香港发现1.4亿年前古老火山

香港1.4亿年前爆发，之后沉入海底的古老火山如今上了头版头条。

Some 140 million years after it erupted and then toppled into the sea, an ancient super volcano in Hong Kong is making headlines.

Hong Kong government scientists on Thursday announced that it had located the super volcano - the first discovery of its kind in southeastern China - while surveying the area in southeastern Hong Kong. The volcano is now extinct and poses no threat to Hong Kong.

The newly-discovered High island Super volcano spurted out 1,300 cubic kilometres of ash about 140 million years ago, enough to blanket all of Hong Kong. The super volcanic eruption on the southeastern China seaboard would have produced a global environmental impact and could be related to the extinction of dinosaurs, according to a handout from Hong Kong’s Geotechnical Engineering office that conducted the research.
