Volcanic eruptions and their ash clouds pose a significant hazard to population centers and air travel, especially those that show few to no signs of unrest beforehand. Geologists are now using a technique traditionally used in weather and climate forecasting to develop new eruption forecasting models. By testing if the models are able to capture the likelihood of past eruptions, the researchers are making strides in the science of volcanic forecasting.
When Kilauea Volcano erupted in 2018, it injected millions of cubic feet of molten lava into the nutrient-poor waters off the Big Island of Hawai'i. The lava-impacted seawater contained high concentrations of nutrients that stimulated phytoplankton growth, resulting in an extensive plume of microbes that was detectable by satellite.
The new 'universal break-up criterion' won't help with meltdowns of the heart, but it will help volcanologists study changing lava conditions in common volcanic eruptions.
A new study presents the detailed observation of a tsunami-generating volcano collapse by remote sensing. The study analyzes the 2018 collapse of Anak Krakatau, which triggered a tsunami that claimed over 430 lives and devastated coastal communities along the Sunda Strait, Indonesia.
Geologists have discovered that 50 million years ago a chain of volcanoes between Northeast Asia and Russia were forced into a period of dormancy that lasted for 10 million years.
To better understand subsurface processes associated with earthquakes and eruptions of Mount Aso, researchers investigated a very long period (VLP) seismicity dataset collected over two years. A new technique was developed to locate VLP events, and two clusters of such events were detected. Changes in the locations of VLP events were closely associated with earthquake and eruption occurrences. This method advances understanding of seismic and volcanic processes and could contribute to disaster mitigation.
Some volcanoes take their time -- experiencing protracted, years-long periods of unrest before eventually erupting. This makes it difficult to forecast when they pose a danger to their surrounding areas, but scientists are trying to change that.
Major volcanic eruptions spew ash particles into the atmosphere, which reflect some of the Sun's radiation back into space and cool the planet. But could this effect be intentionally recreated to fight climate change?
Scientists have devised a new method to forecast volcanic vent locations.
The molten rock that feeds volcanoes can be stored in the Earth's crust for as long as a thousand years, a result which may help with volcanic hazard management and better forecasting of when eruptions might occur.
More than half of the world's active volcanoes are not monitored instrumentally. Hence, even eruptions that could have rung an alarm can occur without people at risk having a clue of the upcoming disaster. A research project has led to a volcano monitoring platform which analyzes satellite images using - amongst other methods - 'artificial intelligence' (AI) for the monitoring of volcanoes.
The discovery of Tamu Massif, a gigantic volcano located about 1,000 miles east of Japan, made big news in 2013 when researchers reported it was the largest single volcano documented on earth, roughly the size of New Mexico. New findings conclude that it is a different breed of volcanic mountain than earlier thought, throwing into doubt the prior claim that it is the world's largest single volcano.
Some earthquakes along mid-ocean ridges are linked with low tides, but nobody could figure out why. In a new study, researchers have uncovered the mechanism for this seeming paradox, and it comes down to the magma below the mid-ocean ridges.
