INDONESIA : Tambora Volcano 1815,  the most devastating volcanic eruption on Earth in thousands of years !

In 1815, the faraway Indonesian island of Sumbawa was the site of the most devastating volcanic eruption on Earth in thousands of years. This extraordinary geological event took place 199 years ago today, and, on the cusp of its bicentenary, Tambora is finally getting…

New Evidence for Mantle Plumes as the source of Hot Spot Volcanism

New Evidence for Mantle Plumes as the source of Hot Spot Volcanism

In a recent study published in Science Magazine, the authors Colleen A. Dalton, Charles H. Langmuir, Allison Gale demonstrate geophysical and geochemical evidence for deep temperature variations beneath mid-ocean. Convection in Earth’s mantle is largely controlled by the physical properties of the mantle such as density and viscosity….

Indonesia (Java): Several explosions of the Merapi volcano

In its latest weekly report, the Global Volcanism Network indicates that Merapi has become active again with several explosions on March 9th that caused ashfall in several villages. Between March 14th and 20th, dense gas plumes rose up to 600 metres above the summit….

Using satellite imagery of volcanoes to monitor ground deformation and predict eruption!

Using satellite imagery of volcanoes to monitor ground deformation and predict eruption!

Using satellite imagery to monitor which volcanoes are deforming provides statistical evidence of their eruption potential, according to a new study led by the University of Bristol published today in Nature Communications. ESA’s Sentinel satellite, due for launch on April 3rd, should allow scientists…
