Experts have recently unearthed the intact vestige of a crater near Ba Lang An Sea off Binh Son District of central Vietnam’s Quang Ngai Province.

The crater, believed to date back several million years, is around 30 meters wide.

The surrounding area spanning around 40 square kilometers boasts a rich ecological system which was formed by several eruptions, according to the archeologists.

The volcano’s earliest eruption is thought to happen around six million years ago, while the latest roughly 3,000 years ago.

The finding adds uniqueness to the sea and its vicinity, which, according to experts, is worthy of UNESCO recognition as a geological park.

Hundreds of antiques dating back to as far as the 10th century have been recovered from several shipwrecks in the sea off Binh Son District in 2013 and 2014.
