A slight increase of activity can be noted at Popocatépetl volcano in Mexico. The frequency of explosions has increased to more than 1 per hour, i.e. doubled when compared to last week.
The more energetic explosions produced small ash plumes rising up to 1 km. Episodes of volcanic tremor occurred as well, CENAPRED writes.
The new seismic swarm at El Hierro continues with hundreds of small quakes per day concentrated at about 20 km depth in the south-central part of the island near El Pinar. Pulses of tremor and a slight inflation are visible as well, but for now, it seems that magma is not moving much.
San Cristobal volcano had a small explosion yesterday at 8:17 am local time. Recent measurements showed an increase of SO2 emissions to 2,490 tons per day, i.e. almost double than before. Also, seismic tremor increased in the evening of 15 Sep.
Fuego volcano, Guatemala: Activity remains at normal levels with sporadic weak to moderate explosions with ash rising 400-800 meters and some rumbling sounds. The lava flow to the Taniluya canyon has apparently decreased a lot, as INSIVUMEH reported it to be only 50 m long yesterday.
Santiaguito volcano continues to have occasional explosions ejecting ash columns to 500 meters height, which spread west and northwest over the region of the villages of El Rosario and San Marcos, Palajunoj. There is constant activity in the 4 active lava flows, generating avalanches of blocks deposited within the river banks Nima Nima I and II.
Most other volcanoes in Central and Southern America have not shown any significantly unusual behavior.
Batu Tara had its daily explosion to send ash to about 7,000 ft altitude, VAAC Darwin reports.
A strong SO2 plume was visible from Manam volcano (PNG) today, suggesting that there is heightened activity or an eruption.
Sakurajima volcano seems to be having a break from its relatively strong phase over the past days. There was only one probably weak explosion reported during the past 24 hours.

News are dominated by the strong eruption of Fuego volcano, which has produced impressive and dangerous pyroclastic flows, 2-4 km tall ash columns reaching 24,000 ft (7.2 km) altitude, forced evacuation of 33,000 people yesterday. Today, explosive activity has decreased and the eruption changed to a more effusive style. Several lava flows are active on the southern flanks, threatening to cut local roads. ... [more]
