Indonesia's Mount Agung volcano erupts for a second time in less than a week as seen from the coastal town of Amed, in Bali, Indonesia.
The Mount Agung volcano, on the Indonesian island of Bali, has erupted for a second time in less than a week, firing a column of ash 1,500 meters into the air.

The eruption emitted a bigger ash cloud than Tuesday's blast. It caused several airlines - including, KLM, Qantas, AirAsia, and Virgin - to cancel or rearrange flights in the region.

"Tourism in Bali is still safe, except in the danger (zone) around Mount Agung," Indonesia's Disaster Mitigation Agency (BNPB) said in a statement.

"There has not been an increase in seismic and volcanic activity after the (Tuesday) eruption until this afternoon," the statement read.

Great Sitkin volcano eruption in Alaska on November 19 2017
An increase in seismic activity and degassing prompted the Alaska Volcano Observatory (AVO) to raise the alert level of the volcano to yellow today:

"Recent observations of a robust steam plume and a period of gradually increasing seismicity over several months indicate that Great Sitkin Volcano has become restless and is exhibiting behavior that is above background levels. AVO is thus raising the aviation color code and volcano alert level to YELLOW/ADVISORY.

"Photographs of the volcano taken by local observers on Sunday, November 19 show a light-colored vapor plume rising about 300 m (1,000 ft) above the vent area and extending about 15-20 km (9 - 12 mi) to the south. Nothing unusual was observed in seismic or infrasound data around the time the photographs were taken and nothing noteworthy has been observed in satellite data since the emissions were observed.

Popocatepetl Volcano spews smoke and ash
A cloud of smoke, ash and steam rose to around 5,900 feet over Mexico's Popocatepetl volcano following November 23's eruption, the largest since 2013, El Universal reported.

Mexico's National Center for Prevention of Disasters (CENAPRED) warned residents in Central Mexico not to approach the volcano's crater and of the potential for volcanic ash to fall to the southeast of Popocatepetl.

Eruptions in 2013 from Popocatepetl, Mexico's most active volcano, caused airlines to temporarily cancel flights to and from Mexico City due to the threat from volcanic ash.

This post is a response to "Variation of the Solar Microwave Spectrum in the Last Half Century", Masumi Shimojo et al. Astrophysical Journal, Volume 848, Number 1.

The abstract states:
"... we found that the microwave spectra at the solar minima of Cycles 20-24 agree with each other. These results show that the average atmospheric structure above the upper chromosphere in the quiet-Sun has not varied for half a century, and suggest that the energy input for atmospheric heating from the sub-photosphere to the corona have not changed in the quiet-Sun despite significantly differing strengths of magnetic activity in the last five solar cycles."

Tens of thousands of people have fled their homes in Bali over the past months, fearing an inevitable Mount Agung volcanic eruption, which on Tuesday, finally spewed ash as high as 700 meters into the Indonesian sky.

The volcano on the Indonesian resort island erupted at 5:05pm Tuesday, the National Disaster Mitigation Agency (BNPB) announced, urging residents to "remain calm" and to stay away from areas within 7.5-kilometer radius of the volcano.

However, despite the high volcanic activity, flights in and out of Bali are continuing as usual. "Tourism in Bali is also still safe," the BNPB said while asking tourists to stay away from Mount Agung.

Volcanoes are erupting all over the place right now. Scientists have figured out why: A minute slowdown in the planet's rotation

Image
The Earth seems to have been smoking a lot recently. Volcanoes are erupting in Iceland, Hawaii, Indonesia, Ecuador and Mexico right now. Others, in the Philippines and Papua New Guinea, erupted recently but seem to have calmed down. Many of these have threatened homes and forced evacuations. But among their spectators, these eruptions raise this question: Is there such a thing as a season for volcanic eruptions?

While volcanoes may not have "seasons" as we know them, scientists have started to discern intriguing patterns in their activity.

Eruptions caused by a shortened day

The four seasons are caused by the Earth's axis of rotation tilting toward and away from the sun. But our planet undergoes another, less well-known change, which affects it in a more subtle way, perhaps even volcanically.

Due to factors like the gravitational pull of the sun and moon, the speed at which the Earth rotates constantly changes. Accordingly the length of a day actually varies from year to year. The difference is only in the order of milliseconds. But new research suggests that this seemingly small perturbation could bring about significant changes on our planet - or more accurately, within it.

Comment: Finally, some government-approved scientists have 1.) noticed the increase in volcanic activity, and 2.) connected it with a minute slowdown in planetary rotation.

It needs to be further explained, however, that the 'seasonal' changes to patterns of erupting volcanoes marry with 'seasonal' changes to patterns of other climatological, seismic and cosmic phenomena. There aren't just more volcanoes erupting now. There are more earthquakes now. There is more precipitation now. There is more snow now. There are stronger storms now. There is more methane outgassing now. There is more heat coming up from the oceans now. There are more meteor fireballs now. There are more comets in the solar system now. There are more cosmic rays reaching Earth now.

Etcetera, etcetera.

All of it is inter-related, which is why climatology alone cannot explain what is going on. Only a (truly) multi-disciplinary approach - one that is disinterested in biased assumptions that improve chances of receiving grants - can account for all the observation data.

SOTT.net has been saying for years that a slowdown in the planet's rotation can account for much of what has unfolded in terms of global planetary and climate chaos in the last decade or so. The question is: what is causing the planet's rotation to slow down? It cannot simply be "factors like the gravitational pull of the sun and moon" because the same thing is happening to other planets in the solar system!

The new caldera can be seen clearly on this image.
A new caldera, measuring a diameter of one kilometre has been formed in this last week in Öræfajökull glacier, a caldera spotted via satellite images of the glacier.

Iceland's volcanoes may be ready to blow

According to the Iceland Met Office this caldera shows increased activity in Öræfajökull which is located in Vatnajökull, Iceland's largest glacier.

A great sulphuric stench has emanated from the river Kvíá last week.

Increased seismic activity has occurred in the area in recent months, activity which has subsided in recent days. The volcano hasn't erupted since 1727. There are still no signs of an imminent eruption states an announcement from the Met Office. However, the safety code has been put up to yellow.

Footage of the moment the Popocatepetl volcano erupts, spewing a huge plume of ash into the air near Mexico City, has been posted online.

Popocatepetl, meaning 'smoking mountain' in Aztec, erupted three times in the space of 24 hours across Thursday and Friday. The ash, described as "moderate" and "light" by civil protection authorities, fell over the nearby towns of Tétela del Volcán and Ocuituco, according to El Sol de Cuautla.

The stratovolcano, which annexes both Popocatepetl and the dormant volcano Iztaccihuatl, has been emitting ash since the beginning of this month, with explosions detected at various times over the last 10 days, according to the Global Volcanism Program.

Shallow 5.0 magnitude earthquake recorded off Bali near active Mount Agung volcano

Earthquake strike near Mount Agung

Earthquake strike near Mount Agung
An earthquake measuring 5.0 magnitude on the richter scale was detected in Bali near Mount Agung on Thursday morning.

The quake's epicenter was in the sea, 11 kilometers east of Karangasem, at a depth of 10 kilometers at 5:54am local time, according to data from the Bali Meteorology, Climatology and Geophysics Agency (BMKG).

The earthquake did not trigger a tsunami warning.

The epicenter was about 12 to 13 kilometers from the summit of Mount Agung, Bali's rumbling volcano that is currently on level III "standby" the second highest alert level for an eruption. Agung has been on standby since Oct. 29 after previously being on level IV "danger" for five weeks.
