#YellowAlert Issued Due To Increased #SeismicActivity At #MaunaLoaVolcano In #Hawaii

The alert level for the volcano has been raised to yellow two days ago. This doesn’t mean that an eruption is expected to occur in a near future, but acknowledges that the volcano is currently preparing itself for its next eruption, which will come, sooner or later, but currently without possibility to indicate a specific time frame.

The Hawaiian Volcano Observatory (HVO) reported that “for the past several months, earthquake and ground deformation rates at Mauna Loa Volcano have exceeded long term background levels. An eruption is not imminent and current rates are not cause for alarm. However, they do indicate changes in the shallow magma storage system at Mauna Loa.”

Violent #Explosions With #Eruption Column Rising 2 km, Triggering #Panic At #StromboliVolcano In #Italy

A series of at least two very large explosions occurred this afternoon at the volcano. They probably rank among the largest recorded at the volcanoes in decades.

At approx. 16:51, 16:54, and 17:03 local time, it seems that the the western (or otherwise the central) vent produced powerful eruptions (in particular the latter two), which ejected glowing bombs all over the summit area and produced an eruption column that rose approx. 3-5 km.

Hot bombs and lapilli falling in the vegetated slopes of the island caused a series of fires. Panic was reported to have broken out among some residents in the village of Ginostra (which is at only 2 km horizontal distance from the crater), but there are no reports of injuries.

A newspaper article mentioned that some tourists fled into the sea and there are talks about evacuation of the island, although the situation is not clear at the moment.

What is is clear is that this so-called paroxysm today was one of the largest events of its kind on the volcano not only during recent years, but decades. Fortunately, such sudden large explosions have been rare at Stromboli (on average one or two per year), but they not entirely unusual. Unfortunately, they are almost impossible to predict and pose a constant risk for anyone visiting the summit area.

According to local news, the eruption was preceded by an overflow of lava into the Sciara del Fuoco, which seems to have been associated with the first explosion at around 16:51 (see image), suggesting that they were the result of a sudden surge in magma supply.

Strong #Eruption Of #Ash At #Manam #Volcano In #PapuaNewGuinea

Just 2 days after the large eruption of Ulawun, another large explosive eruption occurred in Papua New Guinea today, this time from Manam volcano located on a small island north of the main land.

Earlier today, the more or less permanently active volcano had another of its not usual, short-lived, but very intense paroxysmal episode with lava fountaining occurred today, starting around 13:00 local time. An ash plume that rose to 50,000 ft (15 km) altitude. A few hours later, the ash plume became separated from the volcano and was observed drifting SW. VAAC Darwin issued a warning and mentioned that it was expecting the plume to dissipate within 12 hours above an area over the southern part of or south of Papua New Guinea (see attached graphics), i.e. around the time of this report.

Such paroxysm have occurred at the volcano relatively frequently, at intervals of few months during the past years, last on 14 May and 24 January 2019. In most cases, lava flows as well as pyroclastic flows have occurred. No reports about significant damage have been received. Local reports indicate heavy ash fall blocking out the sunlight.

A few hours after the onset of the strong eruption, activity decreased again to now weaker ash emissions to 15,000 ft (4.5 km) altitude.
