Philippines Table of Contents
Off the coast of eastern Mindanao is the Philippine Trough, which descends to a depth of 10,430 meters. The Philippines is part of a western Pacific arc system that is characterized by active volcanoes. Among the most notable peaks are Mount Mayon near Legaspi, Taal Volcano south of Manila, and Mount Apo on Mindanao. All of the Philippines islands are prone to earthquakes. The northern Luzon highlands, or Cordillera Central, rise to between 2,500 and 2,750 meters, and, together with the Sierra Madre in the northeastern portion of Luzon and the mountains of Mindanao, boast rain forests that provide refuge for numerous upland tribal groups. The rain forests also offer prime habitat for more than 500 species of birds, including the Philippine eagle (or monkey-eating eagle), some 800 species of orchids, and some 8,500 species of flowering plants. The country's most extensive river systems are the Pulangi (Rio Grande), which flows into the Mindanao River; the Agusan, in Mindanao which flows north into the Mindanao Sea; the Cagayan in northern Luzon; and the Pampanga, which flows south from eastCentral Luzon into Manila Bay. Laguna de Bay, southeast of Manila Bay, is the largest freshwater lake in the Philippines. Several rivers have been harnessed for hydroelectric power. ![]()
