Daily volcano update

Agung erupted Monday night at 20:02. It was an eruption measuring 25 mm in amplitude (small), but lasted for a relatively long 240 seconds.

Nikki McFarlane noticed a bright one minute light from the crater across the cloud cover and captured it just before the plume started (attached). Comparison of eruption data attached.

It looks like the internal pressure is not as high as before. (Note that the * 9-Dec occurred SIX eruptions in one period, range of data, the others are individual.)

Other overvalued events on the seismograph include a deep volcanic tremor yesterday morning at 10:44 am (amplitude 25 mm), and a distant earthquake at 0:26 am in the Bali Sea. It was a 4.1SR tremor about 60 km northeast of Lombok - earthquake trio, with the other two north of Bima (Sumbawa), and further north from Flores.

The normal recalibration of the seismograph appears at 22:31. There were 21 shocks sprinkled yesterday, more than we've seen in a while, but the maximum (small) amplitude was 4 mm - more than 25,000 shocks since September 2017. There is a lot of activity but not a lot of pressure.

240 evacuation stations reported 70,947 people registered in evacuation camps in all districts of Bali.

Darwin's VAAC reported ash last night, but as shown in FlightRadar24's image (and notes) from 7:30 am, but notes that "ash fell below levels visible on satellite imagery" but they can not see it.

The photo with a good layer of ash comes from Amlapura around 23:30 last night. The Rendang observation post reported that thin ashes fell last night before midnight (southwest wind), and people on Ubud, Giyanar, Canggu (photo of Canggu Batubolong scooter), Denpasar, Kerobokan reported light ashes on their bikes this morning. The winds are generally heading west-southwest this morning.
