The Canary Islands El Hierro Has Raise Up Two Inches In Four Days

Thanks for the find, Cookiepuss! 

This isn't the super scary History Channel La Palma-causes-mega-tsunami island, but any island blown up and dropped into the ocean is going to cause a few ripples.  From ABC dot es.  Note the translation of the first two paragraphs would have benefitted greatly from the word "bulge."  Whole post:

The pressure of the magma detected in El Hierro has caused in the past four days on the island deformation of four to five inches vertically and three to four horizontal, as reported by the Security Directorate of the Canary Islands. (There's a translation issue here.  Or a nuance issue in the headline.  "Has raised up at least" would make more sense.  But that's just my guess..)


 The energy released has reached 420,000 million joules, a fact which, together with the ground deformation evidence magmatic process acceleration on the Canary Island, where there is an inflation process is centered in the area which earthquakes occur.


The General Directorate of Security, who coordinates the Civil Protection Plan Risk Volcanic Islands, said that since the beginning were found in magmatic process, last Sunday, have occurred in El Hierro over 750 earthquakes.


In the Sea of ​​Calm


The earthquake with greater magnitude of 4.0 degrees on the Richter scale, occurred on Wednesday at 18.55 hours in the Sea of ​​Calm, 2 km from the coast and 20 kilometers deep.


The seismic activity began in the Sea of ​​the Gulf (north of El Hierro) and then move to the center of the island, coinciding with the point of intersection of the ridges, to subsequently migrate to the west.


From noon on June 25 the seismicity is concentrated in an area that includes the west and the dorsal side of the Julan, and from 1200 hours on June 27 the focus of the earthquake begins to migrate towards the Sea of ​​Calm .

Let's hope the magma flow slows and things return to normal.  If you live near or on any Atlantic coast head's up!  Maybe this is nothing.  Or maybe this is not nothing.  At the least you should know so you can decide.

Time-bomb? Residents too afraid to sleep, ‘It’s making sounds we never heard before’

Popocatepetl follow up, File Under:  Uh-Oh..  The Extinction Protocol.  Excerpts:

Residents at the foot of Mexico’s Popocatepetl volcano no longer sleep soundly since the towering mountain roared back into action over a week ago, spewing out a hail of rocks, steam and ash. “We close our eyes, but we don’t sleep much. In the past, there was only smoke but this time it’s stronger,” said Francisco Jimenez, who lives in the nearby town of Xalitzintla in central Mexico, 55km from Mexico City. The volcano, Mexico’s second highest peak at 5 452m, started rumbling and spurting high clouds of ash and steam on 13 April, provoking the authorities to raise the alert to level five on a seven-point scale. The alert extended a security cordon around the volcano but stopped short of starting evacuations of about 685 000 residents from nearby communities. Over the weekend, residents watched as Popocatepetl, which means “smoking mountain” in the indigenous Nahuatl language, lived up to its name, spouting glowing rocks and shaking the ground beneath their feet.
And:
Popocatepetl is an explosive volcano that can suddenly erupt at tremendous force, thrusting out rocks and ashes at large distances. That kind of volcano can be more dangerous than those releasing only flowing lava. Residents say they are used to the permanent threat of the volcano but many say the new activity makes them nervous again. “We’ve been watching out for many nights, waiting to see what happens,” said Gabino Santibanez, mayor of San Pedro Benito Juarez, a small town only 9km from the glowing crater. Locals said that most frightening was the unusual rumbling coming from the volcano, which many compared to an aircraft turbine. “We’ve never heard a noise like it,” said Maximiliano Grajales. About 4.5 million people live on the outskirts of the volcano, which lies at the crossroads of the states of Puebla, Morelos and Mexico.

This Week's Volcano To Watch? Mexico City's Popocatapetl

Mexico City on alert as Popocatepetl volcano spews rock and ash  The Telegraph/UK.  Excerpts:

Eruptions from the Popocatepetl volcano began to grow larger a week ago as columns of ash began pouring from more than 60 openings in the 17,886 foot high cone.



On Friday a low pitched roar and rolling towers of ash and steam were spewed out as some of the pressure built up inside the magma chamber escaped.


Glowing rock fragments have also been sighted more than 3,000 feet down the slopes of the volcano.


Mexico's National Disaster Prevention Centre have now raised the volcano alert level to "yellow stage three" – the third highest level.

Tens of thousands of people live in the farming villages on the volcano's flanks while roughly 25 million people live within a 60 mile radius.


It is feared the airborne ash could cause havoc with Mexico City's busy airport and a large eruption of Popo, as it is commonly known, could see ash falling on Mexico City itself, around 50 miles away. 43 miles southeast, actually.

25 million people within 60 miles.  That's quite a lot of people to evacuate safely and efficiently, provided Popo really pops.  Yes, there have been many false alarms, and right now there's still no reason to expect the worst.  Still, this seems to be the year where everything breaks loose.  When it comes to Everyday Life and Earth Events, past context doesn't really apply anymore.

Meanwhile, worried countenances cast wary glances southeast, many breathing silent prayers, hoping the monster calms down, one more time..  Popocatepetl continues belching smoke, and its intermittent rumbling comforts no one.

This Bad Boy's Name Is "Hekla."

'Gateway to Hell': Airports brace themselves for ANOTHER Icelandic volcanic eruption putting summer holidays at risk  The Daily Mail UK via Rense.  Excerpts:

Scientists are closely monitoring unusual underground activity that could signal a massive explosion at a volcano dubbed the 'Gateway to Hell.'

The Heckla volcano in southern Iceland is capable of producing four times the debris of the country's last ash-producing blast that caused flights to be cancelled across northern Britain in May.
..
'No eruption has started in Hekla volcano. But it might start without any warning.' said Icelandic volcano expert Jon Frimann.
..
If Heckla blows, the amount of disruption it causes will depend on it size and the speed and direction of the wind.  (Obviously, experts expect this to be a substantial eruption..)

Both of Iceland's latest eruptions provided warning signs several hours before, but Hekla is known for having a very short fuse.

'Hekla never gives you much of a warning,' said Mr Einarsson, In 2000, it began rumbling an hour and a half before the outbreak of magma, which was actually an unusually long warning. In 1970 we only got 25 minutes notice,' he added.

Sweet.  The potential or active catastrophes continue to pile on, don't they?  In honor of Hekla resurgence, here's some B-52's.  Fuck it; let's dance..
