Learn about the causes, impacts and responses to the flank eruption of Mount Etna, Italy, from October 2002 to January 2003. Use the resources and activities on this page to produce a detailed case study of the eruption.

The Hunga Tonga-Hunga Ha'apai (HTHH) volcano (20.536°S, 175.382°W) is an underwater caldera volcano located ~70 km north-northwest of Tonga's capital, Nukualofa. Recent Surtseyan-style eruptive activity was observed in 2009, from 2014 to 2015, and from 20 December 2021 to 15 January 2022 (17). In the lead-up to the 15 January 2022 ...

Extreme rainfall triggered the 2018 rift eruption at Kīlauea ...

The science of volcanology advances disproportionately during exceptionally large or well-observed eruptions. The 2018 eruption of Kīlauea Volcano (Hawai'i) was its most impactful in centuries, involving an outpouring of more than one cubic kilometer of basalt, a magnitude 7 flank earthquake, and the volcano's largest summit collapse since at least the nineteenth century.

Kilauea's 2018 eruption shows how a volcano can act like ...

In early July 2017 IGN enhanced their Volcanic Surveillance Network at La Palma to include four GPS antennas, five seismic stations, and four hydrochemical groundwater control points. A seismic swarm of 68 events located on the southern third of the island was recorded during 7-9 October 2017. It was the first of a series of seismic swarms ...

The St. Vincent case provides an important demonstration of how these principles were integrated, complementing synoptic analyses of the state-of-the-art in volcano observatory crisis operations 6 ...

The authors argue that the world is unprepared for the global impacts of large-scale volcanic eruptions, which occur more frequently than previously thought. They propose more research and investment in forecasting, preparedness and mitigation of such events.

Each case study begins with a brief overview discussing the size and volume of ash dispersed where known or approximated. Specific impact & mitigation information is organized into the following categories (where it is reported): Agriculture - Plants & Animals - includes livestock, pastoral land, horticulture and forestry.

Learn about the features, processes and hazards of volcanoes from this study guide and case studies. Explore the examples of Arenal, Yellowstone, Mount St. Helens and more.

Investigations carried out as part of the USGS Volcano Hazards Program provide case studies of monitoring two of the world's most active and best understood volcanoes, Mauna Loa and Kilauea on the "Big Island" of Hawaii.Since 1980, the USGS has expanded its monitoring studies to include other volcanoes in the United States and, in cooperation with foreign scientists, in a few other countries.

Sakurajima Case Study. This case study has been developed to support students studying Edexcel B GCSE Geography. Japan is located on a convergent plate boundary where the Eurasian plate is subducted by the Pacific and Philipinnes plates, causing a series of volcanoes. Sakurajima, Japan's most active volcano, is located on the southern island ...

What the Taal Volcano 'worst-case scenario' could look like

Aviation. The 2010 eruption of Iceland's Eyjafjallajökull volcano had a huge impact on air travel, changing the assessment of risk by the aviation sector and catalyzing new lines of scientific investigation. Ash advisories derived from dispersion-model output were issued by the London VAAC, depicting the presence of ash over large parts of ...

Mount Nyiragongo is a composite volcano located in the east of the Democratic Republic of the Congo (DRC). The volcano consists of a huge (2km wide) crater, usually filled with a lava lake, and is only 20km away from the city of Goma. Nyiragongo is currently classed as active (2020). Nyiragongo is located on a divergent plate boundary where the ...

This timing suggests that volcanic CO 2 was the cause of the ... The study is the result of the world's first successful application of high-precision radiometric dating on climate records ...

Remote sensing observations indicate potentially even younger volcanism during the late Copernican era (<0.8 Ga) on the Moon, on the basis of the geomorphology and crater-counting chronology of some volcanic-like terrains, known as lunar mare ring-moat dome structures ().There is evidence of recent gas escape from the Moon's interior in the Aristarchus region, located about 600 km south of ...

One such lava tube has been confirmed on the moon for the first time, according to a recent study. Lava caves, formed from cooled lava flows underground, are found near shield, basalt volcanoes ...

Europe's most active volcano, Mount Etna, has been hitting the headlines recently after a series of spectacular eruptions. In Etna's first eruption of 2021, explosive lava fountains reached over 1500 m in one of the most amazing eruptions in decades. Mount Etna, located on the island of Sicily, has been largely dormant for the past two years.
