Meru volcano (Tanzania) new eruption reported, first in 105 years

A new eruption has been reported yesterday from the volcano, which has last been active 105 years ago.

An ash plume was seen rising approx. 1 km and drifting NW from what looks like a lateral vent on the northern slope of the volcano near Arusha town. The are no reports of damage or fatalities.
According to local sources, people in the area around the volcano have been experiencing an increased number of small felt earthquakes in recent months.
Word trouwens ook gesuggereerd dat er daar een grote bosbrand gaande is.
Tis me niet duidelijk of dat een gevolg is van een kleine eruptie of dat die eruptie uberhaupt niet geweest is maar dat al die tijd het gewoon een bosbrand was?

Meru volcano (Tanzania): false eruption report - plume caused by forest fire
Monday Sep 21, 2015 19:17 PM | BY: T

The volcano is NOT erupting. The reported eruption turned out to be a false report - what seemed to be an ash plume was in fact caused by a huge forest fire on the slopes of Meru
ah :P

Alertlevel Mauna Loa Hawaii raised
HILO, Hawaii —Scientists at the U.S. Geological Survey Hawaiian Volcano Observatory have elevated the Volcano Alert Level for Mauna Loa from normal to advisory. This change in status indicates that the volcano is showing signs of unrest that are above known background levels, but it does not mean that a Mauna Loa eruption is imminent or certain.

HVO's seismic stations recorded elevated rates of shallow, small-magnitude earthquakes beneath the summit, upper Southwest Rift Zone, and west flank of Mauna Loa for at least the past year. During this same time, HVO monitoring instruments have measured ground deformation on Mauna Loa that is consistent with recharge of the volcano's shallow magma storage system. Together, these observations indicate that Mauna Loa is no longer at a background level of activity.

Based on these changes in activity, and in accordance with the USGS Volcanic Activity Alert-Notification System, HVO raised the Volcano Alert Level for Mauna Loa to advisory and the Aviation Color Code to yellow. The Volcano Alert Level is a four-tiered system that uses the terms Normal (background levels), Advisory, Watch, and Warning (highest threat) to inform the public about a volcano’s status. These alert levels are issued in conjunction with Aviation Color Codes, which provide information about volcanic-ash hazards to the aviation industry. The codes are Green (background), Yellow, Orange, and Red (eruption imminent).

An advisory/yellow status is declared when one or more volcano monitoring parameters are above the background range of activity, which is the current situation on Mauna Loa. Progression toward an eruption is by no means certain, but the volcano is closely watched to track how the unrest develops.

"It's possible that the increased level of activity at Mauna Loa could continue for many months, or years, without leading to an eruption," said Tina Neal, HVO’s Scientist-in-Charge. "It is also possible that the current unrest could be a precursor to the next eruption of Mauna Loa. But at this early stage, we cannot determine precisely which possibility is more likely."

HVO previously maintained an advisory/yellow status for Mauna Loa following increased rates of ground deformation during the rapid inflation of the volcano in 2004-2005. That period of inflation, similar to deformation currently observed, did not result in an eruption. When the inflation slowed to background levels in early 2010, the status of Mauna Loa was returned to normal/green.

The most recent eruption of Mauna Loa, which began on March 25, 1984, and lasted just over three weeks, was preceded by up to three years of increased earthquake activity. But, in contrast to pre-1984 activity, the energy released by recent earthquakes remains comparatively low.

HVO continues to closely monitor Mauna Loa, and will notify Hawai'i County Civil Defense, the National Park Service and other emergency managers, as well as the public, if significant changes are detected.
prachtig O+
volgens mij is dat uit die vulkaan in Chili?

Daar zijn weergaloze plaatjes van O+

Veniaminof volcano (Alaska, USA): alert level raised due to increased seismic activity

Seismic trace of Veniaminof volcano, VNH station (AVO)
Over the past day, seismicity at Veniaminof has increased and is ongoing in the form of volcanic tremor, the Alaska Volcano Observatory (AVO) reported.
The Aviation Color Code was raised to Yellow and the Volcano Alert Level to Advisory.

Reizigers die vandaag met KLM van Amsterdam naar Bali vlogen, zijn gestrand in Singapore. Het is te gevaarlijk om te vliegen door de grote aswolk uit de vulkaan Rinjani.

De vulkaan staat op Lombok. Dat eiland ligt vlak bij Bali, waar een van de grootste vliegvelden van Indonesi ligt, Denpasar.

De Rinjani spuwt al dagen zoveel as, dat vliegtuigen gevaar lopen. "Hoeveel passagiers er zijn gestrand weten we niet. Maar gestrande reizigers worden opgevangen in hotels", laat een woordvoerder van KLM weten.

KLM wil morgen pas beoordelen of ze weer gaan vliegen.
Tienduizenden toeristen vast op Bali na vulkaanuitbarsting

De luchthaven van het Indonesische Bali schrapt bijna zevenhonderd vluchten vanwege de uitbarsting van de vulkaan Rinjani op het nabijgelegen eiland Lombok. De as die de vulkaan uitspuwt, maakt vliegen onmogelijk.

De luchthaven van Denpasar is een van de drukste van Indonesi. De luchthaven blijft in elk geval tot morgenochtend dicht. Daarna wordt de situatie herbekeken, aldus een woordvoerder van de luchthaven. De vulkaan kwam afgelopen weekend tot leven. Tienduizenden toeristen zijn gestrand door de stremming op de luchthaven.
Was dat in Juli/Augustus/September ook al niet zo dat er tigzoveel mensen niet konden vliegen vanwege vulkanische activiteit op Bali? Was dat dezelfde vulkaan?

The one and Only!
4 jaar geleden daar nog gelopen, prachtig gebied rondom de Rinjani. Het is overigens volgens mij officieel niet de Rinjani zelf aangezien die ontploft is ergens rond 1200. In de krater van de ontploffing is een kratermeer ontstaan (Segara Anak), in dat kratermeer is vervolgens weer een vulkaan ontstaan. Weet niet of die vulkaan officieel ook Rinjani heet of een andere naam heeft. Op onderstaand plaatje is dat goed te zien

Kanlaon Volcano spews ash; no injuries reported

ANLAON Volcano in Negros region on Monday night spewed ash that reached 4,921 feet (1,500 meters) above its summit.
The minor ash eruption started at 9:55 p.m. and ended at 10:03 p.m., according to a notification by the Philippine Institute of Volcanology and Seismology (PHIVOLCS).
Rumbling noise was heard in Barangay Mananawin and Sitio Upper Pantao, Barangay Pula, Canlao City in Negros Oriental province as the volcano ejected ash.

Kanlaon Volcano, which has an elevation 2,435 meters, has erupted 26 times, making it one of the most active volcanoes in central Philippines.
The initial report did not mention any injuries or damage to property.
Philippines raised to level 1 alert after steam explosion at summit. 4 km radius permanent exclusion zone.

Seismologists watching Glacier Peak after four earthquakes

Four earthquakes struck within hours of each other Wednesday afternoon near Glacier Peak in Washington.

The first two earthquakes registered at magnitudes 3.1 and 3.5.

The first earthquake occurred at 12:11 p.m. The second registered roughly an hour later at 1:20 p.m.

Then a third earthquake — a magnitude 1.6 — occurred at 2:33 p.m.

And finally a fourth earthquake — a magnitude 1.4 — was registered at 3:44 p.m.

All the quakes were recorded roughly 19-21 miles east-southeast of the town of Darrington.

Seth Moran, geophysicist at the University of Washington, tells KIRO Radio they're keeping a close eye on the area and continue to watch the seismic records.

"Magnitude 3 earthquakes happen in Washington and Oregon a number of times per year," Moran said. "The one thing that makes these potentially interesting in a different way is they're somewhat close to Glacier Peak."

The quakes, about three miles from Glacier Peak, occurred where there haven't been a lot of magnitude 3 earthquakes in the past, according to Moran.

"The last time there was a magnitude 3 in the vicinity was in 1991," Moran said.

However, there isn't a great network of seismic instruments in the area.

There have been no reports of damage or injuries.

According to the USGS, the last time Glacier Peak erupted was 1,100 years ago. Mount St. Helens and Glacier Peak are the only volcanoes in Washington state that have been explosive in the past 15,000 years.

Ik heb een jaar of 12 geleden de Fuego zien uitbarsten toen we op rondreis Antigua aandeden. Indrukwekkend! Sowieso heel bijzonder om een vulkaan te zien uitbarsten (wanneer je op veilige afstand staat).

Nee, helaas. En ook destijds niet een camera die daar een redelijke foto van kon maken.

People evacuated after eruption Mt. Egon
MORE than 1,200 people have been evacuated from their homes to escape a gurgling volcano in eastern Indonesia spewing clouds of ash and toxic gas into the air.

Officials said they had distributed thousands of gas masks to villagers around Mount Egon in eastern Flores island as the choking fumes from the volcano intensified.

All residents within three kilometres of the volcano were ordered to evacuate and roads were also closed. Authorities said they were prepared to issue a wide-scale evacuation order if the situation deteriorates further.

“We are on a high alert and ready to evacuate any time,” disaster mitigation official Silvanus Tobi told AFP.

The volcano is popular with tourists, but it is unknown if any were near the volcano at the time it began erupting.

The volcano began rumbling last month but has become more active in recent days, sending villagers fleeing from their homes.

During its last serious eruption in 2008, Mount Egon blasted smoke and volcanic material nearly six kilometres into the atmosphere.
It is one of 129 active volcanoes in Indonesia, which sits on the Ring of Fire, a belt of seismic activity running around the basin of the Pacific Ocean.
El Misti: Showing signs of activity
For the first time in more than 500 years, Peru's El Misti volcano is showing signs of potentially eruptive activity.

According to the committee charged with volcanic risk management for the region of Arequipa, El Misti is one of a dozen potentially active volcanoes in Peru but its proximity to a million residents have the officials concerned.

Gas emissions and magmatic activity have been recorded, Peru This Week reports, but officials note the activity does not necessarily pose an immediate danger of eruption.

Officials warned people living nearby to refrain from building property too close to the volcano and to be prepared for evacuations, Wired reports.

According to the Smithsonian Institution's Global Volcanism Program, El Misti is Peru's most well-known volcano and hasn't had a major eruption since the 15th century.
