Vagabonding on Dangerous Ground: Our Tour of the Greatest National Park I Never Once Set Foot In.

Geotripper | 29 August, 2015
The western slope of the Cascades Range is green. Very green. There are trees, shrubs, mosses, grasses, just about every kind photosynthesizing plant there is. This is due of course to the mountains themselves. They provide a barrier to incoming Pacific storms, causing the moist masses of air to rise and condense, with copious amounts of rain and snow falling to the ground. We were still in the realm of the rainforest.

Scouring the Arctic for Traces of Fukushima and Ejections from Cosmic Impacts

In pursuit of resilience, it helps to be rich

Inkstain (John Fleck) | 29 August, 2015
"Resilience", as defined by these folks, is a useful framework for understanding drought and water management. The goal is a system that can withstand shock and retain its basic structure and function. For example by that metric, as Charles Fishman has pointed out, California during the current drought has demonstrated resilience.

Magnitude 1.8 Earthquake in Derbyshire, England.

Sciency Thoughts | 29 August, 2015
The British Geological Survey recorded a Magnitude 1.8 Earthquake at a depth of 1 km about 1 km to the east of the town of Chapel-en-le-Frith in the Peak District in Derbyshire, England slightly before 1.30 pm British Summertime (slightly before 12.30 pm GMT) on Wednesday 26 August 2015. There are no reports of any injuries associated with this event, though it may have been felt locally.

Tropical Storm Erika kills at least 25 in the Caribbean.

Sciency Thoughts | 29 August, 2015
At least 36 people are known to have died and over 50 more are missing after Tropical Storm Erika swept across the islands of Dominica, Puerto Rico and Hispaniola this week. On Thursday 27 August the storm swept across the island of Dominica, bringing 38 cm of rain within 24 hours and causing widespread flooding and a number of landslides. Landslides are a common problem after severe weather events, as excess pore water pressure can overcome cohesion in soil and sediments, allowing them to flow like liquids. Approximately 90% of all landslides are caused by heavy rainfall. Twenty people have been confirmed dead on the island, and at least 31 more are known to be missing, with the death toll likely to rise as contact is made with remote parts of the mountainous country, where much of the transport infrastructure has been knocked out.

Too Much Smoke — And Pelicans!

Looking for Detachment | 29 August, 2015
It's a little hard to tell how smoky it is from this picture, until you realize that Lassen Peak, the central feature of the Lassen Volcanic Center and Lassen Volcanic National Park, should be easily visible just to the left of the distant part of the highway. Here's what this same view looks like on Google Street View (or see the next-to-last photo of this post).

Cryptosporidium discovery at water treatment plant leaves around 300 000 without drinkable water in Lancashire, England.

Sciency Thoughts | 29 August, 2015
Around 300 000 homes were left without drinkable water after the parasitic microorganism Cryptosporidium was discovered at the United Utilities operated Franklaw Water Treatment Plant near Preston in Lancashire, northwest England, on Thursday 6 August 2015. The parasite, which causes stomach cramps and diarrhea and which can cause severe and persistent infections in small children and people with immunological disorders, is notoriously hard to remove by the use of disinfectants and is best eradicated from water supplies with exposure to ultraviolet radiation. For this reason around 300 000 customers in the Blackpool, Chorley, Fylde, Preston, South Ribble and Wyre areas were advised to boil all water prior to use for consumption or cleaning from 7 August onwards. On Thursday 27 August United Utilities lifted the boil water on about 80 000 homes in the Preston, Blackpool and Chorley areas, and the company hopes to restore normal water supplies to all of its customers within a week.

Erika Dissipates

Tropical Storm Erika charged into the teeth of Hispaniola's high mountains on Friday night, and emerged from the encounter shattered, without a closed circulation, and is no longer a tropical storm. Measurements on Saturday morning from an Air Force hurricane hunter aircraft failed to find any tropical storm-force winds associated with Erika, and the plane did not find any westerly winds, showing the the storm had degenerated to a tropical wave.
