Introducing mud volcanoes The Lusi structure – a contraction of Lumpur Sidoarjo, meaning “Sidoarjo mud” – is an example of a geological feature known as a mud volcano. They form when a combination of mud, fluids and gases erupt at the Earth’s surface.
2022 was a busy year for volcanic eruptions with Hawaii's Mauna Loa and Kilaeau erupting simultaneously, along with Mount Semeru, Indonesia and the Hunga undersea volcano in Tonga.
Geologists found deposits of volcanic rock and ash farther out from ubehebe than at similar volcanic craters because of better preservation, suggesting that similar volcanoes may have wider hazard zones than previously thought.
It is important for tourists to properly prepare for excursions to see volcanic eruptions – by allocating sufficient time for their visit, wearing adequate footwear and clothing, and carrying emergency kits.
Hawaii’s Mauna Loa, the world’s largest active volcano, began sending up fountains of glowing rock and spilling lava from fissures as its first eruption in nearly four decades began on Nov. 27, 2022.
The objective of the training was to improve the understanding of emergency operators on volcano and seismic hazards in the Dominica context, in order to be more prepared.
Researchers have found that the composition of specific gases released from volcanic fumaroles (gaps in the Earth’s surface) can provide an indicator of what is happening to the magma deep below, and could forewarn of increased volcanic activity.
15 January 2022 the Hunga-Tonga-Hunga-Ha’apai volcano eruption was felt across the Pacific Ocean and beyond, releasing energy equivalent to hundreds of Hiroshima nuclear explosions and creating supersonic air pressure waves that were observed from space
