A previously unknown filtering process inside some volcanoes can cause magma to shoot out like champagne from a bottle - and perhaps even make it easier to forecast when a volcano is about to erupt.
The Rev. Sereno Edwards Bishop mobilized ship captains to track the extraordinary sunsets appearing around the world after Krakatau erupted in 1883.
How do organisms survive extreme conditions – and how can their adaptations help us develop better technology?
People tell tales to explain what they see – centuries later, scientists try to map handed-down myths onto real geological events.
Sonar scans of the Indian Ocean floor south of Christmas Island have revealed a Tolkeinesque landscape of towering peaks, ashen uplands and ominous volcanic craters.
Toba eruption caused temperatures to plummet by up to 10°C in some regions – but not where most humans lived.
When borders reopen, take an Aussie road trip and explore the continent’s unique geology, from meteorites in the Nullarbor Plain to rock formations that are billions of years old.
Researchers used decades-old radar data and found that some low-lying areas of Venus’ crust are moving and jostling. This evidence is some of the strongest yet of tectonic activity on Venus.
Nyiragongo is one of the most dangerous volcanoes in the world because of its fast-moving lava. It can flow at a speed of about 100km per hour.
I look at fragments of the Earth’s mantle under a microscope to learn how fast molten rock moves from deep in the Earth to the surface. This can help us prepare for future volcanic eruptions.
National governments need to wake up to the volcanic risks posed by tectonic rifting around Mount Nyiragongo.
The eruption prompted the evacuation of about 20,000 people, with no casualties.
Huge volcanic eruptions were once believed to be the cause of mass extinctions on Earth. However, new research has found that super eruptions did not necessarily result in mass extinctions.
Research into the bodies of victims of the Vesuvius eruption show how pyroclastic flows affect the human body.
The rocks provide rare evidence of a time when Earth’s surface was a deep sea of incandescent magma.
The last time south-west Iceland experienced a turbulent period of earthquakes and volcanic eruptions was in the 1300s.
New research challenges the idea that Laki caused years of extreme weather in Scotland and has implications for how we deal with sudden, forced climate change today.
From far north Queensland to the southern tip of Tasmania, there is a common geological mechanism that links Eastern Australia’s volcanic history.
Indonesia has a warning system for tsunamis generated by earthquakes – but not volcanoes.
Volcanoes give lots of clues which help scientists work out if they are about to erupt.
