Lake Danao is a guitar-shaped lake on the island of Leyte, Philippines in the province of Leyte. The lake is covering an area of . It is situated in the Lake Danao Natural Park, which also includes the Amandiwin mountain range. The lake is northeast of Ormoc City, half an hour drive along the San Pablo - Tongonan and Milagro - Lake Danao roads. It was originally named "Lake Imelda" and was declared a national park on June 2, 1972 by virtue of presidential memorandum issued by then President Ferdinand Marcos. Later it was renamed and declared as Lake Danao National Park on February 3, 1998 through Proclamation No. 1155 and is now protected by Republic Act No. 7586 otherwise known as the National Integrated Protected Area System (NIPAS) Act of 1992.〔 〕 The lake supplies potable water to at least seven towns in Eastern Leyte including Tacloban City〔(Leyte Samar Daily Express Online ) Retrieved on 13 March 2009.〕 as well as the source of irrigation for ricelands in some municipalities like Dagami, Burauen, Pastrana and Tabon-tabon. At above sea level, Lake Danao lies on an altitude similar to Tagaytay, making the area cooler than the average Philippine temperature. ==Origin== The lake is volcanic in origin and is probably a ''graben'' or depression produced by the Philippine Fault (or Leyte Central Fault), an active fault traversing the lake area in a N-S direction. Rock formations of the surrounding mountains include andesitic volcanic rocks of Quaternary origin in the western side, andesitic and dacitic volcanics of Miocene origin in the southeastern portion, and intermediate volcanic sediments of Quaternary origin in the northeastern side of the lake.〔 There are wetlands found near the lake. The present lake could be the deepest portion of a much larger lake in the past. It was probably much larger in the geologic past and could have included the large wetlands and marshes. Sedimentation has probably transformed this portion of the lake into what it is today. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Lake Danao (Leyte)」の詳細全文を読む スポンサード リンク
