Stromboli (Eolian Islands, Italy): Lava flow activity continues. However, the recent surge in lava effusion seems to have considerably lost strength compared to yesterday.

Bárdarbunga (Iceland): Intense earthquake activity continues, but there is no signs of magma reaching the surface, i.e. a new eruption of the volcano yet.
So far, 164 quakes of magnitudes 1.2-2.8 have been detected today and tremor remains elevated.

Sakurajima (Kyushu, Japan): Since about a week ago, the frequency of explosions from the volcano has drastically increased and is now again almost similar to its intense phases of last year.
On 13 August alone, a record number of 9 explosions were registered. Ash plumes have been rising to 5-10,000 ft (1.5-3 km) altitude.
Reventador (Ecuador): Mild activity consisting of occasional small explosions, characterized as "moderate" by IGEPN, continues at the volcano. Most of the time, the volcano is hidden in clouds and this activity is inferred from seismic signals.
Tungurahua (Ecuador): The volcano's activity remains moderate with frequent small to medium sized strombolian- to vulcanian-type explosions.
This ongoing type of activity suggests that the volcano in a phase of having a relatively open conduit allowing magma to rise to the crater with no major obstacles. Incandescent ejecta are visible at night.
Some stronger explosions cause shock waves that let windows and roofs of houses in nearby areas vibrate. Ash fall has occurred many areas around the volcano including the sectors of Píllate, Bilbao, Mocha, Quero and Tisaleo.

Kilauea (Hawai'i): The June 27 flow remains active on Kilaueas East Rift Zone, and has advanced further into the forest over the past week. The flow front is 8.5km (5.3mi) NE of the vent on Puʻu ʻŌʻō. The flow's continued brisk advance rate is likely related, in part, to its continued confinement by local topography. In this USGS photo, the narrow flow front was within one of the many linear depressions (grabens) on the East Rift Zone. ... [more]

Stromboli (Eolian Islands, Italy): The lava flow continues to be well alimented with little variation visible. It forms an active stream on most of the Sciara, but its flow front during the past days only occasionally reached the sea, and rather accumulated to thicken the lava delta at the NE base of the Sciara. ...
