Volcanoes are nature’s dramatic sculptors, known for their power to alter landscapes and ecosystems profoundly. Among the numerous volcanic events, the eruption of Mount Tambora in 1815 stands unparalleled in its global impact. This eruption, the most powerful in recorded history, drastically reshaped Mount Tambora itself, reducing its height by over 4,000 feet and creating …

Cataclysmic volcanic eruptions are rare but inevitable, and their potential global consequences make them a critical focus for preparedness. The 1815 eruption of Mount Tambora in Indonesia serves as a stark reminder of the devastation such events can cause. Tambora killed 90,000 people locally and led to severe global climate disruptions. The Northern Hemisphere experienced …
In January 2022, the Hunga Tonga-Hunga Ha’apai volcano erupted with record-breaking force, devastating the island, triggering evacuations, and resulting in fatalities. The sudden eruption left scientists searching for ways to better predict such events. Recently, researchers identified a seismic wave precursor—a subtle Rayleigh wave signal that traveled across Earth’s surface about 15 minutes before the …

Since 2021, the Reykjanes Peninsula volcanism has dramatically showcased nature’s raw power through multiple eruptions near Reykjavík, Iceland. This period has been especially significant due to the reawakening of the Fagradalsfjall volcano in March 2021 after approximately 800 years of dormancy. Subsequently, the area witnessed two more eruptions in 2022 and 2023, followed by four …

In recent years, the Reykjanes Peninsula of Iceland, dormant for 800 years, has seen a resurgence of volcanic activity, causing significant disruptions and raising concerns about long-term impacts. Since 2021, multiple eruptions have upended daily life in this densely populated region, prompting evacuations, power outages, and infrastructure damage. This resurgence has evoked memories of past …

Once a financially struggling nation, Iceland has astonishingly transformed into the 15th wealthiest country in the world per capita. This dramatic change is largely due to its innovative approach to energy production, particularly through geothermal power. Initially reliant on expensive fossil fuel imports, Iceland shifted its strategy following the 1970s global oil crisis, turning to …

Iceland is embarking on a groundbreaking venture into the geothermal energy potential of its magma chambers, poised to transform our understanding of renewable energy sources. The Geothermal Research Cluster (GEORG) in Reykjavík is leading this initiative, planning to drill into a magma chamber, an unprecedented move in geothermal exploration. This ambitious project is not just …

In 1986, Lake Nyos in Cameroon experienced a catastrophic “limnic” eruption, releasing a cloud of CO2 gas that tragically suffocated over 1,700 people and 3,000 livestock. This disaster prompted scientists and engineers to find ways to prevent similar events. Three years later, they started siphoning CO2 from the lake using initially a garden hose and …
The eruption of the Hunga Tonga-Hunga Ha’apai volcano in January 2022 had a profound impact on the stratosphere’s chemistry and dynamics. This event, one of the largest volcanic explosions ever recorded, injected an unprecedented 300 billion pounds of water vapor into the stratosphere, which is typically dry and home to the protective ozone layer. The …
Geoscientists have long thought that water – along with shallow magma stored in Earth’s crust – causes volcanoes to erupt. New research shows that gaseous carbon dioxide can trigger explosive eruptions.
