Roundup of Global Volcanic Activity – New Activity for the Week 2 June – 8 June 2021

Gareloi – United States : AVO reported that a minor increase in seismicity was first detected at Gareloi on 19 May. Beginning on 27 May the rate and size of small volcanic earthquakes increased and was sustained at that level. On 8 June AVO raised the Aviation Color Code to Yellow and the Volcano Alert Level to Advisory based on seismicity rising above baseline levels. Sulfur dioxide emissions had been identified in satellite images the past week, though they were consistent with measurements recorded in previous years. No other changes were evident in satellite or webcam views.

Semisopochnoi – Aleutian Islands (USA) : AVO reported that low-level unrest at Semisopochnoi continued during 2-8 June with seismicity occasionally above background levels. Steaming from Mount Cerberus was sometimes observed by field crews. Slightly elevated surface temperatures were identified in a few satellite infrared images during 4-7 June. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.


Wildfires – Arizona, USA

A half-dozen wildfires were burning close to 140,000 acres across Arizona Tuesday and growing, as heat, wind, and drought conditions complicated firefighting efforts, officials said.

The largest of the blazes, the Telegraph Fire near Superior, grew by 11,000 acres between Monday and Tuesday morning to more than 71,000 acres and led to additional evacuation orders in the region. More than 1,400 firefighters were fighting it and the 66,000-acre Mescal Fire near San Carlos by Tuesday afternoon.

Wildfires – Utah, USA

The Carbon County Bear Fire which is believed to have been sparked by lightning, has grown to 5,300 acres and shut down a highway (U.S. Route 6) with 0% containment; while the East Canyon Fire, which started when a piece of heavy machinery, a track hoe, hit a rock, grew to 835 acres, is now 45% contained, according to Utah Fire Info.
