I will begin with the conjecture that the small town of ‘Mul Dwarka (translated as ‘Original Dwarka’) is a proxy and thus points to Original Dwarka that is now underwater.
The Location of ‘Mul Dwarka’ is south of Somanath, along the coast, in the modern state of Gujarath in western India.
This area is active seismic zone. Several earthquakes have affected this area for past few centuries, including recent 8+ Richter scale earthquake on 26 January 2001 CE.
On 16 January 1819, an 8.3 magnitude earthquake affected this area.
It is critical to note that these earthquakes lead to lot of subsidence (land going down/sinking) and elevation at other places. This seismic activity also leads to changes in the height of sea floors and not just land. All of these factors must be taken into account, along with sea level changes (MSL) while researching ancient historical events.
Various surveys, around the Gulf of Cambay (Khambat che Akhat) have picked up fault zones with elevation and depression of as much as 30 meters!
The Gulf of Cambay was formed by a major rift.
Dr. Rajendran of CEES- Trivendrum commissioned ‘paleo-seismic’ studies in this area. His excellent work led to identification and dating of ancient seismic events in this region.
The Major earthquakes events identified in this region are as follows:
(1) 7540 +/- 130 Years BP (appxorimately 5540 +/-130 BCE)
(2) 3983 +/- 150 BP (Before Present, with typically Present = 1950 CE)
(3) 2780 +/-150 BP
I want readers to note down the date highlighted in bold and its plausible relevance for my (originally proposed by Dr. P V Vartak) proposed date of 5525 BCE for the flooding/destruction of Dwarka.
