Mt Matavanu
Mount Matavanu is an active volcano on the island of Savaiʻi in Samoa. The volcano was formed during an eruption in 1905. Lava flows from the eruption covered a large area of land in the Gagaʻemauga district, leading to the relocation of several villages. The name of the mountain refers to a valley (''vanu'') with an eye-shaped feature (''mata''). In November 2022 Matavanu was recognised by the International Union of Geological Sciences as an international Geological Heritage Site. 1905 – 1911 eruption The eruption began on 4 August 1905, with a new crater being formed nine miles to the east of Mata o le Afi, which had erupted in 1902. An expedition led by governor Wilhelm Solf observed flames shooting 400 feet into the sky at intervals of ten seconds along with lava flowing through the bush. An expedition to examine the crater found "a larger heap of stones about 300ft high, from the top of which, at intervals of about 10 seconds, masses of stone were being thrown up into ...

Salamumu
Salamumu is a village on the south west coast of Upolu island in Samoa. The village has two settlements, Salamumu Uta (population 338) and Salamumu Tai (population 33). The village's name is derived from the words ''sala'' (fire) and ''mumu'' (punishment), and refers to its origin when people from Sale'aula were relocated to Upolu during the 1905—1911 eruption of Mt Matavanu. Although the village, area 13.11 km2, is geographically located on Upolu, the village is politically (and historically) part of the Gaga'emauga electoral district on the island of Savai'i. The people of Salamumu still have strong kinship cultural ties to their land on Savai'i. Le'auva'a is another settlement on Upolu island which was also relocated from Savai'i following the volcanic eruptions.

Volcanoes Of Samoa
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology."

Mountains Of Samoa
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are inselberg, isolated summits, but most occur in mountain ranges. mountain formation, Mountains are formed through tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosystems of mountains: different elevations hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Upolu
Upolu is an island in Samoa, formed by a massive basaltic shield volcano which rises from the seafloor of the western Pacific Ocean. The island is long and in area, making it the second largest of the Samoan Islands by area. With approximately 145,000 inhabitants, it is by far the most populous of the Samoan Islands. Upolu is situated to the southeast of Savai'i, the "big island". Apia, the capital, is in the middle of the north coast, and Faleolo International Airport at the western end of the island. The island has not had any historically recorded eruptions, although there is evidence of three lava flows, dating back only to between a few hundred and a few thousand years ago. In the Samoan branch of Polynesian mythology, Upolu was the first woman on the island. James Michener based his character Bloody Mary in ''Tales of the South Pacific'' (later a major character in the Rodgers and Hammerstein musical, '' South Pacific'') on the owner of Aggie Grey's Hotel on the so ...

Lava Lake
Lava lakes are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. The term is used to describe both lava lakes that are wholly or partly molten and those that are solidified (sometimes referred to as ''frozen lava lakes''). Formation Lava lakes can form in three ways: *from one or more vents in a crater that erupts enough lava to partially fill the crater; or *when lava pours into a crater or broad depression and partially fills the crater; or *atop a new vent that erupts lava continuously for a period of several weeks or more and slowly builds a crater progressively higher than the surrounding ground. Behaviors Lava lakes occur in a variety of volcanic systems, ranging from the basaltic Erta Ale lake in Ethiopia and the basaltic andesite volcano of Villarrica, Chile, to the unique phonolitic lava lake at Mt. Erebus, Antarctica. Lava lakes have been observed to exhibit a range of behaviours. A "constantly circu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
