Seongsan Ilchulbong , also known as Sunrise Peak , is a 182 m high, volcanic land elevation in the east of the South Korean island of Jeju .
It has a crater depression, the bottom of which is 90 m above sea level and a diameter of approx. 600 m. Along with Mount Halla and the Geomunoreum-Lavaröhrensystem , the collection belongs to since 2007 World Heritage Jeju Volcanic Island and Lava Tubes of UNESCO .
Emergence
The information on the time of origin of Seongsan Ilchulbong is different and varies between a period from 5000 years ago to 120,000 years ago. What is certain, however, is that it originated from a hydromagmatic eruption in which magma came into contact with sea or groundwater. The water vapor released as a result smashed the surrounding rock and blasted a crater into the rock. A wall of ejected rock has then deposited around the crater.
classification
Due to the hydromagmatic explosion, the Seongsan Ilchulbong can be called a tuff cone. During the eruption , the volcanic material became wet and sticky from the water it came into contact with. This resulted in numerous deposits which are indicative of the wet nature of a tuff cone.
Ecosystem
Seongsan Ilchulbong can be divided into four areas: the inside of the crater, the north-western slope outside the crater, the stone cliffs on the outer crater wall and the sand dunes on the coast. Each area has a different vegetation.
A Flora of miscanthus and Artemisia princeps , also known as Japanese mugwort, as well as with Japanese arrow bamboo covers the inner part of the crater. The north-western slope is covered with the Japanese black pine and with evergreen bushes such as Orixa japonica or the ivy species Hedera rhombea . The stone cliffs are littered with ivy and star jasmine and the sand dunes are covered with silver hair grass and a flora of vitex and beach winds , a species of flora that is common near the sea.
