Thousands of dead tuna crabs wash ashore on Imperial Beach, California, USA

Thousands of tuna crab washed ashore near the pier in Imperial Beach Wednesday morning. 
 
Lifeguards first discovered the crabs during low tide. This marks the second year in a row the tuna crabs have washed ashore in such large numbers.
 
“Just like last year, in June we had a washing of tuna crabs and they think its correlated with El Nino,” said Imperial Beach Lifeguard Captain Robert Stabenow. “The warmer waters are pushing them up and when they hit the cold waters of San Diego, they die off.”
 
The majority of the crabs that washed ashore in Imperial Beach are dead, but some are still alive. Experts are advising that people do not eat the crabs because they may be covered in toxins.

Strong Eruption Of Volcano Affects Capital Of Costa Rica

Volcano Alert

The strong eruption by volcano Turrialba at the 01:19 local time affected a great part of the Costa Rican capital, which got up Thursday covered by a thin layer of ashes.
 
Television stations transmitted images of the exact moment of the explosion, with a column of smoke and ashes, gases and other materials.
 
The Turrialba is 3,340 meters high, the 2nd highest in Costa Rica after the Irazu volcano, with 3,432 meters, and the experts stated that after this eruption, which lasted 11 minutes, the volcano went back to its passive state.
 
Most of the affectations were located in the Central Valley, particularly San Jose, the capital, and the smell at sulfur was still present, just as ashes in the air.
 
Though the majority said that till now they have not presented any difficulty for this exhalation of the colossus, specialists recommend the asthmatic people and persons who suffer lung diseases to avoid to inhale the air impregnated with these gases.
 
Specialists of the Volcano and Seismological Observatory of Costa Rica talk about the perception of tremors of low intensity in the entrails of the Turrialba, that on Thursday, April 28th increased its eruptive activity.
 
This increase in its emanations forced the National Commission of Emergencies (CNE) to adopt a series of measures, as the suspension of classes and the extension of the yellow alert from two to five kilometres in the surroundings of the Turrialba.
 
For the experts, the eruption of this dawn is comparable with the ones reported in October, 2014 and March 2015, when the hill presented strong eruptions.
 
What calls the attention is that after the emanations of last days, the volcano diminished its emanations and the CNE decided to raise the adopted measures.
 
This way, the Department of Public Education announced that today the educational personnel and the student population of the schools of the region will take again the normal development of the school cycle.
 
Still it is not known if these educational centers resumed the classes, though the certain thing is that in this eruption the affected zone is different to the one that forced CNE to implement the above-mentioned measures.

Activity Picks Up A Bit At Stromboli Volcano In Eolian Islands, Italy

Activity at the western vent yesterday morning
Following a phase of very low activity during most of March-April (often with several hours between small explosions only), activity has picked up again and strombolian-type explosions, mainly from the western and eastern vents in the crater terrace, have been more regular. 
 
According to INGV’s monitoring data, activity of the volcano, internal (seismic) and external (explosions) is at low to moderate levels.

Ongoing Seismic Unrest At Bardarbunga Volcano In Iceland

Earthquakes under and near Bardarbunga volcano during the past week
Ever since the large Holuhraun fissure eruption (Aug 2014-Mar 2015), the volcano has remained restless. Over the past months, the volcano’s seismic activity has been showing a slow increase. 
 
The quakes have been concentrated at shallow depths under its central caldera, and the northeastern fissure system (in particular, near Herdubreid volcano). So far, the frequent earthquake swarms have been small and rarely contained quakes above magnitude 3; an eruption in a very near future seems unlikely for now. 
 
However, they indicate that the volcano’s storage system is probably recharging with new shallow magma intrusions; a new eruption of Bardarbunga in a not too distant future (months to years) would certainly not be a big surprise.

Alert Raised To Level 2 Due To Increased Degassing And Heat Output In Ruapehu Volcano New Zealand

Ruapehu volcano sat by (c) Google Earth View
The alert level of the volcano was raised by a notch from 1 to Level 2 (moderate to heightened unrest) last Wednesday, Geonet informed in a special note. 
 
This was triggered by recent measurements that showed an increase in the degassing from Mt Ruapehu’s Crater Lake, a rise in temperature from 25 to 45 deg C since mid April, and ongoing moderate levels of volcanic tremor (reflecting the degassing). 
 
The Aviation Color Code was also raised from Green to Yellow.
 
Whether or not the volcano is going to produce a new eruption in the near or medium future is still far from certain. According to the Geonet, the volcano’s current seismicity and increased heat flow are “not exceptional in terms of the last few years.” The current unrest could (but not necessarily must) be a precursor of new volcanic activity at Ruapehu in the medium-term future (weeks to months), but it could as well remain a peak in temporary elevated internal activity only, such as the volcano’s many regular heating cycles which typically do not escalate into eruptions.
