Major fire out of control at Libya's largest oil storage facility.

Sciency Thoughts | 28 July, 2014
A fire is burning out of control at a fuel storage facility in Tripoli, after a tank holding 6 million liters of oil was hit by a rocket during fighting between militia groups on Sunday 27 July 2014. The fire was initially brought under control by firefighters, but the were forced to withdraw when fighting resumed early on Monday 28 July, shortly after which a second oil tank was ignited by shrapnel. The fire is now described by the Libyan National Oil Company as 'out of control', provoking fears of a major explosion or environmental catastrophe. Local officials are recommending that residents evacuate the area within five kilometers of the facility, but with ongoing fighting in the area it is unclear whether many people will be able to comply.

Granites, Glaciers and the Ocean: a hike

Earth Science Society | 28 July, 2014
We hiked, the other day - a well-known coastal trail, but new to me. So much still to discover here and it's not like we haven't been trying. The trail is in Crystal Crescent Beach Provincial Park and takes the hiker all the way around the Pennant Point peninsula in about 4 hours.

Asteroid 2014 OP2 passes the Earth.

Sciency Thoughts | 28 July, 2014
Asteroid 2014 OP2 passed by the Earth at a distance of 199 700 km (0.52 times the average distance between the Earth and the Moon), at about 8.35 am GMT on Thursday 24 July 2014. There was no danger of the asteroid hitting us, though had it done so it would have presented no threat. 2014 MG6 has an estimated equivalent diameter of 3-9 m (i.e. it is estimated that a spherical object with the same volume would be 3-9 m in diameter), and an object of this size would be expected to break up in the atmosphere between 45 and 32 km above the ground, with only fragmentary material reaching the Earth's surface.

One more hummingbird picture

Inkstain (John Fleck) | 28 July, 2014
Sorry, can't resist posting one more hummingbird picture. The rufous, on the left, have just finally arrived at our house. They're usually earlier in the summer, and they're very aggressive, driving away the black-chins who have been here since late spring. Moments after this picture was snapped, the rufous drove the black-chin away:

Want to Really Communicate Your Science to the Public? Go on a Journey and They’ll Follow

Nicole Davi, a William Paterson University researcher who studies tree rings, cores a white oak tree in Hutcheson Memorial Forest in Somerset County, N.J., to learn about past droughts. These trees are some of the last remaining "old growth" in New Jersey and date back to the 1600s. Photo Credit: Lizette Gesuden.

A pilot’s life at 65,000 feet over Alaska

New book: Intraplate Earthquakes

Paleoseismicity | 28 July, 2014
Intraplate earthquakes are those that occur far away from plate boundaries in what is often also referred to as slowly deforming regions or stable continental regions (SCR). Seismicity there is comparably low and earthquake recurrence intervals can easily exceed thousands of years for individual faults. However, intraplate quakes do account for a significant number of earthquake fatalities and killed more people than those that happened at plate boundaries during the last 100 years (England & Jackson , 2011). A new book has been published a few days ago, dedicated to summarizing our knowledge of these seismic events.
