Welcome to another Friday Update.
I will start with the easiest of the reports regions to write about. Europe, North America and Africa are continuing their quiet period with no reports of any activity from these regions.
This week saw a strong eruption from Zhupansovsky on the 12th of February, with Volcano Discovery reporting a plume sent up to 34,000 feet.

Not to be out done, Karymsky continues to throw ash into the sky with virtually daily reports of plumes the largest I spotted was up to 20,000 feet
And Finally on the Kamcatcha Peninsula, we have Sheveluch which threw a plume into the sky up to 15,000 feet on the 12th of February.
Moving to Indonesia, Dukono continues to produce mild to moderate ash emmisions, according to Volcano Discovery and a Google translate of news.okezone.com says “Dukono in North Halmahera, North Maluku, thin volcanic ash this morning. Volcanic ash reached an altitude of 1,500 meters and then move toward the north and northeast”
Sinabung keeps producing its now familiar pattern of ash plumes and pyroclastic flows.
Over inside the Tengger Caldera, the Darwin VAAC reports that Bromo is continuing to emit ash plumes up to 10,000 feet.
Semeru had a large pyroclastic flow on the 14th reaching up to 4.5km from the volcano and emitting a plume to 26,000 feet, causing the Darwin VAAC to upgrade its aviation warnings to RED, according to Volcano Discovery
Volcano Discovery also report on Ambrym “Wellington VAAC reported an ash plumes from the volcano this morning. Based on satellite observations, an ash cloud rose to 9,000 ft (2,7 km) altitude and drifted east.”
In Japan, Sakurajima continues to produce small explosive eruptions with the Sakurajima Eruptions Twitter feed reporting that volcano has its “15th (eruption) of the year” on the 17th.
Mexico’s Colima and Popocatepetl volcanoes continue as they have over the last few weeks, small explosions throwing plumes into the sky virtually every day.
In Nicaragua, Momotombo has had a number of explosive events over the past week, prompting René Goad to ask on our Facebook Page “Is it me or has the crater on Momotombo got larger?”
To which Alex Bogár posted this image taken a few days earlier and he also said “A small part collapsed too from the other rim, that’s why the pdc was so brownish colored”

In Guatemala, Washington VAAC reports that Santa Maria is continuing to produce plumes up to 15,000 feet with activity reported on most of the days of last week.
Only a couple of reports from South America with the Washington VAAC and the Buenos Aires VAAC reporting activity at Reventador and Sabancaya respectivley. Both reports state that plume was visible on webcam on the 15th for Reventador and the 13th and 15th for Sabancanya, but at the time of writing I was unable to find images from the dates in question.
At Copahue, the Buenos Aires reports a continuos emission of gases and steam and the occasional burst of volcanic ash.
This concludes my round up of the activity of the last weeks activity, did I miss anything??
