My Blogs (olelog) are mainly based on my daily
reading of earth science news.
Here on whatonearth.olehnielsen.dk I try to weave
some of the pieces together to a greater whole with added background info.
The Burma Plate is a small tectonic plate or microplate located in Southeast Asia,
often considered a part of the larger Eurasian Plate. The Andaman Islands, Nicobar
Islands, and northwestern Sumatra are located on the plate. This island arc separates
the Andaman Sea from the main Indian Ocean to the west.

To its east lies the Sunda Plate, from which it is separated along a transform
boundary, running in a rough north-south line through the Andaman Sea. This boundary
between the Burma and Sunda plates is a marginal seafloor spreading centre, which
has lead to the opening up of the Andaman Sea (from a southerly direction) by
"pushing out" the Andaman-Nicobar-Sumatra island arc from mainland Asia,
a process which began in earnest approximately 4 million years ago.
To the west is the much larger India Plate, which is subducting beneath the eastern
facet of the Burma Plate. This extensive subduction zone has formed the Sunda
Burma Plate treated in Olelog
