菲律賓瓦西颱風災害地圖 / Google Crisis Map - Typhoon Washi (Sendong)


瓦西(Washi)颱風在當地時間16號星期五深夜,夾帶著強風豪雨,引發大量洪水和土石流,沖進菲律賓南部民答那峨島的河濱與沿岸村莊,重創該島「卡加揚德奧羅」(Cagayan de Oro)和「伊里甘」(Iligan)等地,造成嚴重傷亡,摧毀1萬多間房屋並造成30多萬人流離失所,這些民眾如今大多待在緊急避難所。
菲律賓國家減災風險管理委員會(National Disaster Risk Reduction and Management Council)負責人拉莫斯(Benito Ramos)說,遠至菲律賓中部莫好島(Bohol)的漁民,都在幫忙打撈被沖到好幾百英里外的遺體。
拉莫斯接受廣播電台訪問時說:「只要海中有遺體,搜尋與打撈作業就會持續進行,甚至新年以後也是如此。」當局已經把搜索區域擴大到半徑300公里範圍。


Washi, known locally in the Philippines as Sendong, began as a tropical depression on December 13, 2011 in the West Pacific Ocean about 2150 km (~1333 miles) due east of the southern Philippines. Washi only intensified slightly and never exceeded tropical storm intensity as it tracked due west towards the southern Philippines’ island of Mindanao.

Washi made landfall on the east coast of Mindanao on the afternoon of Dec. 16 as a moderate tropical storm with sustained winds reported at 55 knots (~63 mph). Despite its modest intensity, Washi had a huge impact on the island. As Washi made its way across Mindanao, it dumped heavy rains over parts of the island, which in turn triggered flash floods and mudslides.

Rainfall estimates from the TRMM data are shown here for the period Dec. 13 to 20, 2011 for the southern Philippines. Storm symbols mark Washi's track. Rainfall totals are on the order of 200 to over 250 mm (~8 to 10 inches, shown in green and yellow) along Mindanao's east coast where Washi made landfall, but the highest amounts are along the northwest coast, where totals are on the order of 300 to over 400 mm (~12 to over 16 inches, shown in orange and red).

NASA’s Tropical Rainfall Measuring Mission (TRMM) satellite produced the image above late on December 15, 2011. In this image, it shows the tallest thunderstorms in the storm that reached around 15 kilometers or approximately 9.3 miles. The TRMM estimated only heavy rainfall located in the southwest quadrant of the storm early on December 15. By that evening, the storm had intensified and was showing rainfall estimates of at least two inches (50 mm) per hour in the east, north, and western quadrants. Some areas across the region, including Mindanao, saw rainfall totals you would typically see in a month in just one day. Everyone pays attention to the winds of a tropical system, but the biggest threat from any tropical cyclone is heavy rain, flooding, and storm surge.

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.

泰國洪水災害地圖 / Google Crisis Response - Thailand Floods 2011


Thailand Floods 2011

泰國遭遇50年來最大洪水災害。超過三分之二的國土都被淹沒,淹沒了稻田及關閉上百家工廠,而超過90萬家庭和企業都受到影響,並已有數百人不幸喪生。泰國救災工作目前集中在提供流離失所者必要的食品、清潔水和棲身之所和恢復受損的基礎設施。Google Crisis Response 設立泰國洪災地圖網站,提供緊急聯絡資訊並於地圖上顯示相關災害範圍、地點及避難所、捐助等資訊以利防救災。

Thailand is currently facing its worst flooding in 50 years. Flood waters have swamped more than two-thirds of the country, submerging rice fields and shutting down hundreds of factories while over 900,000 families and businesses have been impacted and hundreds of lives have been tragically lost. National relief efforts are now focused on providing essential food, clean water and shelter to displaced people and restoring damaged infrastructure to the Kingdom of Smiles.
