Mount Dukono - North Molucas, Indonesia
Video made by Aris Yanto - His description :it's not so nice video, but better than nothing. Use Mi5 mobile phone and can take lighting from the Volcano. No Zoom, No Editing.
Volcano Dukono, is impresive eruption with plume sometimes about more than 700 m from the Crater.

Erta Ale volcano, Ethiopia (Philippa)
The aerial shot (below) of Erta Ale volcano in Ethiopia, which was taken by Joel Santos, was the overall winning image in the 2016 Travel Photographer of the Year awards. This basaltic shield volcano is believed to be one of the longest continuously erupting volcanoes in the world, and is characterised by lava lake activity with occasional overflows. Joel's image is currently on display in Hull, North East England, as part of the City of Culture celebrations. (via @BBC and Travel Photographer of the Year)

Maly Semyachik volcano, Kamchatka, Russia (Philippa)
The image (below) taken by @Bromotengger (Roberto C. Lopez) shows the crater lake within stratovolcano Maly Semyachik in Kamchatka, far-eastern Russia. The pale, milky-blue colour of the highly acidic lake is caused by the interaction of the volcanic gases with rainwater.

Taal volcano, The Philippines (Philippa)
Fieldwork photos via @INVOLCAN from the crater lake within Taal volcano in the Philippines. Here they are sampling the levels of the volcanic gases permeating through the lake waters to the surface. An increase of carbon dioxide (CO2) levels in particular would indicate either lake overturn (where gases from the bottom of the lake reach a critical level and suddenly rise to the surface as vapour bubbles) and/or renewed activity of the volcano.

Before and after the eruption (watch the similarities in sea color with the El Hierro eruption). If watched carefully one can see that the island like volcano did burst open at the northern end.

Reventador volcano, Ecuador (Philippa)
Images (below) posted by (Ecuadorian Civil Defense agency) ECU911 of Reventador volcano (left-hand image) and Cayambe. Ongoing ash emissions have been observed at Reventador via the webcam and satellite imagery.

Popocatepetl, Mexico (Philippa)

Below are webcam images via @SkyAlertMx and one of the seismograms from (monitoring agency) CENAPRED showing several of the recent eruptions at Popocatepetl volcano. CENAPRED reported that in the previous 24 hours there had been 23 small, explosive eruptions with emissions of steam, volcanic gas, and ash, and 79 effusive eruptions. Seismometers monitoring the volcano had also registered 20 minutes of low amplitude harmonic tremor, which is indicative of a more gas-driven, continuous eruption.

Etna volcano, Sicily
Archive images, such as the one below of Etna volcano in 1886, provide useful information about the previous eruptive behaviours of volcanoes so that we may better understand their potential future eruptions.

Bogoslof volcano, Alaska, USA (Philippa)
Since the images below (from NASA) were taken, an eruption on 16 May 2017 caused a breach of the north shore of the crater lake, and tephra deposits have extended the northeast shoreline by 300m.

This picture especially for our readers without a twitter account, this fascinating picture reminding us somewhat at the "almost surfacing" eruption of the El Hierro volcano.

How far can volcanic ash travel? (Philippa)
Willem van der Bilt and his research group at the University of Bergen, Norway, analyzed volcanic ash found within core samples of sediments from a lake in Svalbard, Northern Norway, and matched the chemical signatures of the ash to eruptions from around 7000 years ago in Kamchatka, far eastern Russia:

Eruptions continue at Sakurajima volcano, with the latest one confirmed at 02:27 UTC today (19 May 2017). The image posted (below) on Twitter by @WeatherRUS was taken on 17 May 2017, and is typical of the majority of eruptions from this volcano, which are small and ash-rich.
