Philippine Trench

The Philippine Trench is a deep-sea trench (also called a deep-sea trench) in the western Pacific Ocean, reaching depths of up to 10,540 m and a length of 1,325 km. It stretches east of the Philippines, from the Moluccan island of Halmahera (Indonesia) to the northeastern tip of Luzon. Its greatest depth is the Galathea Deep (10,540 m). This makes it one of the deepest trenches in the world, exceeding 10 km in depth.

Until 1945, the Emden Deep was considered the deepest point in the Philippine Trench, having been measured at 10,400 m in 1926 by the crew of the German cruiser Emden. In 1945, the crew of the US ship Cape Johnson located a depth of 10,497 m in this trench using sonar; this depth was subsequently named the Cape Johnson Deep after the ship. In 1951, the crew of the Danish research vessel Galathea discovered a 10,540 m deep spot, which has since been known as the Galathea Deep.

The three deepest points in the Philippine Trench:

• The Galathea Deep is an underwater depression in the western Pacific Ocean and, with a depth of 10,540 m, is the deepest point in the Philippine Trench. It was discovered in 1951 by the crew of the Danish research vessel Galathea and has since been known as the Galathea Deep. It lies at approximately 10°10' north latitude and 126°38' east longitude.
• The Cape Johnson Deep, sometimes simply called the Johnson Deep, is an underwater depression in the western Pacific Ocean and, with a depth of 10,497 m, is the second deepest point in the Philippine Trench. It lies at approximately 11° north latitude and 127° east longitude.
• The Emden Deep is an underwater depression in the western Pacific Ocean and, with a depth of 10,400 m, is the third deepest point in the Philippine Trench. It lies at approximately 9° north latitude and 127° east longitude.
