Elevated emissions of sulfur dioxide (SO2) at Vulcano volcano causes animal deaths and evacuations ordered in Eolian Islands, Italy

Due to elevated emissions of sulfur dioxide (SO2) from ground and finding dead animals, a small number of families has been evacuated from the village as reported volcanologist Marco Pistolesi on his twitter account.

The volcano observatory INGV raised the alert level for the volcano to “yellow” about two weeks ago, as increase of volcanic tremor and elevated fumarolic activity has been recorded.

Volcanic Alert Level Raised To Yellow – Elevated Fumarolic Activity At Vulcano Volcano, Eolian Islands, Italy

The observatory Istituto Nazionale di Geofisica e Vulcanologia (INGV) reported that elevated fumarolic activity in the Fossa summit crater has been detected today.

The activity is associated with increased level SO2 and CO2 emissions and temperature.

The seismic station recorded a small internal tremor related to near-continuous degassing over the past few weeks.

Based on the changes in the activity, the INGV raised the alert level for the volcano to “yellow”.

Alert Level raised to Yellow at Korovin Volcano in Andreanof Islands, Aleutian Islands

The Alaska Volcano Observatory (AVO) reported that the alert level for the volcano was raised to “yellow”, as an increase of seismic activity and sulfur dioxide emissions has been recorded.

The instruments record volcano-tectonic earthquakes over the past two weeks associated with sulfur dioxide (SO2) deggasing detected on 15, 20 and 26 October.

AVO will continue to monitor the volcano for signs of volcanic activity.

Taal volcano update: Eruption alert as 116 earthquakes hit Philippines volcano overnight #earthquake TaalVolcano #philippines

The volcano alert level for Taal is 3, meaning geologists are braced for an eruption in a matter of weeks. According to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), Alert level 3 represents a high level of volcanic unrest.

The alert is marked by sustained seismic activity, plumes of smoke belching from Taal as well as toxic gas emissions and the movement of magma underground.

On Friday, PHIVOLCS warned of 116 tremors were detected around Taal volcano in the 24 hours since midnight GMT (8am local time).

The Taal Volcano Network recorded, in addition, two low-frequency earthquakes, which could be a sign of molten rock entering the volcano.

PHIVOLCS warned: “These earthquakes signify magmatic activity beneath the Taal edifice that could lead to eruptive activity at the Main Crater.”

The agency warned the residents of Luzon Island to stay clear of the volcano in a 4.3-mile-wide radius.

Access to the danger zone is restricted in parts of Agoncillo, Laurel and Batangas.

According to the UN Office for the Coordination of Humanitarian Affairs, about 486,000 people have been affected by the erupting volcano since January 12.

On Friday, the fiery mountain sitting in the middle of Taal Lake was coughing up plumes of dirty steam and smoke.

The volcanic plumes were seen reaching heights between 1,640ft and 2,296ft, drifting in a southwest direction.

At the same time, PHIVOLCS said emissions of toxic sulphur dioxide (SO2) have dropped below instrumental detection.

Although eruptive activity has ceased since two blasts tore through Taal on January 12 and January 13 respectively, the volcano is still at risk of erupting.

Since January 12, Philippine Seismic Network (PSN) has recorded a total of 763 volcanic earthquakes around Taal.

The seismic activity was marked by fissures splitting the ground open on the southern parts of Luzon Island.

At least 177 of the quakes peaked at magnitudes between 1.2 and magnitude 4.2.

Between January 29 and January 31, the PSN recorded seven quakes between magnitude 1.7 and magnitude 2.5.

PHIVOLCS warned on Friday of more earthquakes, steam-driven eruptions, ashfall and lethal gases venting from the volcano.

The agency said: “DOST-PHIVOLCS recommends that entry into the Taal Volcano Island as well as into areas over Taal Lake and communities west of the island within a 7km radius from the Main Crater must be strictly prohibited.

“Local government units are advised to assess areas outside the 7km radius for damages and road accessibilities and to strengthen preparedness, contingency and communication measures in case of renewed unrest.

“People are also advised to observe precautions due to ground displacement across fissures, frequent ashfall and minor earthquakes.”

Riverside communities are at risk of lahars – fast-moving streams of mud, debris and volcanic ash mixed with water, particularly after heavy rainfall.

PHIVOLCS said: “Civil aviation authorities must advise pilots to avoid flying close to the volcano as airborne ash and ballistic fragments from sudden explosions and wind-remobilized ash may pose hazards to aircrafts.

“DOST-PHIVOLCS is closely monitoring Taal Volcano’s activity and any new significant development will be immediately communicated to all stakeholders.”

#Explosion at #PiparoMudVolcano Causes #Cracks to #Roads and #Homes in #Trinidad and #Tobago

A loud explosion was heard by residents at 10:08 PM, with cracks appearing across roads, & homes at 10:20 PM across Pancho Trace.

11:30 PM Update: Though there has been no confirmed eruption at the Piparo Mud Volcano, there are cracks on the roadway, one home has been damaged due to property cracks, a landslip, and a high sulphur smell according to MP Barry Padarath. He also added, there are no ongoing evacuations but residents are on standby.

New study confirms monster volcano Katla is charging up for an eruption

Katla, a giant volcano hidden beneath the ice cap of Mýrdalsjökull glacier, is busy filling its magma chambers, new research confirms. An eruption in Katla would dwarf the 2010 Eyjafjallajökull eruption, scientists have warned. The volcano is long “overdue” for an eruption, as it has historically erupted once every 40-80 years. The last known eruption in Katla was in 1918.

 

A group of Icelandic and British geologists have recently finished a research mission studying gas emissions from the volcano. The studies showed that Katla is emitting enormous quantities of CO2. The volcano releases at least 20 kilotons of C02 every day. Only two volcanoes worldwide are known to emit more CO2, Evgenia Ilyinskaya a volcanologist wit with the University of Leeds told the Icelandic National Broadcasting Service RÚV.  

 

These enormous CO2 emissions confirm significant activity in the volcano, Evgenia told RÚV: “It is highly unlikely that these emissions could be produced by geothermal activity. There must also be a magma build up to release this quantity of gas.”

 

She points out that more studies are needed to determine if the gas emissions from Katla are stable, or if they are increasing. “It is well known from other volcanoes, for example in Hawaii and Alaska, that CO2 emissions increase weeks or years ahead of eruptions. This is a clear sign we need to keep a close eye on Katla. She isn’t just doing nothing, and these findings confirm that there is something going on.”

 

The scientists also detected significant quantities of methane and hydrogen sulfite. These gases can be present in dangerously high quantities where the rivers Emstruá and Múlakvísl emerge from beneath the glacier.
