The Quill is a currently inactive stratovolcano in the southeast of the island of Sint Eustatius in the former Netherlands Antilles . At 601 meters above sea level, it is the highest point on the island and at the same time the second highest mountain in the entire Netherlands . The last eruption took place between 245 and 365 AD. The name Quill comes from the Dutch word kuil (meaning Kuhle , Loch ). Today the mountain is the tourist center of the island and has been part of the Quill / Boven National Park since 1998 .

Emergence

The volcano was formed about 22,000 to 32,000 years ago during rhyolite eruptions in a volcanic center about 200,000 years old under a shallow-water limestone bank , about three kilometers from what was then the southeast end of the island. The rock masses interspersed with limestone, carried by pyroclastic currents , accumulated at the edges and connected with the neighboring island to form today's terrain. The current crater is approximately 300 meters deep and approximately 760 meters in diameter. The Quill is a currently dormant but not extinct volcano. With the help of radiocarbon dating , the last eruption was dated to the years 245 to 365. Increases in temperature in the groundwater indicate further activity.
