Apple has put out a recall for specific iPhone 5 units after realizing a flaw with the batteries. As described in the company’s notice, a few numbers of iPhone units were delivered with faulty batteries. This fault in battery compels the users to charge it more often than the normal ones. Apple will swamp these batteries without a cost.

The company has a sequence number which will help the customers to find out whether their device need a fresh battery or not. The iPhones who have faults in their  batteries were sold between September 2012 to January 2013. It is one of the earlier shipment, which happened soon after the release of these iPhones.

Apple puts some condition on this battery replacement procedure. It is that the company would not be able to change the batteries of a damaged phone such as cracked screen, etc. As far as other damages are concerned, Apple stated that it will change the batteries for free if damages are not that difficult to handle.

Customers have to contact their nearest Apple service center of retail stores for the substitution. Customers should back up all the data through iTunes or iCloud and switch off Find my phone.

The replacement program continued till the month of March 2015. The recall has started in some countries like China and U.S previous week.

Iceland on Friday issued red alert after lava fountains were found dancing along an extended volcanic fissure near the Bardarbunga volcano system on Sunday.

The small eruption prompted the authorities to raise the aviation warning to the highest level, signaling closure of the surrounding airspace.

Making an statement in this regard, the National Crisis Coordination Center said, “The Icelandic Met Office has raised the aviation color code over the eruption site to red and the Icelandic Air Traffic Control has closed down the air space from the earth up to 18,000 feet.”

On a five-color scale, red is considered to the maximum alert level. It suggests that an eruption is impending and have a risk of ash.

The authorities also confirmed that no sign of ash were found following the small eruption that could have potential to affect the air travel in Europe.

“No volcanic ash has been detected with the radar system at the moment. Seismic eruption tremor is low indicating effusive eruption without significant explosive activity,” the National Crisis Coordination Center said.

The meteorological agency of the country said that the authorities are doing close monitoring over the eruption in the Holuhraun lava field, which is located about five kilometers north of the Dyngjujoekull glacier which covers part of Bardarbunga system.

According to the Reykjavik’s Meteorological Office, a small eruption began in a lava field just after midnight local time. The experts said that an ash cloud is at highest risk during a sub-glacial eruption.

According to the met department, the fissure eruption on Sunday was more powerful than the one occurred on Friday. But the experts stressed that the condition is not worrisome as it is unlikely to result into the aviation chaos that occurred following the 2010 Eyjafjallajokull volcanic eruption.

In April 2010, an eruption at the Eyjafjallajokull volcano led to the cancellation of more than 100,000 flights due to the official closure of Europe’s air space, wreaking havoc on millions of travelers.

Yellow Stone national Park is currently in news as volcanic calderas & super volcano are located here. The caldera & the most of the park are located in the northwest corner of Wyoming. This region has already experienced 3 eruptions and those were around 2.1 million years, one at 3.1 million years & recent one was 64,000 years ago.

As per the studies & research though there will be super volcanic flare up , at least meter of ash would wrap Rocky mountain range & it can also touch cities on the both coasts of US it may hamper the air travel also  . According to the further research there has been seen relative consistence at yellow stone. Park officials don’t expect this eruption anytime in next 1,000 years and also park is well equipped with monitoring systems & there would be plenty of warning would be set weeks or even months before this eruption would take place.

United states Geological survey are in use of newly developed 3- dimensional modeling program called as Ash3D,  states that though there is a explosion in yellow states that fallout would be huge difference in the fall out then what was expected earlier. The eruption makes its own winds that can overcome the prevailing westerlies that normally dominate weather patterns in United States.

The chances of a volcanic eruption are very low in this given year for sure but still all required measures and frequently checks are being done by the US Geological survey & also continue studies are done on the thickness & distribution of ash deposits if yellow stone erupts

The distribution of ash has a different pattern than smaller eruptions creating an umbrella cloud that can push ash more than a thousand km upwind Yellowstone hasn’t erupted for 70,000 years, so it’s going to take some impressive earthquakes and ground uplift to get things started. And which will be definitely monitored before hand with all there equipments placed in the park .  In Case of emergency experts recommend keeping extra supplies on hand and creating a family emergency communication plan. Beyond that, there is no reason to specifically prepare for an eruptive event at Yellowstone, which remains very unlikely.
