High Island SuperVolcano
The volcano history was all started in High Island, Sai Kung of Hong Kong. In the Jurassic Period, which is about 160 million years ago from today, there is an 18km diameter long Ancient SuperVolcano located here. The High Island supervolcano's eruption occurred about 140 million years ago, left an indelible mark on Hong Kong's geology.
Eruptions of High Island SuperVolcano
Analysis of the resulting extrusive and intrusive igneous rocks reveals the immense power of this volcanic event, which affected nearly half of Hong Kong's total area. The impact is evident across Kowloon, Hong Kong Island, and Sai Kung, where volcanic remnants can still be observed today.
This single eruption shaped much of Hong Kong's current landscape, demonstrating the supervolcano's extraordinary strength and far-reaching influence on the region's geological formation.
