Another explosive eruption took place at Bagana volcano, Papua New Guinea at around 21:30 UTC on July 14, 2023, sending a discrete plume of ash and gas to 16.4 km (54 000 feet) above sea level. The Aviation Color Code remains at Orange.
A significant explosion occurred at Shishaldin Volcano in Alaska, U.S. at 09:09 UTC on July 14, 2023. The Aviation Color Code remains at Orange.
Volcanologists at the Alaska Volcano Observatory (AVO) are reporting increased activity at Shishaldin volcano. As a result, the Aviation Color Code was raised to Orange.
New activity/unrest was reported for 12 volcanoes. During the same period, ongoing activity was reported for 11 volcanoes.
A mud volcano erupted in Taiwan’s Pingtung County on July 11, 2023, ejecting steam and mud from several vents up to 2 m (6.5 feet) in the air.
Since its onset at 16:40 UTC on Monday, July 10, 2023, the eruption near Litli-Hrútur mountain on the Reykjanes Peninsula has seen a significant drop in intensity, with fewer and smaller lava fountains now compared to the initial stages.
After 6 days of intense seismicity between Fagradalsfjall and Keilir, Reykjanes Peninsula, Iceland, a new volcanic eruption has started just northwest of Litli Hrutur at around 17:00 UTC on July 10, 2023.
Since the onset of the seismic swarm in the Reykjanes Peninsula, on July 4, 2023, more than 8 500 earthquakes have been recorded in the area between Fagradalsfjall and Keilir. While seismic activity in this area is decreasing, deformation data strongly suggests that magma is rising toward the surface.
Shortly before midnight on July 6, 2023, a seismic sequence commenced close to Eldey Island on Reykjanes Ridge, approximately 10 km (6.2 miles) southwest off of Reykjanes Peninsula, Iceland. As a result, the Aviation Color Code was raised to Yellow.
10 days of continuous rainfall caused a large amount of volcanic material, debris and water to move down the slopes of the Semeru volcano on July 7, 2023, leading to destructive overflows and severe damage.
