Kilauea: Leilani-Eruption in 2018 – Part 1

by

Kilauea’s Leilani-eruption took place on Hawaii and begun in May 2018. The lava lakes in the craters of Halema’uma’u and Pu’u O’o drained off through the east rift. A dyke intruded on the coastal plain near Pahoa. In Leilani-Estates more than 25 fissures opened. Lava fountains fed lava flows that reached the ocean. Several hundreds houses were destroyed. In this video you can see huge lava fountains.

Fuego in March 2018

by

In March 2018, I visited the famose volcano Fuego in Guatemala. I climbed the volcano together with Matin Rietze and spend one night in the camp on the flank of Acatenango. The highlight of the night was a shooting star over the top of Fuego.

Fuego and shooting stars

Eruptions of volcano Fuego in Guatemala. This footage shows a timelapse with eruptions and shooting stars above the volcano. The Fuego dominates the city of Antigua. It forms a double volcano with Acatenango. In 2018, pyroclastic flows caused destruction and claimed more than 300 lives.

Mayon: Eruption is getting weaker

by

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

by

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

by

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

by

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.
