Tuesday Sep 24, 2013
Etna (Sicily, Italy): Weak strombolian activity and ash emissions continue from the New SE crater. Tremor amplitude continues to rise very slowly.
Batu Tara (Sunda Islands, Indonesia): Eruptions that produce relatively large ash plumes spotted on satellite imagery, and typically rising to 7-8,000 ft (2.1-2.4 km) altitude, have been occurring daily over the past days.
Sinabung (Sumatra, Indonesia): No more eruptions have taken place during the past days.Authorities allowed about 6,000 of the more than 10,000 reported evacuees to return to their homes.
Dukono (Halmahera): Activity (strombolian to vulcanian explosions from the crater) is currently at relatively high levels. An ash plume rose to 10,000 ft (3 km) altitude yesterday, and a weak SO2 plume can be detected on satellite data.
Lokon-Empung (North Sulawesi, Indonesia): No more explosions have occurred and degassing also has been much reduced recently. While the latest eruptive phase seems to be thus over, it is only a matter of time when the next one will occur.
Veniaminof (Alaska Peninsula, USA): The Alaska Volcano Observatory recently lowered the alert status from Orange/Watch to Yellow/Advisory. Although some weak tremor continues to be recorded under the caldera, no more eruptive activity seems to have taken place during the past weeks. The lava flows and the new cinder cone that was built inside the caldera are now cooling.
Popocatépetl (Central Mexico): No significant changes in activity have occurred. The number of small emissions has sunken to less than one per hour average. The largest during the past 24 hours occurred this morning producing an ash plume rising 1.5 km above the crater.
Fuego volcano (Guatemala): new lava flow

Explosive activity in turn has weakened and consisted of strombolian eruptions with ash plumes of 2-400 m height and incandescent material being ejected to about 100 m above the crater.
