whaleships cruised for right whales off the island between 1848 and 1892. Some went ashore nearby Jukdo to club pinnipeds. Geography Ulleungdo is a volcanic island that rose from the seabed between the third and fourth Cenozoic periods, and the part of the island is near the peak of the mountain. It is the summit of the longitudinal volcano, which was created by volcanic activity during the 3rd and 4th Cenozoic Era, and consists of trachyte, andesite, and basalt. Hot spot volcanic activity by the General Yi Sa-bu seamount, dissolved Simheungtaek seamount and Liancourt Rocks and Ulleung Island with An Yong-bok seamount was created as well. Liancourt Rocks is 4.6 million years ago estimated 2.5 million years ago, and the creation of Ulleungdo to us, 2.5 million years ago in 5,000 years ago. There is Seonginbong Peak in the center of the island. In the northern part of the island is the only flat basin, the Nari Basin. The Nari Basin was formed from caldera in the crater of the volcano, which was shaped like a Cheonji or Baekrokdam, but the water was drained and the soil was covered with stones and dirt on the bottom of the lake. There are 650 species of plants, including beech, cedar, and pine trees, and 50 species of birds, including black pigeons, and 340 species of insects. Tourism Favorite activities for tourists are hiking, fishing, and eating hoe (a Korean raw fish dish). Sightseeing boats make regular three-hour circuits about Ulleung-do, departing from the harbor at Dodong and passing by all the points of interest along the coast, including many interesting rock formations and the small neighboring island of Jukdo. Other scenic sites are Seonginbong, the highest peak on the island (); Bongnae waterfall; the "natural icehouse"; and a coastal cliff from which the Liancourt Rocks can be discerned in the distance. Climate Ulleung-do has a humid subtropical climate (Köppen climate classification Cfa), though it resembles the west coast of Japan much more than Korea, since in winter rainfall is heavy if less so than in such wet cities as Kanazawa or Akita. Sunshine is also very low in the winter if again not so markedly as in the previously-mentioned Japanese cities. Nature The island and surrounding water were registered as a marine protected area to secure rich biodiversity in 2014. As above mentioned, North Pacific right whales and pinnipeds were targeted by
