The Izu–Bonin–Mariana (IBM) arc system is a tectonic plate convergent boundary in Micronesia.The IBM arc system extends over 2800 km south from Tokyo, Japan, to beyond Guam, and includes the Izu Islands, the Bonin Islands, and the Mariana Islands; much more of the IBM arc system is submerged below sealevel.
The backward motion of the subduction zone relative to the motion of the plate which is being subducted is called trench rollback (also known as hinge rollback or hinge retreat). As the subduction zone and its associated trench pull backward, the overriding plate is stretched, thinning the crust and forming a back-arc basin.
An individual trench can be thousands of kilometers long. [3] Most trenches are convex towards the subducting slab, which is attributed to the spherical geometry of the Earth. [21] The trench asymmetry reflects the different physical mechanisms that determine the inner and outer slope angle.
The CHIME telescopes in British Columbia detected the unusual fast radio burst, dubbed FRB 20240209A, in February 2024.

Ragnarok Online (Korean: 라그나로크 온라인, Rageunarokeu Onrain marketed as Ragnarök, and alternatively subtitled The Final Destiny of the Gods) is a massive multiplayer online role-playing game (MMORPG) created by Gravity based on the manhwa Ragnarok by Lee Myung-jin.
On the subducting side of the island arc is a deep and narrow oceanic trench, which is the trace at the Earth's surface of the boundary between the down-going and overriding plates. This trench is created by the downward gravitational pull of the relatively dense subducting plate on the leading edge of the plate.
