirmed report of tsunami debris," Hafner told KITV.

Hafner and UH researchers predict the first wave of tsunami debris will hit Midway Atoll by this winter, then Hawaii in less than 2 years.

日本輻射地圖 / Japanese Radiation Levels on Google Maps

Safecast 於日本311強震後一週即建立起靜態及移動式監測網，目前已自政府及其他來源收集超過75萬點位監測資料並呈現在Google 地圖上，提供局部均值方塊圖(點擊Explore these readings 可看到詳細點位資料)及監測收集路線上所有點位輻射值並以顏色來區分不同強度。

Safecast was created one week after this year's Japanese earthquake in order to build a radiation sensor network of static and mobile sensors around Japan. So far Safecast has collected over 750,000 data points which they have made accessible through a number of useful Google Maps. The Safecast Map depicts a heat map of the radiation readings. It is possible to select individual squares on the map and view the average readings. Safecast have been driving across Japan in order to take radiation level readings. The data form each trip can be viewed on its own Google Map. The Safecast trips maps can be searched by location. In addition Safecast are aggregating radiation data from government and other sources. This data can be viewed on the Aggregate Map From All Sources.
