The physics of climate change runs on decades and centuries. Politics runs on the last hot summer. A new modeling study asks what happens when you wire the two together and let the short clock start…
A volcano rarely gives you six days' notice. Ruang, a 725-metre cone rising straight out of the sea in North Sulawesi, gave Indonesia's monitors almost exactly that in April 2024. This time, the…
Somewhere off the coast of Fogo, in the dark under two kilometres of Atlantic water, lies the wreckage of a mountain. Tens of thousands of years ago a whole flank of the volcano let go and slid onto…
When a fissure eruption begins on the Reykjanes Peninsula, it does not announce itself with a single mountain-top vent. The ground simply tears: a bright seam of fire opening across the lava field,…
Through the autumn of 2022, Ruapehu did everything a volcano does before it erupts — except erupt. Its summit crater lake, Te Wai a-moe, warmed through the year. Volcanic tremor climbed. Monitoring…
For as long as anyone had bothered to record it, Hayli Gubbi did nothing. It sat at the southern end of the Erta Ale volcanic range in the Afar depression, a low basaltic shield with no eruption in…
A volcano is never truly silent. Even when nothing erupts, the ground beneath a place like Askja hums with a faint, ceaseless vibration: ocean waves pounding a distant coast, wind dragging over rock,…
A volcano does not have to be quiet just because it is underwater. It bubbles, hisses, and occasionally coughs, and all of that makes sound. Sound travels well through water, better in many ways than…
Pick up a fist-sized stone from the ash country east of Naples, and you are holding a thermometer. It is not a precise one, and it stopped working around 40,000 years ago. But the magnetic minerals…
