When will the next eruption take place? Examination of samples from Indonesia's Mount Merapi show that the explosivity of stratovolcanoes rises when mineral-rich gases seal the pores and microcracks in the uppermost layers of stone. These findings result in new possibilities for the prediction of an eruption.
Imagine you're getting ready to fly to your favorite vacation destination when suddenly a volcano erupts, sending massive amounts of volcanic ash into the atmosphere, and forcing the cancellation of your flight. That's exactly what happened in April 2010 when Eyjafjallajokull, a volcano in Iceland, erupted and disrupted air travel in Europe for 6 days. Scientists are now using plasma physics to predict the characteristics of these hazardous ash plumes.
A recent study helps to better explain the processes in the Earth's interior beneath the Yellowstone supervolcano.
On 22 December 2018, a flank of the Anak Krakatau plunged into the Sunda strait between the Indonesian islands of Sumatra and Java, triggering a tsunami that killed 430 people. An international research team has now shown that the volcano produced clear warning signals before its collapse. The researchers recommend to use their study to improve monitoring of volcanoes.
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.
