Plateau and Coast Formed by the Eruption of Omuroyama Volcano

 Omuroyama (the light-brown hill at upper right of the photo) is one of the scoria cones of the Izu Tobu Volcano Group, which is an active terrestrial and submarine monogenetic volcano field located on and off the east Izu Peninsula. Omuroyama has a beautiful, pudding-like shape (1 km in diameter base, 300 m in height from the base) and a small (250 m in diameter) crater at the summit. We can easily enjoy the beautiful surrounding scenery from the summit of Omuroyama using a chairlift.
 The eruption of Omuroyama occurred about 4,000 years ago and its lava flows buried valleys and generated a lava plateau (Izu Kogen, a plateau at center to right center of the photo). Several lava flows reached Sagami Bay and formed a lava coast (Jogasaki Kaigan, a complicated coast at lower left to lower center of the photo). Along this coast we can see various lava structures, such as columnar joints and clinkers.
