The Philippines constitutes an archipelago of 7,107 islands with a total land area of approximately 300,000 square kilometres (116,000 square miles). It is located between 116° 40', and 126° 34' E. longitude and 4° 40' and 21° 10' N. latitude and borders the Philippine Sea on the east, the South China Sea on the west, and the Celebes Sea on the south. The island of Borneo is located a few hundred kilometres southwest and Taiwan is located directly to the north. The Moluccas and Sulawesi are located to the south-southwest and Palau is located to the east of the islands.
The Philippines is divided into three island groups: Luzon (Regions I to V, NCR and CAR), Visayas (VI to VIII), and Mindanao (IX to XIII and ARMM). The port of Manila, on Luzon, is the capital city and the second largest city after Quezon City.
Most of the mountainous islands were covered in tropical rainforest and are volcanic in origin. The highest mountain is Mount Apo, located in Mindanao measuring at 2,954 metres (9,692 ft) above sea level. There are many active volcanos such as the Mayon Volcano, Mount Pinatubo and Taal Volcano. The islands are also located within the typhoon belt of the Western Pacific, and approximately 19 typhoons strike per year.
Located on the northwestern fringes of the Pacific Ring of Fire, the Philippines have experienced frequent seismic and volcanic activities. Around 20 earthquakes are registered daily, though most are too weak to be felt. The last major earthquake was the 1990 Luzon earthquake.
The longest river is the Cagayan River in northern Luzon. Manila Bay is connected to Laguna de Bay by means of the Pasig River. Subic Bay, the Davao Gulf and the Moro Gulf are some of the important bays. Transversing the San Juanico Strait is the San Juanico Bridge that connects the islands of Samar, and Leyte.
