Its pretty bad Indonesia Semeru volcanic eruption kills 13; dozens injured

Actually if your TV programs shows the damage it would be better. The ashes from the fallout was just horrible. Here's a bit from one news article.
To be honest with you all, I hope Mt. Fuji doesn't start acting up. I know the govt. here has been in talks for the last 10 years to move much of the main govt. offices elsewhere in Japan, but so far no action taken.

In a barren landscape covered in ash, homes were almost completely submerged, and a truck had only the top of the driver's cab visible.

Semeru had started emitting hot clouds and lava flows near its rivers recently, and the country's volcanology center had warned people not to go near it since Wednesday, it said.

The amount of eruptions since September has been up to about forty four at one given time.

The one to worry about is Taal in the Philippines. It's massive and has been getting steadily more active for a while without letting off any steam in an eruptive way. It has been put on yellow alert several times with no result. It is big enough to rival Tambora if it really goes. Odds are it won't do that ... but ...

More immediately, it would absolutely devastate a wide swath in the local area with death and destruction.

and now I count forty one or more , site must of been updating...

this site says about forty eight since October

1350 worldwide active overall but not erupting.

Amazing, what 130-140 currently active volcanoes. Yikes. Time to move.

Taal erupted recently on January 12, 2020.

Not enough to release the pressure buildup. If anything what you're seeing are indications of the pressure being built up under the lake in those phreatic eruptions.

This part is something that I have hoped that I would never have to write, and I hope with all of my heart that I am wrong in this case.

The 234 square kilometre caldera of Bulkang Taal (Taal=Pure or True) would to most people not look like a volcano at all, instead it looks like a beautiful and peaceful lake with an island in the middle. If you look at the island you will find another lake, and that lake would definitely give things away since it is merrily boiling all the time.

Nobody who is reading this will have missed that Bulkang Taal, The True Volcano, have been active since 2020. The local authorities have at least twice raised the alert level to 3 on a 5-degree scale, and with good reasons.

There have been minor phreatic blasts in the lake as water have come into contact with fresh intruding magma, the gas flow has increased at times to levels where the capital of Manilla was inundated with hazardous vog, there have been widespread and substantial uplift and caldera extension.

And there have been numerous earthquake swarms, both of volcanic type earthquakes, and tectonic rock breaking types.

What is giving me reasons to be less than happy here is that the activity has been going on since March of 2019 and since then the activity and the data at hand has slowly increased in severity.

For a lack of better words, it has been like seeing a giant slowly wake up, put on the clothes, having coffee, and then going out in the garden starting to build up a mountain of gunpowder. The longer it is building up that metaphorical mountain of gunpowder, the worse it could be when the fuse is finally lit.

Long runups like this is generally not a good thing around volcanoes of this size and type. If it erupts fairly fast after onset the eruption will most often be manageable, but years of building to an eruption? Rarely a good sign.

Currently I would not be surprised if the eruption when it finally occurs will be in the range of the eruptions during the 18th century, or even as big as the 1754 eruption. As such they would be a disaster for the area in and around Bulkang Taal.

What could we expect from such an eruption? At least 1 meter of ash covering the downwind shores of Lake Taal and quite a bit of disruption to the economy of the Philippines.

A more unlikely scenario, but that is well within the capacity of Bulkang Taal, is a larger eruption. It is here prudent to remember that the entirety of the scenic lake has been created by a number of eruptions ranging from VEI-6 to VEI-7. The sad part is that the longer the runup-phase last, the greater the risk increases of something like this happening.

Currently the risk of something horrendous happening is perhaps 1 percent, but even that is an uncomfortable number indeed.

I do not like being restless volcano calderas like The Pure Volcano. Not at all.

I know this is a lengthy quote from the article, but the article itself is even longer since it covers five different volcanos and the part about the one in question is at the very bottom. That's the only reason I pulled this much of it to quote.

yes Taal is and has been a concern since just before the pandemic hit. and why at the beginning of the pandemic there was a critical shortage of masks, since pretty much all had been used to protect from all the ash in the air from it. and that ash reached right into the capital city of Manila. and breathing in that ash is deadly, acting like cement in the lungs. not only that, but the biggest freshwater lake, which of coarse supplies water for Manila is pretty much between Taal and Manila, so i would suspect ash contamination in that lake could be an issue.

i know they had the immediate danger area around Taal cleared back before the pandemic. but i believe at least those not on the island itself have been allowed to return. and since it is an island on a lake, any lava flow is not a huge danger. although projectiles from it and more ash, still would be to the surrounding populated area.
