Volcano Watch 2015-2021

Swarm E off Izu Peninsula a few days ago,
this spot has quite a few swarms, I did some pages of back in the 1980's, they don't seem to produce a heck of a lot of energy, but they sure do pound out the numbers
E off Izu Peninsula category
the one this week is the first one
also involved seismically is the area "Near Izu-Oshima Island", and this island has a history of volcanic eruption, in 1986

Mt. Sakurajima July 26 ,2016

One of my favorite blogs, VolcanoCafe, posted an article on VEI7 eruptions and the likelihood of one in the future along with likely candidates.

They discuss the characteristics that make for a VEI7 eruption (just below supervolcano) like Tambora, what the potential impacts on society would be depending on where it happened (inhabited or not) although we would all feel it. Tambora caused the year without summer. Think about what kind of impact something like that would have on the modern world ...

Then they discuss where such a candidate might be found and what its characteristics might be if you were looking for a culprit today.

Also, the commentary below the article contains more discussion of the topic for those who are really interested.

I thought I would leave this here, since this is the thread for watching suspicious volcanos.

Interesting. There was no seismic activity before during or after this eruption except this 2 hours after the event

ashfall page

While I was on JMA I found this page, hadn't seen it before
www.data.jma.go.jp...
very old info though.
I see Hakone DID erupt (with ash) in June last year when those swarms of micro earthquakes were going on, at the time it was hard to get any info of what was actually happening there.

Heads Up “Bardarbunga” restless…

Katla Volcano in Iceland Knocking????

Specialist remark
This night at 01:41 started an earthquake swarm within the Katla caldera. Two earthquakes were over M4. The largest earthquake occurred at 01:47:02 M4.5 and another one 20 seconds later, M4.6. The largest earthquakes were felt in the area. About 20 aftershocks have been recorded. No tremor has been seen.

Time to get the web cams going just in case!

VolcanoCafe is taking this Katla activity seriously, and they normally dismiss a lot of Katla talk as alarmist.

Scroll down to the bottom of the normal Pluto article which was posted prior to the Katla burbles to get the skinny about what may be happening there, including a good overview of Katla's eruptive past.

In short, the sudden shift in behavior around Katla seems to indicate that an eruption could be days to years away. Years if the current spate of activity dies back down, days if it continues and intensifies. Only time will tell.

Katla update//:
Glacial water is flowing into Múlakvísl river, south of Mýrdalsjökull. Increased conductivity has been measured in the river and gas measurements in the area show high concentrations of sulfur dioxide and hydrogen sulfide. People are advised not to travel near the river, due to gas pollution. It is not uncommon for glacial water to flow into Múlakvísl, causing increased conductivity and gas pollution.

According to local reports, the level of the Bláfjallakvísl glacial river is unusually high. Bláfjallakvísl originates from the northern side of Mýrdalsjökull and people are advised to show caution when crossing the river.

Party in Iceland Katla was knocking now Bardarbunga wants in…

3.2 & 3.4 mag in last 4 hours

I don't take any notice of Bardarbunga. It's been playing with me for years.
When there was the fissure eruption in 2014 Bardarbunga was knocking out mag 5+ almost daily for weeks.

I've deciced it just gets jealous when people talk about other volcanoes and it makes some noise.

I was reading yesterday that glacial run off water from Katla (on past experiences of big eruptions) could mean a serious eruption in a period of 48-72 hours from when the run off appeared. That would probably make it tomorrow? Guess we will see!

the ice cap on katla holded previous eruptions from surface....
now the cap is melting douwn last years an very large and explosive eruption can occure....
by braking up the ice cap....a reply to: Flavian

My geologic interests include the stratovolcanoes of the Pacific Northwest. IRIS released a terrific new video titled Volcano seismicity at long-dormant stratovolcanoes this week.

Give it a watch. It describes the different types of earthquakes we see, and the different settings that prompt them: VT, or high frequency volcano-tectonic quakes, LF, low-frequency quakes, and hybrid types, along with examples of their signatures.

katla burbing good now....

Minor Ash eruption at WHite Island ,NZ
Volcanic Alert Level: 3
Volcanic Activity: Minor volcanic eruption.
Most Likely Hazards: Eruption hazards near vent. Note: ash, lava flow, and lahar (mudflow) hazards may impact areas distant from the volcano.
