17-Year Cicadas About to Emerge in Eastern U.S.

Eerie sounds like those out of a science fiction film are about to ring ears across the eastern United States.

Every 17 years at this time, like clockwork, Brood II cicadas crawl out of the ground from North Carolina to New England.

The bugs live underground for nearly two decades, feeding off fluids that gather near the roots of plants.

They will eventually emerge by the billions when the temperature reaches 64 degrees Fahrenheit.

The Brood II, red-eyed cicada is smaller than the larger common cicada, which has green eyes and comes out every year.

They last emerged in 1996 and will fill the air with high-pitched buzzes that can be so loud they disrupt outdoor events.

But their periodic emergence and return to the ground help aerate the soil, and they return nutrients to the earth when they die. They also provide food for birds and other animals.

The 1.5-inch-long insects do not sting or bite. They spend their brief two-week lives above ground climbing trees, shedding their crunchy skins and reproducing.



Roundup of Global Volcanic Activity:

Stromboli (Eolian Islands, Italy): Activity remains elevated. Lava continues to overspill from the lips of the NE crater, showing that the magma column stands high inside the conduit. Frequent strombolian explosions are reaching heights of 2-300 m and the tremor signal is strong again today.

Etna (Sicily, Italy): A new paroxysm, the 10th such eruption in 2013, occurred today at Etna’s New SE crater, after a several days-long phase of increasingly strong strombolian explosions. It culminated with lava flows and lava fountains and a tall ash plume. Lava flows were erupted from the “saddle” area between the two Southeast Crater cones, toward the south and then southeast, from the summit vent of the New Southeast Crater itself toward southeast, and from vents on the northeast side of the cone.


Colima (Western Mexico): The new lava dome continues to grow inside the crater that had formed during the eruptions in January and has by now been completely filled by the new lava. The dome overspills the old crater rims to the southerns and western sides and produces glowing avalanches as well as small ash explosions several times per hour. A recent field report describes the dome as a blocky mass of lava, that is slightly darker than the rest of the volcano, composed of blocks of many meters in size. Part of the dome continues as a thick tongue of viscous lava stretching about 100 m down on the upper western flank. The balance between the rate of alimentation of the flow and the loss of mass during avalanches will determine how long this lava flow will reach.

Copahue (Chile/Argentina): A pilot reported the emission of steam, gas and minor amounts of volcanic ash from the volcano today (VAAC Buenos Aires). SERNAGEOMIN has not reported unusual activity and maintains alert level yellow.


Roundup of Global Volcanic Activity:

Stromboli (Eolian Islands, Italy): Yesterday evening’s lava flow has once again been very short-lived. Activity (effusion rate) sharply dropped late in the evening and today, only very small amounts of lava are still overspilling from the NE crater rim. Tremor and rockfall signals are much weaker as well. A strong increase of activity occurred this afternoon. A relatively large, sustained lava flow has started to erupt from the breached NE cone and descend the Sciara del Fuoco. The process is accompanied by ongoing strong strombolian eruptions, mainly from the same NE vent, and strong continuous tremor.

Etna (Sicily, Italy): This time, Etna is taking it really slowly to build up to the presumed next lava fountaining phase from the New SE crater (paroxysm). Tremor keeps rising, and strombolian explosions slowly increase from the summit vent of the cone. Strombolian activity at the New SE crater is intensifying and volcanic tremor is now steeply rising. The 10th paroxysm seems to be about to start.

El Hierro (Canary Islands, Spain): A relatively strong earthquake of magnitude 4.1 occurred at 5:26 GMT this afternoon, west of the island at 19 km depth. So far, it has been an isolated event.

Tolbachik (Kamchatka): The eruption continues with little changes. Strong seismicity of the volcano, although slowly declining, is being registered and accompanies ongoing effusion of lava flows and strong degassing from the southern fissure. No changes in seismic-visual activity have been reported for the other volcanoes currently active in Kamchata (Kizimen, Sheveluch, Bezymianny: actively growing lava domes associated with occasional avalanches and explosions, Karymski: occasional strombolian-vulcanian explosions, Gorely: strong degassing/hydrothermal activity).

Lascar (Northern Chile, Bolivia and Argentina): Chilean volcanologists were able to make make a helicopter overfly the day before yesterday and could not find evidence of recent lava in the summit crater. However, as the likely source of the recently observed incandescence, very hot gas emissions were observed. The airborne temperature measurements gave maximum values of 600° C for the gasses, and SERNAGEOMIN thinks that the presence of magma at shallow depth is causing it. The alert level remains at yellow.

Space Events

Massive Solar Eruption Could Cause Magnetic Storm Here On Earth

Early Thursday morning, solar observers watched as a dark spot on the sun erupted with an enormous flash of light, causing the biggest solar flare of 2013.

Solar flares themselves don’t last long, but this one was powerful enough to cause a bubble of solar material called a CME (coronal mass ejection) to come bursting off the sun.

Up to billions of tons of that solar material is now hurtling through space at the mind-bending speed of more than 600 miles per second, and it is heading directly toward Earth.

The CME will slow down a bit as it approaches our planet, and scientists expect it will reach the Earth’s atmosphere late Friday night or early Saturday, but computer models can be off by up to seven hours either way, said NASA scientist Alex Young.

While a mass of solar material zooming toward Earth sounds kind of frightening, there’s not much to worry about. CMEs can occasionally affect the electronic systems of satellites or the power grid here on the ground, but our atmosphere will protect us from any harmful radiation associated with the initial flare or the CME.

Roundup of Global Volcanic Activity:

Etna (Sicily, Italy): Strombolian explosions and relatively strong ash emissions from the New SE crater have continued throughout yesterday and the night, and seem to be gradually becoming more intense. However, this current behavior of Etna is a quite different from the usual more or less short build-up of activity the cone showed preceding the recent paroxysms. The tremor is slowly increasing.

El Hierro (Canary Islands, Spain): Earthquake activity has remained low, but there are still a few smaller quakes scattered under the island. This could be related to residual stress release caused by the relatively strong deformation the western part of the island experienced during the recent swarm.

Sakurajima (Kyushu, Japan): Since 4 April, no ash plumes / explosions have been reported from the volcano by Tokyo VAAC. This marks one of the longest intervals of relative quiet, i.e. absence of small to moderate volcanian explosions, in a long time. However, this does not exclude that minor explosive activity could be occurring.

Bagana (Bougainville Island, Papua New Guinea): More explosions have occurred. Ash emissions reached 7,000 ft (2.1 km) altitude, VAAC Darwin reported.

Manam (Papua New Guinea): An explosive eruption produced an ash plume rising to 7,000 ft (2.1 km) earlier today. The plume was observed on satellite data extending 40 nautical miles to the west (VAAC Darwin).

White Island (New Zealand): The strong volcanic tremor observed during the past days has dropped yesterday, but seems to be rising again today. GNS scientists reported that changes in water chemistry seen in recent samples from the White Island crater pool suggest that deep heat input into the volcano’s plumbing system has diminished or ended. If this is right and the trend continues, White Island should return to a more stable state in the near future.

Douglas (United States, Alaska Peninsula): A series of earthquakes up to magnitude 2.6 has occurred in the past 24 hours beneath the eastern flank of the volcano at depths around 20 km.

Colima (Western Mexico): Eruptive activity continues with frequent small explosions, rockfalls, and sometimes larger pyroclastic flows.

Popocatépetl (Central Mexico): Activity has increased yesterday to about 3 emissions per hour and occasional small explosions creating plumes rising up to 500 m. Glow at the summit indicates continuing lava dome growth.

Pacaya (Guatemala): Strombolian activity continues gradually to increase, and tephra is being thrown to about 25 m above the crater rim. Inside the Mackenney crater, a small lava lake has formed at the vent at a depth of 40 m, INSIVUMEH reports.

Fuego (Guatemala): Activity has remained relatively low with only smaller strombolian explosions. At night, glowing bombs can be seen ejected to about 100 m above the crater.

Poas (Costa Rica): The seismic signal suggests increased tremor and signals of possible hydrothermal explosions. An elevated SO2 concentration above the area suggests a higher level of degassing activity.

Nevado del Ruiz (Colombia): The Manizales volcano observatory published a special bulletin because of increased activity from Ruiz. Starting at 02:18 (local time) this morning, continuous volcanic tremor has been recorded. This is similar to signals recorded between 8 and 21 March 2013, although this new episode of tremor is of lower energy level than in March. Very often, such seismicity is associated with emissions of gas and / or ash. Volcano webcams showed a steam/gas column rising 1600 m above the volcano and drifting NW, and possibly containing some ash in it.

Spring Storm Batters USA

A large spring storm delivering heavy snow, strong wind and rain has caused travel problems from Wyoming to Chicago, closing large stretches of highways and delaying hundreds of flights.

Strong wind gusts caused 21 train cars to derail on Tuesday in eastern Nebraska, west of North Bend. No injuries were reported.

In Denver, about 16.51cm of snow fell at the airport, but the weather prompted nearly 500 flight cancellations and deicing planes delayed departures. Flights going to Chicago’s O’Hare International Airport, meanwhile, were being delayed an average of nearly four hours because of dense fog.

Many areas of Wyoming and western Nebraska received more than a foot of snow. In western Nebraska, road crews reported 8- to 9-foot drifts.
