Caulle Volcano Eruption, Chile - Francisco Negroni. Life Under the Volcano. Latacunga’s City Hall, in the heart of downtown, was quite literally built from the rubble of the city’s past destruction: it’s the only seat of government in the world constructed out of pumice—a rock formed by cooling lava.
Behind the pumice columns that hold up City Hall, which is now over 100 years old, sits the Department of Planning, where Patricio DeWitt, the city’s current Chief of Planning and Regulation, has been working on volcano-proofing the city. “We are going to grow the city west, away from Río Cutuchi,” he tells me, as we sit in his office. Dewitt explains that the city is going to invest in services such as water and electricity and build new schools in that area. *****California sleeping giants: High-risk volcanoes in California video.

New Lava Centre Exhibition For Iceland School trips to Iceland have grown in popularity in recent years, and I have been lucky enough to be regularly involved with some of them through my work with Rayburn Tours.
This summer I am looking forward to visiting a new interpretation centre called the ‘Lava Centre’ that is to open in the small village of Hvollsvollur. This convenient location is sure to benefit passing school groups, as it is on the main route (Highway One) that links a number of ‘must see’ locations on the south coast. The Lava Centre opens on June 1st, and promises to be Iceland’s largest volcano and earthquake exhibition.
It will feature interactive displays exploring the art, science and geology of the tectonic forces that have created Iceland itself. Bring it on!

During a volcanic eruption, lava, tephra (ash, lapilli, volcanic bombs and blocks), and various gases are expelled from a volcanic vent or fissure.
Several types of volcanic eruptions have been distinguished by volcanologists. These are often named after famous volcanoes where that type of behavior has been observed. Some volcanoes may exhibit only one characteristic type of eruption during a period of activity, while others may display an entire sequence of types all in one eruptive series. There are three different meta types of eruptions. The most well-observed are magmatic eruptions, which involve the decompression of gas within magma that propels it forward.
Within these wide-defining eruptive types are several subtypes. *****Taranaki NZ from space: "Volcanoes are one way Earth gives birth to itself." - Robert Gross Photo of New Zealand's Mount Taranaki volcano by space station crew. Cut-out 3D volcano model. A simple schematic model of the Eyjafjallajökull volcano summit, crater and ash plume as seen on Blue Peter's Make It.
It is intended as a simple guide to understanding how volcanoes such as Eyjafjallajökull are influenced by tectonic plate activity along the Mid-Atlantic Ridge. It also shows the route of the floodwater from melted glacier ice to the sea. The model is not to scale. Man swims dangerously close to lava zone in Hawaii.

Enormous dome in central Andes driven by huge magma body beneath it (cryptodome) A new analysis of the topography of the central Andes shows the uplifting of the Earth's second highest continental plateau was driven in part by a huge zone of melted rock in the crust, known as a magma body.
The Altiplano-Puna plateau is a high, dry region in the central Andes that includes parts of Argentina, Bolivia, and Chile, with vast plains punctuated by spectacular volcanoes. In a study published October 25 in Nature Communications, researchers used remote sensing data and topographic modeling techniques to reveal an enormous dome in the plateau. About 1 kilometer (3,300 feet) high and hundreds of miles across, the dome sits right above the largest active magma body on Earth. IMAGE: Japan's highest mountain, Mount Fuji, cutting through the clouds. New candidate for 'missing element' in Earth's core. Image copyright Science Photo Library Japanese scientists believe they have established the identity of a "missing element" within the Earth's core.
They have been searching for the element for decades, believing it makes up a significant proportion of our planet's centre, after iron and nickel. Now by recreating the high temperatures and pressures found in the deep interior, experiments suggest the most likely candidate is silicon. The discovery could help us to better understand how our world formed. Pahoehoe flows over A'a. Awesome science lesson in Hawaii. Ailsa Craig-the ghost island where Olympic curling stones are 'made' This tiny island, with its head poking out of the Firth of Clyde, is around 16 kilometers from mainland Scotland.
The island has the nickname “Paddy’s Milestone,” thought to have come about as the island is halfway on the sea-ferry route between Glasgow and Belfast. This route was followed by Irish laborers (paddy being an informal, sometimes derogatory, term for an Irishman) going to Glasgow to seek work. Formed as a plug in an ancient volcano, the small island has had a rather checkered history, especially considering its size. ***Drone close ups of volcanic eruption.

South Sandwich Islands: volcanic arc in a polar climate. The last time I wrote an article for Volcanocafe it was a guest post about the Galapagos Islands, but now I’m a new member of the Volcanocafe writing team (a little bit more about me later).
Deep in the South Atlantic Ocean lies an archipelago of uninhabited volcanic islands, the South Sandwich Islands. A British overseas territory located within the sub-Antarctic region. The South Sandwich Islands consists of 11 islands, they are Zavodovski, Visokoi, Leskov, Candlemas, Vindication, Saunders, Montagu, Bristol, Bellingshausen, Cook, and Thule all formed as a result of the subduction of a part of the South American Plate underneath the Scotia Plate as well as numerous seamounts. Because of the remote location of the islands and the volatile nature of the seas and climate, human expeditions are very rare so we have to almost always rely on satellite imagery for observations subject to weather.

Volcanoes might have forced early humans out of Africa, altering the course of our evolution. Réunion - Wikipedia. Réunion[discuss spelling] (French: La Réunion, pronounced: [la.ʁe.y.njɔ̃]; previously Île Bourbon) is an island and region of France in the Indian Ocean, east of Madagascar and 175 kilometres (109 mi) southwest of Mauritius.
As of 2014[update], it had a population of 844,994.[1] The island has been inhabited since the 17th century, when people from France, Madagascar and Africa settled there. Slavery was abolished on 20 December 1848 (a date celebrated yearly on the island), after which indentured workers were brought from South India, among other places.

A Trio of Plumes in the South Sandwich Islands. On September 29, 2016, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this false-color image (MODIS bands 7-2-1) showing volcanic activity in the South Sandwich Islands. Located in the South Atlantic Ocean, the uninhabited South Sandwich Islands include several active stratovolcanoes. Due to their remote location, these volcanoes are some of the least studied in the world, though satellites often catch them erupting.

Indonesia evacuates tourists after volcano eruption. Image copyright Reuters Indonesian authorities have evacuated some 1,100 tourists after a volcano erupted at one of the country's most popular hiking destinations. Mount Barujari on Lombok island erupted on Tuesday, shooting ash 2,000m (6,500 ft) into the air. Officials are still searching for several hundred tourists who remain missing, according to the country's disaster agency. There have been no reports of injuries caused by the eruption. Nearly 400 foreign and local tourists have been registered since Sunday to climb the mountain, according to the Disaster Mitigation Agency's spokesman Sutopo Purwo Nugroho.
