Iceland builds massive dykes to shield against volcanic lava flows

Iceland builds massive dykes to shield against volcanic lava flows

Icelanders build massive dykes to protect against lava flows from reactivated volcanoes near Reykjavik. The six volcanic systems, active for the first time in nearly 800 years, pose a significant threat to the Reykjanes peninsula, prompting around-the-clock construction efforts to safeguard homes and a crucial power plant.

Seismic activity and ground deformation surge at Kīlauea’s summit, Hawaii

Seismic activity and ground deformation surge at Kīlauea’s summit, Hawaii

Increased earthquake activity and signs of magma movement beneath Kīlauea’s summit, detected on January 31, 2024, have prompted the USGS Hawaiian Volcano Observatory to elevate the volcano’s alert level from ADVISORY/YELLOW to WATCH/ORANGE. With over 500 earthquakes recorded since midnight and ground deformation indicating pressurized magma chambers, the risk of an eruption remains high.

University of Iceland professor warns of lava flow proximity to Reykjavík

University of Iceland professor warns of lava flow proximity to Reykjavík

Þorvaldur Þórðarson, a volcanology professor at the University of Iceland, suggests that recent earthquakes in the Reykjanes Peninsula could indicate magma accumulation under Húsfellsbruna, raising concerns about potential lava flows near Reykjavík.

Slow lava eruption continues at Great Sitkin volcano, Alaska

Slow lava eruption continues at Great Sitkin volcano, Alaska

The Alaska Volcano Observatory reported a continuous slow eruption of lava in the summit crater of Great Sitkin Volcano as of 19:30 UTC on January 30, 2024. The Aviation Color Code remains at Orange and Alert Level at Watch.

Magma accumulation accelerates land rise near Svartsengi, Iceland

Magma accumulation accelerates land rise near Svartsengi, Iceland

In recent days, Svartsengi, Iceland, has experienced accelerated land rise, reaching up to 8 mm (0.3 inches) daily, attributed to magma accumulation under the area. While seismic activity remains mild, the risk assessment for Grindavík has been downgraded to orange, with a continued high risk for crack collapse.

Large pyroclastic flow at Merapi volcano, ashfall blankets nearby communities, Indonesia

Large pyroclastic flow at Merapi volcano, ashfall blankets nearby communities, Indonesia

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).

Grindavik faces significant risk of ground collapse due to fissures, Iceland

Grindavik faces significant risk of ground collapse due to fissures, Iceland

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.
