Regent landslide in Sierra Leone: the causes of the disaster

The Landslide Blog | 22 August, 2017
The latest tally of losses from the Regent landslide in Sierra Leone has been released by the coroner.  To date 499 bodies have been recovered, with about 600 people still reported missing.  As expected, this is now the worst landslide of the calendar year to date.

Just Barely Through the Fog Banks: The Eclipse from Ground Zero, the Oregon Coast

Geotripper | 21 August, 2017
Yeah, I was really taking a chance, choosing to stay on the Oregon Coast for the 2017 eclipse. The reason? The fog. And there was a lot of it. To make the long story short, it never really lifted, but we could still see most of the sights through the clouds. I didn't get to see much of the corona, but there were lots of Solar prominences to compensate. It was an awesome experience in the end, but my nails are bitten down to the nubs!

Asteroid 2017 QP1 passes the Earth.

Sciency Thoughts | 21 August, 2017
Asteroid 2017 QP1 passed by the Earth at a distance of  62 640 km (0.17 times the average distance between the Earth and the Moon, or 0.04% of the average distance between the Earth and the Sun), slightly before 9.25 pm GMT on Monday 14 August 2017. There was no danger of the asteroid hitting us, though had it done so it would have presented only a minor threat. 2017 QP1 has an estimated equivalent diameter of 26-82 m (i.e. it is estimated that a spherical object with the same volume would be 26-82 m in diameter), and an object towards the upper end of this range would be expected to explode in an airburst (an explosion caused by superheating from friction with the Earth's atmosphere, which is greater than that caused by simply falling, due to the orbital momentum of the asteroid) in the atmosphere about a kilometre above the ground, with an explosive force about 600 times as large as that of the Hiroshima bomb; not large enough to cause long-lasting global problems, but fairly devastating for anyone directly underneath.

Imaggeo on Mondays: A total eclipse of the Moon

EGU Geolog | 21 August, 2017
Today, all eyes are turned to the sky; at least in North America, where the region will be treated to an eclipse of the sun. The online hype is hard to miss and its hardly surprising, opportunities to see the moon completely cover the Sun, where you are, are rare*. According to NASA, the same spot on Earth only gets to see a solar eclipse for a few minutes about every 375 years!

Well water in use

Oakland Geology | 21 August, 2017
Once upon a time, we used to produce a lot of our water from local wells, but for the last century we've retired them as the aquifers were drawn down or polluted. So I'm always surprised and intrigued to see wells still at work. This is on Willams Street in San Leandro.

Hoodoo 2017: Vancouver to Stewart BC

Our trip to Hoodoo Mtn volcano in 2017 was a long, complex but beautiful and interesting journey! Two members of the expedition (Will K and myself) flew in to Vancouver BC to load up on field gear for the trip. We were worried about the drive up, because BC is having a horrendous fire year and those blazes have closed several of the roads that cross center BC. The trip started perfectly though, with a gorgeous view of Mt. Baker volcano, in northern Washington State, which is clearly visible driving out of the Vancouver area on Hwy 1.

Hoodoo Expedition 2017

From 2 August to 11 August I revisited Hoodoo Mountain volcano, located along the lower Iskut River, in the Coast Mountains of British Columbia, Canada. This year was the 25th anniversary of my first visit to the volcano as part of my PhD research, in the summer of 1993. I have been to Hoodoo in the summers of 1993 (UBC), 1994 (UBC), 1996 (UBC), 1997 (UBC), 2004 (DC), 2015 (DC) and 2017 (DC), and it is one of the most spectacular places on Earth. Glaciers abound north of the Iskut River, and Hoodoo Mountain volcano stands out as an incredible, ice-capped mountain in the midst of the more jagged Coast Mountains (see pictures below). The shape of Hoodoo Mountain has been greatly influenced by the surrounding glaciers. Many of its eruptions have been beneath ice sheets, which have forced the lavas to form steep cliffs (some over 600 ft/200 m high) as they met the surrounding ice and got stuck. At least one period of the volcano's history involved large explosive eruptions, which formed deposits almost all the way around the mountain. The explosions produced during this period of eruption may have been as large as the 1980 eruption of Mt. St. Helens, although that is hard to verify for sure. But the deposits produced by the eruptions are over 100 m thick in some places around the volcano. Later eruptions probably happened under a thick ice cap to produce lava domes and spines, which are now encased in their own broken fragments (called volcanic breccia/tuff-breccia). The most recent eruptions produced lava flows that are likely only a few thousand years ago, but some of which are also older and partly filled the valleys to the east and west of the volcano. These valley-filling lavas either formed when the glaciers were absent from the valleys, or they may have melted the valley glaciers, because now as the surrounding glaciers are retreating (Hoodoo Glacier to the west, Twin Glacier to the east), these lavas are being uncovered by the ice.

Ostrom in the City: Design Principles for the Urban Commons

The Nature of Cities | 20 August, 2017
Elinor Ostrom's groundbreaking research established that it is possible to collaboratively manage common pool resources, or commons, for economic and environmental sustainability. She identified the conditions or principles which increase the likelihood of long-term, collective governance of shared resources. Although these principles have been widely studied and applied to a range of common pool resources, ... Continue reading Ostrom in the City: Design Principles for the Urban Commons '

Petaurista leucogenys: How the Japanese Giant Flying Squirrel selects its food.

Sciency Thoughts | 20 August, 2017
Many arboreal (tree dwelling) Mammals are reliant on leaves as a food for at least part of the year, and some feed exclusively on such fodder. However leaves leaves are difficult food, as, unlike fruits or nectar, these are parts of the plant which the plant does not want eaten, and many plants put considerable effort into making their leaves as unpalatable as possible, minimising the amounts of nutrients stored in the leaves, defending them physically with tough fibres or spines, and packing them with toxins such as phenols or tannins. Leaf-eating Mammals avoid these defences by carefully selecting both which leaves and which parts of the leaves they consume, and choosing different food sources and feeding methods at different times of the year.
