A volcano on the island of La Palma spewed lava and smoke, prompting an evacuation of thousands and forcing the Spanish prime minister to delay a trip to New York.
The EnVision spacecraft will complement two NASA missions announced last week, ending the relative loneliness of a planet sometimes thought of as Earth’s twin.
Mount Nyiragongo exploded on May 22, leaving hundreds of thousands of displaced people amid threats of new disasters.
Days after a deadly eruption of Mount Nyiragongo in Democratic Republic of Congo, the threat of another eruption forced the evacuation of much of the city of Goma.
After a night of panic and chaos that caused tens of thousands to flee their homes, officials in Goma cautiously declared the emergency over.
There was no immediate word on any casualties, but witnesses said that lava from Mount Nyiragongo already had engulfed one highway that connects Goma with a nearby city.
Stromboli’s volcano is always active, always at the brink of devastating paroxysms. For those who visit the island as tourists or scientists, it is a spectacle like no other.
La Soufrière, on the main island of St. Vincent and the Grenadines, last erupted in 1979, but recent activity had alarmed disaster management officials, who urged residents to evacuate.
No injuries were reported after the rare eruption near Reykjavik — only joy, on the part of the singer and other Icelanders.
The earthquake swarm is the culmination of more than a year of intense seismic activity. It could also herald decades of intermittent volcanic eruptions.

The civil defense authorities warned people to stay indoors to avoid the fallout of ash carried by the winds.
Government agencies and individuals were among those charged over the roles in the 2019 disaster, which killed 22 people.
With a few easy-to-find items, you can discover the archipelago’s breathtaking biodiversity, savor its flavors and music, even delight in an island-inspired Thanksgiving.
Not thought to be volcanically active, Mars may have experienced an eruption just 53,000 years ago.
Massive volcanic eruptions ignited oil and coal deposits in Siberia in the events that led to the Permian-Triassic “Great Dying” event.
In the abyss, everyone can hear you scream.
Maya civilization was blossoming into its golden age when a volcano erupted at the southern edge of the Maya region, in what is now El Salvador. Tens of meters of ash and debris buried the densely populated, fertile farming valleys around the Ilopango caldera. Aerosols blasted into the stratosphere by the eruption settled as far away as Greenland and Antarctica. While the wider Maya civilization was mostly unaffected, it took a century and a half for life to resume in the shadow of Ilopango.
In a recent study, Oxford University archaeologist Victoria Smith and her colleagues used tree rings from a stump caught in a pyroclastic flow, along with data from polar ice cores obtained more than 7,000km (4,300 miles) away. These dated the eruption to 431 CE, the early part of the Maya Classic Period. The date may help future archaeologists and climate researchers better understand the impacts of the eruption on Central America and the rest of the world.
Buried by Tierra Blanca Joven
Volcanoes make dangerous neighbors, but they have ways of drawing people close despite the risks. Fertile volcanic soils in the valleys of El Salvador supported dense populations in Maya villages and urban centers like Chalchuapa. By the beginning of the Maya Classic Period, around 250 BCE, the rulers at Chalchuapa had built temples and a ball court at the site. Artifacts found among the ruins reveal trade connections as far away as central Mexico.
The desolate beauty of the winemaking tradition on Lanzarote, the easternmost of the Canary Islands, is evidence of human resilience in the face of adversity.
Scientists have linked historical political instability to a number of volcanic events, the latest involving an eruption in the Aleutian Islands.
Roman writers described unusual weather and famines in the years following Julius Caesar’s assassination in 44 BCE, adding to the turbulence of the civil war that marked the transition from Republic to Empire. A recent study has now identified the culprit: a volcano 9,000km (6,000 miles) away in Alaska.
“Madness of wolves in winter”
“Madness of wolves in winter; in summer, no grain is harvested,” cried a voice from the Oracle of Apollo, in Delphi, in the months following Julius Caesar’s death. Ancient writers who survived the period describe cold weather, short growing seasons, and widespread famine around the Mediterranean, from Rome to Egypt. Throughout the empire, starvation led to disease and fueled growing civil unrest in an already turbulent time.
For years, modern historians have speculated that a major volcanic eruption might have been the culprit. An erupting volcano blasts sulfur dioxide high into the atmosphere. As the sulfur dioxide spreads out in the stratosphere, chemical reactions turn it into other sulfur compounds that reflect solar radiation, blocking the Sun’s light and warmth. Huge swaths of the planet turn colder, often continents away from the eruption.
Some researchers interpret a new timeline of some of the formation’s biggest eruptions as evidence that its activity is waning.
A planet heated by giant volcanic eruptions drove the earliest known wipeout of life on Earth.
Whether you like hiking, fishing, volcanoes, trees or even fossilized trees, there is a less-traveled and still awe-inspiring national park for you.
It’s been 40 years since the sideways explosion that changed volcanology forever.
The tensions we now face between science, politics and economics also arose before the country’s most destructive volcanic eruption.
Two earth scientists offered a new model to explain destructive activity in 2018, but a number of their colleagues aren’t buying it.
The location and characteristics of most of the world’s volcanoes can be explained with just two recipes for magma production. The melting point of rock depends on pressure, so hot mantle rock flowing up toward the surface can melt as the pressure drops. The addition of water lowers the melting point, too, so water-laden seafloor plates can trigger melt as they sink down into the Earth at subduction zones. These two facts generally explain both volcanoes along plate boundaries—like the Pacific Ring of Fire or the mid-ocean ridges—and those at hot spots like Hawaii and Yellowstone.
But when looking back through Earth’s history, there are plenty of volcanic weirdos that don’t seem to line up with the figures in a textbook. There are volcanoes in the interior of the Western US, for example, far from any relevant plate boundary or hotspot. A new study by Jianfeng Yang and Manuele Faccenda of the University of Padua examines another difficult-to-explain set of past eruptions, both east and west of Japan.
Oddities near Japan
Japan sits on a subduction zone, with the Pacific seafloor sinking downward beneath the island. That’s the cause of both Japan’s dangerous earthquakes and its volcanic peaks like Mt. Fuji. But a thousand kilometers to the west, in northeast China, there are remnants of old volcanism. And 600 kilometers to the east, there are more recent basalt seamounts at the bottom of the ocean.
