A significant eruption occurred at Indonesia’s Merapi volcano at approximately 06:55 UTC (13:55 local time) on January 21, 2024, producing a large pyroclastic flow that reached about 2 km (1.2 miles) from the summit. The eruption caused a large ash cloud and panic but no fatalities or injuries have been reported. The Alert Level remains at 3 (on a scale of 1-4).
New activity/unrest was reported for 6 volcanoes from January 10 – 16, 2024. During the same period, ongoing activity was reported for 14 volcanoes.
Recent volcanic activity in the Svartsengi area has led to continuous land uplift, although the exact rate is still being determined through GNSS measurements. Around 200 earthquakes, the largest measuring M1.4, have been recorded near the magma conduit since yesterday. Despite a reduction in earthquake frequency, significant risks, including ground collapse, remain for the nearby Grindavík area.
Recent discoveries of new small mud volcanoes in Trinidad’s eastern region have prompted local authorities to prepare evacuation plans, following a small eruption in the Cascadoux Trace area last week. Three homes closest to the new mud volcanoes were already evacuated.
A day after a new volcanic eruption started near the evacuated city of Grindavik, Iceland, authorities are reporting a reduced flow of lava. While it’s unclear how long the eruption will last, they warn new cracks may be appearing on the surface within the city in the next few days.
The Ambrym volcano in Vanuatu has transitioned from minor unrest to a minor eruption state over the weekend, leading authorities to raise the Volcanic Alert Level from 1 to 3 on January 14, 2024. The eruption is occurring inside the Benbow crater, with a designated Danger Zone B extending approximately 2 km (1.2 miles) around Benbow and 4 km (2.4 miles) around Marum craters.
Another eruption began south-southeast of Hagafell, Reykjanes Peninsula, Iceland at 07:57 UTC on January 14, 2024. The latest images show the lava flowing toward the town of Grindavik. The perimeter was about 450 m (1 470 feet) from the northernmost houses in the town around 08:40 UTC.
A glacial outburst flood has begun at Grímsvötn volcano, located beneath the Vatnajökull glacier in Iceland. In addition, the volcano was hit by a M4.3 earthquake on January 11 — the strongest since measurements began in 1991. Glacial outburst floods are known to increase the likelihood of volcanic eruptions. As a result, the Aviation Color Code for the volcano has been raised to Yellow.
New activity/unrest was reported for 4 volcanoes from January 3 to 9, 2024. During the same period, ongoing activity was reported for 17 volcanoes.
A man is missing after falling into a ground crack caused by recent volcanic activity on Iceland’s Reykjanes Peninsula. The incident occurred in Grindavik, a coastal fishing town near the site of a recent eruption, on Wednesday morning, January 10, 2024.
