Stealth Volcanoes May Erupt Without Warning: New Study Reveals Why
            Scientists have long used clear warning signs like earthquakes and ground swelling to predict volcanic eruptions. But some volcanoes erupt without giving such clues, putting nearby people and air traffic at risk. These are called "stealth" volcanoes and now, new research from Alaska’s Veniaminof volcano may help explain why they stay so quiet before exploding.
A team led by Dr Yuyu Li from the University of Illinois studied Veniaminof one of Alaska’s most active volcanoes to find out why many of its eruptions give little or no warning. Their findings, published in Frontiers in Earth Science, reveal that conditions deep inside the volcano play a key role.
“Even with advanced monitoring, some volcanoes erupt suddenly, catching us off guard,” said Dr Li. “Many such volcanoes are located...
