Space Events

Severe Solar Storm

A severe solar storm slammed Earth on Monday afternoon, increasing the chances of fluctuations in the power grid and GPS. It also pushes shimmering polar auroras to places where more people can possibly see them.

Federal forecasters said the Northern Lights may be able to be seen Tuesday night as far south as Iowa or Pennsylvania.

The National Oceanic and Atmospheric Administration said a potent blast of magnetic plasma shot out of the sun on Sunday, travelling faster than usual, hitting Earth with the biggest solar storm since September 2005. The storm could last a day or longer.

Wildfires

Wildfires – Alaska, USA

Forty-seven new wildfires were sparked around Alaska on Sunday, pushing the solstice weekend total to 152.

Interior Alaska received a large portion of Sunday’s new fires — leading to burned structures, evacuations, a thick haze and air-quality advisories. An estimated 25 fires are active within 100 miles of Fairbanks.

Roughly eight miles southwest of the town of Anderson, the Rex Complex Fire has burned six houses and two minor structures and led to the evacuation of 25 residents. Rex Complex is comprised of two lightning-caused fires — the 5,000-acre Kobe Fire and 1,000-acre Fish Creek Fire.

The lightning-caused Nulato River Fire started about 5 p.m. Sunday, quickly grew to 75 acres and now threatens village infrastructure.

The roughly 600-acre Anaconda Creek Fire, about eight miles north of 24 Mile Chena Hot Springs Road, is being closely watched by the AICC. An air tanker is on the scene and structure protection is being performed.

The 10,000-acre Healy Lake Fire continues to burn near the Tanana River, but hasn’t changed much in the last few days, Capps said. The fire was discovered June 16.

Long Lake Fire — The 9,000-acre lightning-caused fire, two miles southeast of Northway, started Saturday afternoon. The fire currently is traveling away from the village. Moose Creek Fire was consumed by, and combined with, Long Lake Fire.

Chisana River Fire — Thirty miles south of the Long Lake Fire is the 33,805-acre Chisana River Fire, now the largest in the state. The fire has been burning 16 miles south of the Alaska Highway and 18 miles from the Canadian border since a June 9 lightning strike. Several cabins are threatened.

Tanana Slough Fire — 128 personnel are assigned to the 745-acre fire southeast of Fairbanks.

Nenana Ridge — Discovered on Saturday, the 500-acre fire in continuous black spruce has four personnel assigned to it.

Chitanana River Fire — The lightning-caused 800-acre fire is in monitor status. Iron Fire — Inside Denali National Park and Preserve, the fire encompasses 1,500 acres and had multiple starts or is spotting. The black spruce and tundra fire is in a monitor status.

Birch Creek — The fire northeast of Fairbanks spans 10,700 acres and is in monitor status.

Wildfires – Oregon, USA

Crews are trying to contain a wildfire burning south of the Succor Creek State Natural Area in Eastern Oregon. The Bureau of Land Management said Monday the 175-acre blaze was spotted the night before by an aircraft returning from a wildfire in Idaho. The cause of the wildfire has yet to be determined and there’s no estimate for when it might be contained.

Elsewhere, crews in southwest Oregon used a controlled burning operation to make progress on the nearly 5,000-acre Buckskin fire.

Wildfires, New Mexico, USA

Several fires are burning in the Gila National Forest, all of which were started by lightning strike this week. Three of the five are burning less than 400 acres, but officials did not say whether they were the three being used to achieve resource objectives.

The largest, the Pinon Fire, is burning 3,100 acres and is in Cox Canyon, east of Forest Road 94. It is moving in a northeasterly direction at a low to moderate pace.

The second-largest, the Moore Fire, is burning 1,700 acres on the Tom Moore Mesa in the Gila Wilderness.

Disease

Measles in Sudan

Confirmed cases of measles in Sudan this year already have quadrupled compared with the number for the entirety of last year, with the majority of those diagnosed with the disease being children under the age of 15. In light of the recent outbreak, Sudan on Monday launched the second part of a vaccination campaign against measles.

Anywhere between 500 and 600 cases of the infectious disease diagnosed yearly in the country is common, but the recent outbreak is the highest it has been in years, according to the United Nations. As of Monday, there were 2,511 cases of measles, and 38 people have died from the disease that is very rarely fatal because of vaccinations.

Volcanos

Roundup of Global Volcanic Activity

Cleveland (Aleutian Islands, Alaska): The Alaska Volcano Observatory detected that a new (so far minor) eruptive episode has started at the volcano recently: “Elevated surface temperatures have been detected in satellite images at the summit of Cleveland for the past week, and an image from June 14 shows very light ash cover on the volcano’s upper flanks. Thus the volcano has entered a renewed period of unrest and we are raising the Color Code to Yellow and the Alert Level to Advisory. The increase in temperature at the summit is consistent with renewed growth of the small lava dome within the summit crater. The possibility of sudden explosions has increased.” (AVO)

Kuchinoerabu-jima (Ryukyu Islands): Another eruption occurred from the Shindake crater shortly after noon on 18 June. It was not directly observed due to cloud cover and the island being evacuated, but sent out a clear explosion signal picked up on seismic stations. Japan maintains the highest alert level (5 out of 5) and the evacuated island inhabitants are currently not allowed to return to their homes.

Bulusan (Luzon Island, Philippines): Another eruption, moderately strong, occurred 14:55 last Friday, producing an ash column that rose 1.5 km. The eruption was not directly visible, only parts of the ash plume could be spotted, but could be heard as rumbing in Monbon village.

Manam (Papua New Guinea): An ash plume rising to estimated 10,000 ft and extending 35 km NW was reported yesterday by Darwin VAAC. Manam has been having intermittent periods with mostly minor eruptive activity for several years. A phase of increased explosive activity has been going on since late March this year.

Raung (East Java): A strong thermal signal visible on satellite data suggests that eruptive activity in the volcano’s summit crater has again picked up during the past two days. During late 2014 and early 2015, the volcano had been in strombolian activity and effused a lava flow inside its vast summit caldera. This activity had gradually decreased during the past months, but might now have resumed.

Wolf (Galápagos Islands, Ecuador): The eruption that started 4 weeks ago continues strongly, but from the location of the origin of the thermal signal it seems that since around 13 June, the eruption has been occurring from vents inside the vast summit caldera rather than from the fissure vents that opened on the upper ESE flank on 25 May. This could be because the dike (the fissure inside the edifice serving as pathway for the magma) that fed the original eruption has simply propagated into the caldera floor, or because an entirely new dike, hence a simultaneous second eruption has occurred. As judging from the thermal signal, the eruption continues with increased strength since mid June.

Pacaya (Guatemala): Mild strombolian activity has resumed in the main (Mackenney) crater of the volcano. INSIVUMEH reported intense degassing, small ash emissions, incandescence at night and volcanic tremor. The seismic activity of the volcano has been increasing during the past days accompanying the onset of the new eruptive phase. There is a possibility that it further increases and produces a more violent eruptive phase with lava fountaining and/or lava flow activity.

Fuego (Guatemala): Activity has been relatively intense. Strombolian-type explosions with abundant incandescent bombs up to 200 m and ash plumes rising 1000 m have been frequent. A lava flow of 200 m length is active in the direction of the Santa Teresa drainage (WSW side). Explosions generated strong rumblings and weak shock waves. In addition, locomotive-like degassing sounds lasting several minutes can often be heard.

Ubinas (Peru): A new phase of intermittent explosions and associated ash emissions from the volcano started Saturday evening (20 June). The new surge of activity has been accompanied by a rise of seismic activity since early June, characterized by earthquakes related to rock fracturing under the volcano and signals caused by internal fluid movements, both results of increased internal pressure. A weak thermal anomaly had also become visible on satellite data since mid June, as more heat is being transferred to the crater of the volcano. This announced the rising of a new magma batch that is now causing the currently still small eruptions.
