An interesting article in The Jakarta Globe:

http://www.thejakartaglobe.com/indonesia/21-volcanoes-across-country-ready-to-erupt/399206

Asserts there are about 21 Indonesian volcanoes getting ready to rumble.

We’ve seen a load of quakes in Indonesia lately and it’s pretty clear the crust there is moving and flexing. For example, we’ve had 3 postings like this one for a 7+ quake in just a few months:

Here is a link to tthe news story about the prior Sinabung eruption:

So what’s in the present Indonesia Globe article? “Little Things” like:

Bandung. Twenty-one volcanoes across Indonesia could erupt at any time, leading to natural disasters, officials have warned.

An official from the Volcanology and Geological Disaster Mitigation Agency (PVMBG) told the Jakarta Globe on Friday that the alert for 18 volcanoes had been raised from Level 1, or “normal,” to Level 2, or “beware.”

Well, ingnoring for a while that ANY volcano with a history of erupting in the last couple of thousand years can “erupt at any time”, that’s still something to note.

But Wait, There’s More:

“We downgraded Sinabung from Level 4 to Level 3 on September 23,” Hendrasto said. “However, we still urge the public to remain alert for any danger.”

So it’s not blowing right now, but is still fuming…

The two other volcanoes on Level 3 alert are Mount Karangetang on Siau Island in North Sulawesi and Mount Ibu on Halmahera Island in North Maluku. Karangetang is considered the most active volcano in the archipelago, with 41 major eruptions since 1675. Its last eruption, on Aug. 6, is believed to have killed four people.

Ibu, meanwhile, has experienced ongoing eruptions since April 5, 2008, feeding a lava flow down one side of the mountain.

The 18 volcanoes on Level 2 alert include Papandayan in West Java, Slamet in Yogyakarta, Merapi in Central Java and Semeru and Bromo in East Java.
[…]
Other volcanoes on Level 2 alert include Talang in West Sumatra, Kaba in Bengkulu, Kerinci in Jambi and Anak Krakatau in the Sunda Strait, between Sumatra and Java.

Anak Krakatau is the remnant of Krakatau, whose violent eruption in August 1883 killed an estimated 40,000 people and was heard up to 5,000 kilometers away.

The eruption caused tsunamis as far away as South Africa, and resulted in global temperatures dropping by more than 1 degree Celsius.

Well. That could be a cold day in… New York…

Kerinci, at 3,800 meters, is the highest peak in Sumatra and the highest volcano in the country. It is a popular destination with hikers and wildlife enthusiasts because it lies inside the Bukit Barisan National Park.

In the east of the country, the Level 2 volcanoes are Batur in Bali, Sangeang Api and Rinjani in West Nusa Tenggara, Egon and Rokatenda in East Nusa Tenggara, Soputan and Lokon in North Sulawesi, and Dukono and Gamalama in North Maluku.

Frankly, just reading the list takes time and effort. That’s quite a list.
