Hunga Tonga-Hunga Ha'apai, an underwater volcano in the Tongan archipelago, erupted violently on January 15, 2022. According to a new study though, two faraway monitoring stations recorded a seismic wave some 15 minutes earlier.
After about 800 years without a volcanic event on the Reykjanes Peninsula, the Fagradalsfjall volcano epupted in 2021, 2022 and 2023. FGour more eruptions have taken place to the west at the Sundhnúkur fissure system in 2023 and 2024.
Morning images show frost briefly coating at least four colossal volcanoes: Olympus Mons, Arsia Mons, Ascraeus Mons, and Ceraunius Tholus.

Although more eroded and not as tall, the newly discovered volcano rivals the others in diameter. It’s about 450 km across. The volcano sits on the eastern edge of a broad rise called Tharsis, home to 3 other well-known giant volcanoes.
A volcanic eruption that has engulfed homes in an Icelandic fishing port confirms that a long-dormant faultline running under the country has woken up, threatening to belch out lava with little warning for years to come.
Icelandic scientists are embarking on a groundbreaking project to tap into a volcano's magma chamber for an abundant source of super-hot geothermal energy.
A study conducted by Hungarian scientists sheds light on the unpredictability and potential dangers of long dormant volcanoes.
Researchers unveiled megabeds formed by supervolcano eruptions in the Mediterranean Sea, offering insights into volcanic history.
That brings the total to 43,454 undersea mountains, almost doubling the number we knew about.
US scientists say they've found evidence of a volcanic eruption in data captured 30 years ago by the Magellan spacecraft.
An underwater volcanic eruption near the Pacific island of Tonga is the largest ever recorded by modern instruments, surpassing mid-century atomic bomb tests.
Although, scientists say there's little evidence that Yellowstone supervolcano is set to blow. The Yellowstone Volcano Observatory have maintained the danger level as green or normal.
Mauna Kea is classified as a dormant shield volcano. An U.S. team has found evidence that it has experienced over 1 million deep, long-period earthquakes over the past 19 years.
