Vietnamese archaeologists have discovered vestiges of an ancient volcano that they say dates back to six million years ago in the central province of Quang Ngai.
The vestiges are discovered near the beaches in Ba Lang An coastal area in Binh Son District, news website VnExpress reported.
Ba Lang An, literally means The Three Villages Named An, comprises of three villages - Van An, An Chuan and An Hai.
The mouth of the volcano could have been around 30 meters in width, according to archaeologists.
The terrain here is rather unique, with basalt soils and rock poles.
They said the geological structure in the area is similar to that of Ly Son Island in Quang Ngai.
They believed it was formed by volcanic eruptions millions of years ago.
Pham Quoc Quan of the National Heritage Council said the discovery of volcanic vestiges in the coastal central region is valuable.
The area should be nominated as a global geopark to UNESCO, he said.
Last October, divers and archaeologists discovered a 20-meter-long rock structure near the beaches in Quang Ngai’s Ly Son District.
Archaeologists said 70 percent of Ly Son Island’s area was formed by volcanic eruptions.
Some beautiful spots formed by volcanic eruptions in Ly Son such as Cau Cave, Hang and Duc Pagodas are believed to have great tourism potentials.
