Iceland Volcano Alert Lowered to Orange; Small Eruption Overnight Near Bardarbunga Originally Pushed the Alert Level to Red

A small fissure erupted near Iceland's Bardarbunga volcano on Friday, but no volcanic ash was detected by the radar system, officials in Iceland said Friday. Immediately after the eruption, they raised the aviation warning code to red as a precaution, but the alert level was lowered to orange by midday, after scientists could get a better handle on the situation.

The eruption took place at the Holuhraun lava field, north of Dyngjujoekull glacier, Iceland's Meteorological Office said. The event was described as being not highly explosive - and thus not producing much of the fine ash that can affect aircraft engines.

"If this eruption persists it could become a tourist attraction, as it will be relatively safe to approach, although the area is remote," said David Rothery, a professor of Planetary Geosciences at The Open University in Britain. "This event should not be seen as 'relieving the pressure' on Bardarbunga itself, nor is it a clear precursor sign of an impending Bardarbunga eruption."

New cracks and sinkholes were spotted Wednesday in the ice that encases Bardarbunga. That ratcheted up concern that an eruption was near.

Seismologists have been concerned about a possible eruption, particularly as earthquakes grow in size and frequency. Wednesday alone saw at least two tremors above magnitude 5 at the volcano.orange, the second highest.

In 2010, Iceland's Eyjafjallajokul volcano erupted and sparked a week of international aviation chaos, with thousands of flights canceled. Aviation officials closed Europe's air space for five days, fearing that volcanic ash could harm jet engines.

When a volcano sends ash thousands of feet into the air, it isn't visibility concerns that ground planes, Time.com reports. It's actually the chemicals in the ash that can damage a plane's delicate engines, while the ventilation holes can become clogged and stall the aircraft.

Huge 99L Generating 55 mph Winds, But Remains Disorganized

A huge and powerful tropical wave (Invest 99L) is generating winds of tropical storm force near the Virgin Islands, and could become a tropical storm at any time over the next two days as it heads west-northwest at 15 mph towards The Bahamas. If 99L develops a well-defined surface circulation, it will be called Tropical Storm Hermine.

Hottest Reliably Measured Air Temperatures on Earth: PART TWO

In my previous blog I discussed the various contenders for what might be the hottest reliably measured air temperatures on Earth. That blog focused on those that were most likely not reliable for various reasons. In this blog I will briefly list those that I believe to be the most reliably measured. This takes into account such factors as climatology (general and specific to the sites at time of observation), properly exposed instrumentation, and good correspondence with other temperature observations in the vicinity of the record-breaking site(s).

An extraordinary meteorological event; was one of its results a 1000-year flood?

The confluence of meteorological ingredients the first weekend in October 2015 resulted in an extraordinary weather event with severe impacts. Was one of them a 1000-year flood?

Why the Arrest of a Science-Loving 14-year-old Matters

By now, many of you have heard or read about the arrest of Ahmed Mohamed, a 14-year-old high school student from Irving, Texas. Ahmed was arrested because school officials called the police after he showed one of his teachers his homemade clock. Mistaken for a bomb, Ahmed was taken into custody, interrogated, shamed, suspended (still on suspension today, Wednesday), and reprimanded. All of this after it has been found that the "device" he brought to school was indeed, a homemade clock.
