For the Friday fold, Callan digs out images of Eagle Rock, Virginia, well aged in his digital archive for a decade!
Planet Labs have very kindly made available before and after imagery of the landslides triggered by the Jiuzhaigou earthquake in China on 8th August 2017

We’re finally ready to dust off the wheels and get back to driving towards Vera Rubin Ridge. Today was a pretty smooth day of planning, as we’re still getting back into the swing of things.

Sea level rise hot spots — bursts of accelerated sea rise that last three to five years — happen along the U.S. East Coast thanks to a one-two punch from naturally occurring climate variations, a new study shows.
A showcase of five new 3D digital models of awesome rock samples and outcrops, produced using Agisoft Photoscan.
Education standards and frameworks are moving away from memorizing scientific content and toward engaging students with the nature & practices of science. Primary literature can be powerful tool for teaching with emphasis on real science, and AAAS Science in the Classroom can help make this happen.
Curiosity’s Navcam will image for clouds (like the clouds in the above image from Sol 1758), scan for dust devils across the crater basin, and measure the LOS extinction of dust towards the crater rim.

Early indications suggest that M=7.0 Jiuzhaigou County earthquake in Sichuan Province yesterday should have generated significant landslide activity
Small ocean waves could play a bigger role in breaking up ice shelves than tsunamis or other large waves, a new study suggests. A new study examining vibrations in Antarctica’s Ross Ice Shelf finds small waves continuously impacting the ice shelf may create enough strain to extend existing cracks in the ice and potentially create new ones. An ocean wave of 1 centimeter (0.5 inches) in height can cause vibrations that repeatedly move the ice more than 20 centimeters (8 inches).
Various analyses have now been posted about the the tsunamigenic the Karrat Fjord landslide in Greenland, which killed four people
Oh, why not. The draft Special Climate Assesment Report is here. The NY Times published the leaked report and it’s not good news. I plan on reading the whole thing this weekend, but the Executive Summary at the top will give you the take home points. The short of it is that climate change is already having a significant impact on our weather in the U.S. Perhaps most notable is the increase …

Berastagi, a city in northern Sumatra, is a great place for volcanoes, because it has two active ones: Mount Sibayak and Mount Sinabung. Active takes on a different context here; to the locals, Sinabung is active, and dangerous, while Sibayak, which hasn’t erupted in living memory, is not.
Are you in Portland at ESA2017? So is (part of) Sharing Science!
How will future disasters affect countries in Eastern Europe and Central Asia? Researchers aiming to answer this question used projected changes in population and Gross Domestic Product (GDP) for 33 countries, along with climate, flood and earthquake risk models, to estimate how each country is affected by flooding and earthquakes now and in the future. In addition, the earthquake model was used to estimate fatalities and capital losses from a strong quake.

As Mars comes out from behind the Sun, scientists are easing back into operations planning for the Curiosity rover.

It’s Friday and that means “fold time” here at Mountain Beltway. Today, we feature a trio of samples on display in the halls of the Department of Earth and Planetary Sciences at the University of New Mexico.
We just passed Trans-Alaska Pipeline mile 100, which means that distance remains on our summer hike from Valdez to Prudhoe Bay. My dog Cora and I started walking on April 30, which means we’re in our fifth month of sleeping outside.

A new study has identified the climate variation patterns which exert the most influence on atmospheric river activity along the West Coast. One of these patterns is the long-term increasing trend associated with Pacific Ocean warming likely due to human activity.
