Five new volcanoes erupt around the world: Red alert at Bogoslof (USA), eruptions at Reventador (Ecuador), strange lights above Popocatepetl (Mexico), Sabancaya (Peru), Kilauea (USA)

Five new volcanoes have erupted in the last two days around the world.

Bogoslof volcano in the US Aleutian Islands, Reventador in Ecuador, the Popocatepetl in Mexico, Sabancaya in Peru, and Kilauea in Hawaii, US.

NEW ERUPTIVE PULSE WITH ASH TO MORE THAN 11 KM IN THE BOGOSLOF ISLAND, ALEUTIAN ISLANDS, ALASKA.

After several days of calm, the data of the seismograph located 80 km away and the lightning detector show an important volcanic activity in the island. Alert Level changed to RED

Mar 8, 2017 08:40 – A significant explosive eruption began at Bogoslof volcano at 7:36 UTC on March 8 (10:36 pm AKST on March 7) as indicated in seismic, lightning, and infrasound data. Although at this time there have been no satellite images confirming eruptive activity, these monitoring data strongly suggest that significant ash emissions have occurred. Thus, AVO is raising the Aviation Color Code to RED and Alert level to WARNING.

ERUPTION OF REVENTADOR, ECUADOR

The volcano maintains its high activity. On March 6, 2017, the volcano erupted sending a plume of steam and ash was 1000 meters above the crater. No lahars have been triggered.

Meanwhile, 3 episodes of harmonic tremor harmonic, 2 episodes of emissions tremor, 25 long period events (LP) and 35 explosions were recorded at the peak.

ERUPTION OF KILAUEA , HAWAII

Kīlauea Volcano continues to erupt at its summit and at the Puʻu ʻŌʻō vent on its East Rift Zone. The episode 61g lava flow from Puʻu ʻŌʻō is entering the ocean at Kamokuna and is feeding surface flows on and above the pali, and on the coastal plain, inland from the ocean entry. These lava flows pose no threat to nearby communities at this time.

On Sunday morning, March 5, 2017, a small swarm of earthquakes began on the Upper East Rift Zone of Kīlauea Volcano. Sharp jolts from four earthquakes ranging in magnitude from 3.1 to 3.9 awakened residents between 6:06 and 6:17 a.m (Hawaii time). More than 90 smaller events have occurred since the initial shocks, all with depths of 2-3 km (1-2 mi) beneath the surface in the Devil’s Throat area southeast of Kīlauea’s summit between Hi‘iaka and Koʻokoʻolau Craters on the Chain of Craters Road in Hawaiʻi Volcanoes National Park.

This area of the Upper East Rift Zone is known for producing occasional earthquake swarms with the most recent prior one being in August 2016. The sizes and locations of the earthquakes suggest a source that may be related to either the ongoing pressurized magma storage system beneath the Kīlauea summit or regional tectonic stresses within the greater Kīlauea Volcano.

173 EXHALATIONS AND WEIRD LIGHT AT POPOCATEPETL , MEXICO

Over the past 24 hours, 173 low-intensity exhalations, accompanied by steam, gas and small amounts of ash, have been recorded. Six minutes of harmonic tremor of low amplitude have also been recorded.

During the night and morning, an incandescence appeared in the area of the crater that increased during some episodes.

19 ERUPTIONS PER DAY ON AVERAGE AT SABANCAYA VOLCANO, PERU

There was an average of 19 explosions per day, with maximum displacement values of 77 cm2. Since February 13, there is an increase in hybrid type earthquakes, which could indicate a rise in magma.

Eruptive ash and gas columns reached about 2800 meters above the edge of the crater and then spread over more than 40 kilometers north, northwest, and south of the volcano.

In general, activity has slightly increased since last week.
