Everything about Sunda Trench totally explained
The
Java Trench, also called
Sunda Trench, located in the northeastern
Indian Ocean, with a length of 2,600 km and a maximum depth of 7,725 meters (at 10°19'S, 109°58'E, about 320 km south of
Yogyakarta), was long thought to be the deepest
trench of the Indian Ocean, but it's in fact second to the
Diamantina Trench in the
South East Indian Basin.
The trench is a seam of
tectonic plates, the
Burma and
Sunda on the east, and the
India Plate on the west. Deformation along the plate boundary, or
subduction zone, resulted in the
2004 Indian Ocean earthquake and the ensuing deadly
tsunami on December 26, 2004.
There is scientific evidence that the recent earthquake activity in the area of the Java Trench could lead to further catastrophic shifting within a relatively short period of time, perhaps less than a decade
(External Link
). This threat has resulted in international agreements to establish a Tsunami warning system in place along the Indian Ocean coast

Exploration
Some of the earliest exploration of the Trench occurred in the late 1950s when
Robert Fisher, Research Geologist at the
Scripps Institution of Oceanography, investigated the trench as part of a world wide scientific field exploration of the world's ocean floor and sub-oceanic crustal-structure. Bomb-sounding, echo-train analysis and manometer were some of the techniques used to determine the depth of the trench. The research contributed to an understanding of the subduction characteristic of the Pacific margins.

Various agencies have explored the trench in the aftermath of the 2004 earthquake, and these explorations have revealed extensive changes in the ocean floor.

Oceanic Flight 815 in "
