The eruption at Kelud in Indonesia on February 14, 2014, with volcanic lightning being generated in the ash plume. Image: @hilmi_dzi / Twitter, used by permission. 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.

Klemetti.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).

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).
