Roundup of Global Volcanic Activity:

El Hierro (Canary Islands, Spain): Earthquakes and tremor have continued through the day, and continued to migrate a bit to the NW off the NW tip of the island. So far, 62 quakes above magnitude 2 have been recorded today. In addition, the average depth of the latest earthquakes has become a bit shallower and is now around 13 km (compared to 17-20 km before). This suggests that magma is still moving and has risen a bit closer to the surface, and, thus, a possible eruption. A third, intense pulse of quakes and harmonic tremor started late last night and is going on at the moment. A magnitude 3.8 quake early today marks the so far largest event. The location of the latest quakes moved again a bit further to the west, and is now clustered at about 15-17 km depth beneath the western tip of the island.

Batu Tara (Sunda Islands, Indonesia): Activity remains elevated. Another explosion today produced an ash plume rising to 10,000 ft (3 km) altitude, VAAC Darwin reported.

Ambrym (Vanuatu): Elevated SO2 emissions remain elevated, suggesting that the lava lakes remain active.

Popocatépetl (Central Mexico): The volcano's activity has stayed rather calm and not changed much. Yesterday, the rate of emissions was down to less than 1 per hour, but seems to have increased a bit today, as the current seismic signal suggests.

Santa María / Santiaguito (Guatemala): Activity at the dome has decreased compared to last week. INSIVUMEH reported only weak explosions with ash rising 400 m, and few and small avalanches from the lava flows today.

Fuego (Guatemala): The volcano has been considerably calmer today, with only 5 mostly weak explosions detected, which produced ash plumes rising 400-800 m above the craters. The (mostly now cooling) lava flow erupted two days ago still produces frequent rock falls and small avalanches.

Telica (Nicaragua): The seismic swarm at the volcano continues, with many small tremors registered beneath the eastern sector of the volcano. There has not been any apparent surface activity reported (so far).

Nyiragongo (DRCongo): A strong SO2 plume is drifting westwards from Nyiragongo volcano, which contains the world's largest active lava lake.
