该署的土力工程师(近海岩土工程)邓丽君说，超级火山喷出的火山灰逾1.3万亿立方米，足以将香港每一吋土地铺上1.3公里厚的火山灰。

The department's soil force engineer(Offshore geotechnical engineering)Teresa teng said，Super volcano ash more than 1.3 trillion cubic meters，Hong Kong is enough to every inch of land on the shop 1.3 kilometers thick ash。

　　粮船湾超级火山原本直径约18公里，最后一次爆发是1.4亿年前，之后已变成死火山，现时大部分火山岩已被风化和侵蚀，只剩下残余部分。

Grain ship bay super volcanic originally diameter about 18 km，The last outbreak is 140 million years ago，After has become extinct volcano，Now most of the volcanic rock has been weathering and erosion，Only stump。

　　它的上部分是火山岩，由粮船湾伸展至果洲羣岛，覆盖西贡东部的大片土地，位于香港世界地质公园的西贡园区内。在港岛北部和九龙的花岗岩，就是它爆发后形成。而火山灰冷却凝固后形成石柱，在西贡万宜水库东坝和西贡东部大部分地方露出，组成香港地质公园的核心部分。

It is the part of the volcanic rock，The grain ship bay stretch to GuoZhou island group，Sai kung east covered much of the land，Hong Kong is located in the world geological park in the park, sai kung。In the Hong Kong island and Kowloon north of granite，Is it formed after the outbreak。And ash cooling solidification formed after the stone，In Saigon wanyi reservoir DongBa and sai kung east most local show，The Hong Kong geological park of the core part。

　　邓丽君表示，果洲群岛是六角形岩柱最多的地方，市民可租船沿岸观赏，但该处没有旅游设施和码头，港府并不建议游客上岸。

Teresa teng said，GuoZhou islands are hexagon pillars as most place，Public can charter coast ornamental，But it has no travel facilities and terminal，The government does not recommend that the tourists go ashore。

　　据估计，该火山与近代的破火山口，如菲律宾塔阿尔火山和印尼塔博罗火山等，属同一类别，但粮船湾破火山口的规模更大。

It is estimated that，The volcano and modern caldera，Such as the Philippines taal volcanic and Indonesia tower boluo volcanic, etc，Belong to the same category，But food ship bay caldera of larger。

　　这次是在华南东部首次发现古代超级火山，而华南东部沿岸地区，可能还有众多类似但未被发现的超级火山，它们活跃于1.8亿至8000万年前，而香港粮船湾破火山口只是其中之一。

This is in the south eastern first discovered ancient super volcanoes，And the south eastern coastal areas，There may be many similar but undiscovered super volcanoes，They are active in 180 million to 80 million years ago，While Hong Kong food ship bay caldera is just one of them。
