G. Navarra Earth, Space, & Time i. 17/2 Subduction along the Java Trench where the Indo-Australian Plate is moving under the Indonesian island chain..fueled the 1883 eruption of Krakatoa. 1993 Jrnl.

Nearly Everything (2004) xix. 359 Zircons appear in most rocks apart from basalts and are extremely durable, surviving every natural process but subduction. Compounds subduction zone n. Geology a zone at or beneath the earth's surface at the edge of a crustal plate at which subduction (sense 6) is occurring, typically marked by the presence of an ocean trench and an island arc and/or chain of fold mountains; cf.

Amer. Nov. 89/2 The deepest trenches of the world's oceans, including the Java and Tonga trenches and all others associated with island arcs, mark the seaward boundary of subduction zones. 1989 Economist 23 Dec. 111/1 The pressure between the sinking crust and the overriding continent in the subterranean ‘subduction zone’ causes some of both plates to melt. 2004 Independent 27 Dec. 9/1 As tension gradually builds up in a subduction zone, a sudden jolt or slippage can occur resulting in the sort of earthquake experienced yesterday.
