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 Budj Bim, 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 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 year old (Ma) with the youngest only 7,000 years old.
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.
Scoria is a highly vesicular, dark-colored volcanic rock that may or may not contain crystals (phenocrysts). It is typically dark in color, and basaltic or andesitic in composition. Scoria is relatively low in density as a result of its numerous macroscopic ellipsoidal vesicles, but in contrast to pumice, all scoria has a specific gravity greater than 1, and sinks in water. The holes or vesicles form when gases that were dissolved in the magma come out of solution as it erupts, creating bubbles in the molten rock, some of which are frozen in place as the rock cools and solidifies. Scoria may form as part of a lava flow, typically near its surface, or as fragmental ejecta, for instance in Strombolian eruptions that form steep-sided scoria cones. Chemical analysis of scoria found in Yemen showed that it was mainly composed of volcanic glass with a few zeolites. Most scoria is composed of glassy fragments and may contain phenocrysts. The word scoria comes from the Greek σκωρία, skōria, rust. A colloquial term for scoria is cinder.
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 eruptions lasted for various periods ranging from a few weeks to several years. Rangitoto erupted twice; the first eruption 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. The field is currently dormant, but could become active again.
Tower Hill is an inactive volcano on the south-west coast of Victoria, Australia, approximately 275 kilometres (171 mi) west of Melbourne, and 15 kilometres (9 mi) north-west of Warrnambool. The Tower Hill crater is roughly 3 kilometres (2 mi) wide and 80 metres (260 ft) high, with a gradient of between 10% to 80% at the higher points. Within the crater, a series of later volcanic explosions formed a number of scoria cones and spheres, surrounded by a crater lake. Being a giant nested maar, Tower Hill is of international geological significance. The Dhauwurdwurrung name for the volcano is Koroitj.
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 face staring 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 local aboriginal dialect.
Mount Porndon is a 278-metre-high (912 ft) volcano located 13 kilometres southeast of Camperdown in western Victoria, Australia.
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. The park was established in 1987, and today encompasses 2800 hectares of land. The local Aboriginal name for the mount 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.
Matukutūruru is a volcano in Wiri, in the Auckland volcanic field. It had a scoria cone reaching 80 metres above sea level, which was quarried away. The lava flows created 290m long Wiri Lava Cave. The hill was the site of a pā. In late 2011 the quarry lake was drained and fill-dumping began on the site.
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, now used as a camping ground, and onto the rim which hosts a fire lookout, parking area and picnic ground.
