Researchers believe that the Weber Deep was formed when part of the Earth's crust broke off along a 120 km (75 miles) extension of a fault on the ring of fire, called the Banda Detachment. The break-off was caused by plate tectonics creating a back-arc basin rip in the ocean floor. In parts of Weber Deep there is no oceanic crust on the sea floor due to the rip. The rip is approximately 60,000 km2 (23,166 miles2). Researchers believe Weber Deep is the world's largest exposed fault on the ring of fire.
The fault along Weber Deep and the Banda Sea is still active. The most extreme event on the fault recorded was in 1629. A Richter magnitude scale 9.2 megathrust earthquake produced a 15-meter (49-foot) tsunami. For nine years after 1629 the area had aftershocks.
The closest land to Weber Deep is at the east end of the Banda Sea, surrounded by Watubela archipelago, Timor, Buru, Seram, Ambon and Kur Island. To the west of the Weber Deep is the Banda Volcanic Arc also called the Inner Banda Arc. The Manuk volcanic island is the closest to the Weber Deep in the Volcanic Arc. The floor of the Weber Deep dates to 3.0 to 0.5 million years old. This young sea floor was created by the eastward expansion (rip) of the Banda Sea. Weber Deep is about 450 km long running north to south.[2][3][4]
Weber Deep was found in 1929 by the 204-foot 1928 HMS Willebrord Snelliu (named after Willebrord Snellius) using an echo sounder on a Dutch oceanographic expedition to the Banda Sea from March 1929 to November 1930. Hilbrand Boschma (1893–1976) was Dutch zoologist on the expedition.[6][7] In 1951 a more in-depth expedition of Weber Deep and the Banda Sea was done on the Galathea Deep Sea Expedition from 1950 to 1952. The expeditions found on the Weber Deep sea floor deep sea sea cucumbers and aerobic bacteria.[8][9][10][11]
