Mayon: Eruption is getting weaker

Mayon’s eruptive activity has continued to decline in the last 24 hours. Yesterday morning (local time) 3 paroxysmal eruptions with lava fountains were observed feeding lava flows. During the day, the eruption has become more effusive again. Most likely, the lava dome grows again and there are still 2 lava flows active. Collapse events on the fronts of the lava flows caused debris avalanches.. A pyroclastic flow was observed. Seismic and sulfur dioxide emissions are at the level of the previous day.

Mayon is still active

The Mayon in the Philippines continues to be active, but activity has slowed in the last few hours. PHILVOLCS reports 5 episodes of sporadic lava fountains. These lasted between 7 minutes and 1.24 hours. Glowing tephra is 600 meters above the crater. The lava fountains increased lava flows which flowed through the gullys. In addition, pyroclastic flows, debris avalanches and rockfalls were observed. Sulfur dioxide emissions increase to 2,466 tonnes. Whether growth of the lava dome continued, was not communicated.

Mayon: strong phreatomagmatic eruption

The larger volcanic eruption of yesterday, was (according to PHILVOLC) of phreatomagmatic origin, took 8 minutes and promoted an ash cloud, which rose 5 km above the summit level. Pyroclastic flows (or pyroclastic density flows, as they are now called) have been created and flowed through various drainage channels. They reached lengths of 4 km. Volcanic ash rained down in several villages. Videos show that it got so dark that cars had to drive with light and barely had visibility. The local airport was closed and flights were canceled. This was the Mayon’s strongest eruption to date in the current eruption phase.

Mayon: eruption increased

At the Philippine volcano Mayon, the eruption has increased significantly in the last few hours. PHILVOLCS upgraded the alarm status from 3 to 4. The exclusion zone has been enlarged to 8 km. A further increase in activity is likely. A brief message states that explosions and lava fountains emanate from the lava dome. The seismic have increased significantly. The VAAC Tokyo reports volcanic ash at 9 km altitude. MIROVA registers a very high thermal radiation of 1019 MW. The biggest danger are pyroclastic flows.

Aerials of Campi Flegrei and Solfatara

Aerials, shot with a drone, of Campi Flegrei and Solfatara crater close to Naples in Italy. This volcano video was recorded in June 2017 with a DJI Phantom in 4K resolution.

Campi Flegrei is a huge caldera volcano, not far away from well known Mount Vesuvius. Campi Flegrei erupted before 39.000 years, which effected wide parts of Europe. Volcanic ashes were dicovered in distances of about 1500 km.

Masaya: Lava lake in Nicaragua

Masaya is a volcano close to Nicaraguas capital Managua. In the crater Santiago an active lava lake is boiling since December 2015. I visited the volcano with a team of the Volcanological Society e.V. and we get a permit to stay on the crater rim during day and night. So, I was able to shot this stunning volcano footage of a boiling lava lake.

About Masaya volcano

Masaya is not just the most active volcano of Nicaragua, its a very unusual one, too. The volcano lies within the Las Sierras shield volcano and is a 6 x 11 km caldera with walls up to 300 m high. The basaltic caldera is filled on its NW end by more than a dozen vents that erupted along a circular, 4-km-diameter fracture system. The twin volcanoes of Nindirí and Masaya were constructed at the southern end of the fracture system and contain multiple summit craters. One of this is the currently active Santiago crater. A lava flow from the 1670 eruption overtopped the north caldera rim. (Source USGS)

Colima: volcanic lightning

In November 2015 I captured this volcano footage from Colima in Mexico. Colmia was in a state of sporadic eruption from its main vent. The lava dome was blown out from explosions. So, instead of glowing avalances I observed volcanic lightning in the erupted ash clouds.

I traveled together with my colleagues from the Volcanological Society e.V. and meet with Hernando Alonso Rivera Cervantes who guided us. We rented a cabin, just 6 kilometers away from Colima’s summit.

More about Colima volcano

The Volcán de Colima is part of the Colima Volcanic Complex consisting of Volcán de Colima, Nevado de Colima and the eroded El Cantaro. It is the youngest of the three and is one of the most active volcanos in Mexico. It has erupted more than 40 times since 1576. 

During last years he activity was dominated by growth of an lava dome. In spring 2015 this dome was blown out by a series of explosions. Since then, explosive ash eruptions occur several time each day. This activity lasted several months. Then the explosions decreased and it began to grow a small dom again.
