This image shows the “flame” on the coastline environment of Banda Aceh, Nanggroe Aceh Darussalam Province, Indonesia.
In fact, it should be sedimentation process captured by Landsat 8 OLI sensor on October 11, 2013. As we can see from the image, there are two main streams empties in the Strait of Bengal.
There are many variables involve to create this “flame”, such as wind speed, pressure, sediments source, and bathymetry. To produce the image above, I employed MNF transformation and used 765 MNF band output for RGB color composite.
Another unique phenomenon
There is another interesting earth surface phenomenon on the northern part of the image. Large size of wave!
At first I thought this was related to an earthquake events, because in the northwestern part of the image there is a plate boundary (ridge in Andaman Sea). Then I was looking at the USGS earthquake database for an earthquake event with scale ranging from Mw 1, in accordance with the date of the acquisition, however I could not find any related earthquake event.
Then I compare the image with the bathymetry and I found the answer of the large waves. For more details please read the following paper:
Keyword of this phenomenon is:
1. Sea surface manifestations of internal solitary waves, and
2. Interaction of barotropic tides and bathymetry
The two images above, have informed us that rather than static our earth is completely dynamic and life.
