Mount Napier in Victoria, Australia, is one of the youngest volcanoes in Australia. [2] It erupted about 32,000 years ago. [3] It was named by Major Thomas Mitchell after the three Napier brothers, who he had served alongside during the Peninsular War. Mitchell named it in August 1836, during his third expedition across south-eastern Australia. The local Aboriginal name for the mountain is Tapoc. [4] Mount Napier State Park is located 270 kilometres west of Melbourne and 17 km south of Hamilton.
Mount Napier, or Tapoc in the local Aboriginal language, has a composite lava shield with a superimposed scoria cone. The cone rises 150 metres (490 ft) above the surrounding plains to an elevation of 440 metres (1,440 ft), making it the highest point on the Western District Plains of Victoria. Mount Napier is part of the Newer Volcanics Province, which is the youngest volcanic region in Australia. The Newer Volcanics Province covers an area of 15,000 square kilometres (6,000 sq mi) and contains over 400 vents.
The Mount Napier Lava Flow followed the Harman Valley west from the volcano, and then south towards the nearby Mount Eccles which is 25 km south-west of Mount Napier. Lava blisters or tumuli occur along the flow - these are house-sized mounds of basalt rocks. The blisters are the best developed in Australia and uncommon in the rest of the world. They are formed by the pressure of liquid lava pushing up against the crust. [5] Several caves and lava tubes can also be found at Byaduk.
The native vegetation of Mount Napier State Park, on the western side of the mountain, varies from grassy woodland to tall open forest dominated by Manna Gum Eucalyptus viminalis, Blackwood Acacia melanoxylon, Austral Bracken Pteridium esculentum and Common Tussock Grass Poa labillardieri. [6] [2] This hosts a variety of native fauna, including birds, marsupials and mammals, including bats (Bird 1997 [6] ).
The Budj Bim National Park, formerly known as Mount Eccles National Park, is a national park located in the Western District of Victoria, Australia. The 5,470-hectare (13,500-acre) national park is situated approximately 270 kilometres (170 mi) west of Melbourne and approximately 15 kilometres (9.3 mi) southwest of Macarthur. It derives its name from the Budj Bim volcano, formerly Mount Eccles, which is situated in the north-east of the park.
The Undara Volcanic National Park is a national park in the Shire of Etheridge, Queensland, Australia. It is situated 275 kilometres southwest of Cairns just off the Gulf Developmental Road. The park was established in 2009 to protect Australia's longest lava tube and the unique fauna and flora found of the area. The basalts of the area form part of the Cenozoic McBride Basalt (Volcanic) Provence. The volcanics are all less than 8 million years old (Ma) with the youngest only 7,000 years old.
Rangitoto Island is a volcanic island in the Hauraki Gulf near Auckland, New Zealand. The 5.5 km (3.4 mi) wide island is a symmetrical shield volcano cone capped by central scoria cones, reaching a height of 260 m (850 ft). Rangitoto is the youngest and largest of the approximately 50 volcanoes of the Auckland volcanic field, having erupted in two phases about 1450 CE and 1500 CE and covering an area of 2,311 ha. It is separated from the mainland of Auckland's North Shore by the Rangitoto Channel. Since World War II, it has been linked by a causeway to the much older, non-volcanic Motutapu Island.
Mount Bachelor, formerly named Bachelor Butte, is a dormant stratovolcano atop a shield volcano in the Cascade Volcanic Arc and the Cascade Range of central Oregon. Named Mount Bachelor because it stands apart from the nearby Three Sisters, it lies in the eastern segment of the central portion of the High Cascades, the eastern segment of the Cascade Range. The volcano lies at the northern end of the 15-mile (24 km) long Mount Bachelor Volcanic Chain, which underwent four major eruptive episodes during the Pleistocene and the Holocene. The United States Geological Survey considers Mount Bachelor a moderate threat, but Bachelor poses little threat of becoming an active volcano in the near future. It remains unclear whether the volcano is extinct or just inactive.
Cinder Cone is a cinder cone volcano in Lassen Volcanic National Park within the United States. It is located about 10 mi (16 km) northeast of Lassen Peak and provides an excellent view of Brokeoff Mountain, Lassen Peak, and Chaos Crags.
Belknap Crater is a shield volcano in the Cascade Range in the U.S. state of Oregon. Located in Linn County, it is associated with lava fields and numerous subfeatures including the Little Belknap and South Belknap volcanic cones. It lies north of McKenzie Pass and forms part of the Mount Washington Wilderness. Belknap is not forested and most of its lava flows are not vegetated, though there is some wildlife in the area around the volcano, as well as a number of tree molds formed by its eruptive activity.
The Auckland volcanic field is an area of monogenetic volcanoes covered by much of the metropolitan area of Auckland, New Zealand's largest city, located in the North Island. The approximately 53 volcanoes in the field have produced a diverse array of maars, tuff rings, scoria cones, and lava flows. With the exception of Rangitoto, no volcano has erupted more than once, but the other eruptions lasted for various periods ranging from a few weeks to several years. Rangitoto erupted several times and recently twice; in an eruption that occurred about 600 years ago, followed by a second eruption approximately 50 years later. The field is fuelled entirely by basaltic magma, unlike the explosive subduction-driven volcanism in the central North Island, such as at Mount Ruapehu and Lake Taupō.
Penshurst is a town in Victoria, Australia. It is in the Shire of Southern Grampians local government area and is located at the foot of Mount Rouse, an extinct volcano. At the 2006 census, Penshurst had a population of 461. Basic facilities include a hospital with an aged care residency and doctor's surgery, a pub, a hall and two schools – one a State school, the other a Catholic school – the State school has 10 students(2020), the Catholic school 26.
Mount Schank is a 100 m (330 ft) high dormant volcano in the southeast corner of South Australia, near Mount Gambier. It was sighted by James Grant on 3 December 1800 and named after Admiral John Schank, designer of Grant's ship, HMS Lady Nelson.
Mount Elephant is a 380-metre-high (1,250 ft) conical breached scoria cone formed by a dormant volcano, located 1 km from the town of Derrinallum in southwestern Victoria, Australia. It is a prominent landmark that forms the eastern gateway to the Kanawinka Geopark from the Hamilton Highway at Derrinallum.
The Newer Volcanics Province is a geological area which is a volcanic field, formed by the East Australia hotspot across south-eastern Australia. It covers an area of 15,000 square kilometres (5,800 sq mi), with over 400 small shield volcanoes and volcanic vents. The area contains the youngest volcanoes in Australia.
Mount Noorat is a dormant volcano, situated on Glenormiston Road north of the township of Noorat, and approximately six kilometres north of Terang, Victoria, Australia. The last eruption is estimated to have occurred between 5,000 and 20,000 years ago.
The Glass House Mountains are a cluster of thirteen hills that rise abruptly from the coastal plain on the Sunshine Coast, Queensland, Australia. The highest hill is Mount Beerwah at 556 metres above sea level, but the most identifiable of all the hills is Mount Tibrogargan which from certain angles bears a resemblance to a gorilla facing east towards the ocean. The Glass House Mountains are located near Beerburrum State Forest and Steve Irwin Way. From Brisbane, the mountains can be reached by following the Bruce Highway north and taking the Glass House Mountains tourist drive turn-off onto Steve Irwin Way. The trip is about one hour from Brisbane. The Volcanic peaks of the Glass House Mountains rise dramatically from the surrounding Sunshine Coast landscape. They were formed by intrusive plugs, remnants of volcanic activity that occurred 26–27 million years ago. Molten rock filled small vents or intruded as bodies beneath the surface and solidified into land rocks. Millions of years of erosion have removed the surrounding exteriors of volcanic cores and softer sandstone rock.
Byaduk is a township in the Shire of Southern Grampians in the Western District of Victoria, Australia. European settlement began around 1853 by Wendish or Sorbian Lutheran immigrants who gave it the name Neukirch after the town in Saxony.
Mount Leura is a 313-metre scoria cone surrounding a dry crater 100 m deep and is the central and most obvious component of a larger volcanic complex southeast of the town of Camperdown located in western Victoria, Australia, 194 kilometres (121 mi) south west of the state capital, Melbourne. The inactive volcano is thought to have last erupted between 5,000 and 20,000 years ago. The name means "big nose" in the local Aboriginal dialect.
The Auckland Region of New Zealand is built on a basement of greywacke rocks that form many of the islands in the Hauraki Gulf, the Hunua Ranges, and land south of Port Waikato. The Waitākere Ranges in the west are the remains of a large andesitic volcano, and Great Barrier Island was formed by the northern end of the Coromandel Volcanic Zone. The Auckland isthmus and North Shore are composed of Waitemata sandstone and mudstone, and portions of the Northland Allochthon extend as far south as Albany. Little Barrier Island was formed by a relatively isolated andesitic volcano, active around 1 to 3 million years ago.
Mount Napier State Park is a state park in the Australian state of Victoria. It is 20 km northeast of Mount Eccles; its centerpiece is Mount Napier, a true volcanic cone, and one of the youngest volcanoes in Australia. The park was established in 1987, and today encompasses 2800 hectares of land. The local Aboriginal name for Mount Napier is Tapoc.
Mount Warrnambool is a single large scoria cone volcano that is 216 metres (709 ft) high. It is 16 kilometres (10 mi) southwest of Terang, Victoria, Australia. It is visible from the Princes Highway on the way to Warrnambool.
Budj Bim, also known as Mount Eccles, is a dormant volcano near Macarthur in southwestern Victoria, Australia. It lies within the geologically-defined area known as the Newer Volcanics Province, which is the youngest volcanic area in Australia and stretches from western Victoria to south-eastern South Australia.
Mount Franklin is an extinct volcano about 10 km north of Daylesford and 4.6 km south east of Franklinford in Victoria, Australia. A road spirals round the outside slopes covered with pine trees, into a flat 50 acre caldera, and onto the rim which hosts a fire lookout, parking area and picnic ground.
