We have gone a
long time since we have had a really major eruption. This one appears big enough and it is still
early days. Thus it could build into
something really large vas we have experienced.
I suspect that
we are seriously overdue for a big messy eruption somewhere. Really messy is something that cuts the global
temperature by a degree. Howeve4r we
have had only a couple of such during modern times and knocking us back a
degree in a world that is most of a degree at present above average is easily
handled.
It is when we
are most of a degree below average that it hurts which describes the little ice
age.
Significant
Eruption Started at Indonesia’s Kelut

I don’t have many details, but news out of Indonesia
appears to be that a significant eruption (see above) has started at Kelut
(Kelud). News (mainly in Indonesia) suggests ash falling
upwards of 15-40 km from the volcano, some of it gravel-sized. The latest
monitoring data (see translation below) noted an eruption at 23:29 (local time)
and that the volcanologist have left their posts due to the eruption (also note
the comment on the far right bottom of the table). The BNPB has recommended
that all people living within 10 km of the volcano be evacuated. The Indonesian government has set up 78 evacuation shelters
around Kelud and only a few hours ago, the alert status had been raised to its highest level.

UPDATE 3:00 PM EST: I’ve added a composite image of
JMA weather satellite images (see above) that show how the plume grew between
1700 and 1900 UTC (2 hours). Seems like the eruption is on a similar scale to
the 1990 explosive event (hat tip to Alain Bernard for
pointing me to this data). The current
advisory from the Darwin VAAC has ash to FL450 (13 km / 45,000 feet).

UPDATE 2:30 PM EST: The Jakarta Post is reporting an ash plume from the
eruption of ~10 km / 32,000 feet with ash falling upwards of 50 km from the
volcano. Thousands of people are fleeing the area to evacuation centers, but over 200,000 people live within the 10 km evacuation
zone. I was also tweeted an
image of what is supposedly volcanic tephra from the eruption, supposedly 70 km from the volcano, but hard to confirm I’ve
confirmed its from 15-20 km out, not 70 km. I’ve also added another image of
what might be the opening moments of one of the eruptions today, also taken by
@hilmi_dzi (see above).

I’ll try to update with more information as it
arrives.
