Ringkasan geologi
The timing of the most recent activity in the Snæfell volcanic system, NE of Vatnajökull, is unknown. Four Holocene transitiional alkalic tephra units in a soild section near the volcano have compositions similar to known Snæfell eruption products (Oladottir and others, 2011). This stratovolcano is comprised of rhyolites and evolved basalts built in the last 400,000 years. Volcanic fissures trending NE-SW occur out to 10-18 km from the volcano. It lies on a volcanic belt outside the main volcanic zones. The Snæfell central volcano is Iceland’s highest volcanic peak outside of the large ice caps; it has a small glacier on its summit.
Ringkasan Wikipedia
Ringkasan InggrisSnæfell at 1,833 m (6,014 ft) high, is an ice-capped stratovolcano located in the north-east part of Vatnajökull National Park, Iceland. While it has been dormant in the Holocene, it is now known to have had repose times of over 100,000 years between eruptions, so it cannot be assumed to be extinct.
