Location of yesterday's earthquake under Momotombo volcano, Nicaragua
: Small earthquakes (mostly below magnitude 2) continue to occur frequently (10-20 per day), mostly under the central part of the island. Right now, this activity seems to be picking up, but it is too early to see if this evolves into another swarm.
Manam (Papua New Guinea)
: Explosions occurred this morning, producing ash plumes rising to 8,000 ft (2.4 km) altitude, VAAC Darwin reported.
Ijen (East Java, Indonesia)
: CVGHM reported that during 1 July-25 August diffuse white plumes rose 100-150 m above Ijen's crater, the lake water was light green, and seismicity decreased.

: VAAC Darwin reported an ash plume from the volcano at 8,000 ft (2.4 km) altitude yesterday morning. This might have originated from a larger than usual explosion.
The rarely visited volcano is one of Indonesia's almost permanently active volcanoes and often has strombolian to vulcanian activity.
: A large SO2 plume is drifting NW from the volcano, where at least two lava lakes in the Benbow and Marum craters remain active.
Veniaminof (Alaska Peninsula, USA)
: The eruption at the intracaldera cone of Veniaminof Volcano continues. The seismicity over the past 24 hours has been characterized by discreet episodic bursts of tremor, likely associated with lava effusion and minor ash emission.
Satellite images of the volcano over the past 24 hours have shown prominent thermal signals at the intracaldera cone, although views of the volcano have been infrequent due to cloud cover. (AVO daily update)
Popocatépetl (Central Mexico)
: Activity remains low with few (less than 1 per hour) weak emissions of steam and gas. Abundant SO2 output and glow at the summit indicate continuing lava extrusion.
Santa María / Santiaguito (Guatemala)
: INSIVUMEH reports strong rockfall activity from the steep-sided lava flows, suggesting that several of them are being alimented at the moment. Strong degassing produces a steam column rising up to about 1 km above the dome.
: Weak strombolian activity and the effusion of lava flows continues. The activity can be seen from the capital and the coast.
: The lava flows were no longer active yesterday morning. Activity consisted in weak to moderate strombolian explosions with incandescent material projected to up to 150 m above the crater, and ash plumes of a few 100 m height.
: A swarm of quakes including a shallow magnitude 3.8 felt earthquake occurred yesterday morning (16:38 GMT) at 3.5 km depth under the NW flank of the volcano. There are no reports of other unusual activity at the volcano.

Glowing blocks from the lava flow often detach from the front and roll down the steep slope of the volcano. No significant ash emissions have occurred so far. ... [more]

Sakurajima (Kyushu, Japan)
: On 21 August, the volcano had at least 8 (!) vulcanian-type explosions with ash plumes rising up to 15,000 ft (4,5 km) altitude that often drifted over the bay and Kagoshima city, causing ash fall there. Some of the explosions can be seen on the following time-lapse video. The volcano has been in an elevated state of activity during the past weeks. A significant hot spot is visible on MODIS data, suggesting that magma levels are high in the crater and the presence of significant amounts of still hot fresh deposits on the flanks. ... [more]
Thursday, Aug 22, 2013
