Using Google Earth it is possible to track down the location of the Kyrgyzstan loess landslide. This is an area with many similar landslides, some of which have also displayed high levels of

Where on Google Earth (click on image to view).Lynn David met all three of the recent geo-challenges:"Obviously Nebraska.... cannot mistake that bend in the Platte River. #1 Looks like you're on the bluffs above the Niobrara River (one of my favorite rivers) just northeast of the sand hills area, which might make that the Ogallala. Though I keep thinking it shoud be something older in the Arikaree, Laramie or Chadron? #2 Looks to be the Scotts Bluff area which would make it the [...]
Where on Google Earth? (click on image to view)Here’s a special deal to celebrate the start of 2016 geo-tripping: three geo-challenges for the price of one! I visited all in a period of five days, traveling by car. Where was I?Ordered by increasing age of strata:#1 Darker brown is caused by seepage from the base of a super important aquifer.#2 Thousands of immigrants passed by—did anybody notice the white ash layers and curious wavy contact? #3 This rock is gray when fresh, [...]

Where on Google Earth are we?Some hints ... Arrows point to stream deposits from roughly 20 million years ago. Obsolete names date from the late 1800s.Stream deposits cap a ridge (inverted topography); Devils Smoke House and Gabriels Castle behind. Note spectacular unconformity. The trail on the ridge crest passes through stream deposits turned to rock and photogenically eroded. Layers of sand, pebbles, cobbles record changes from about 20 million years ago. [...]
It is likely that the Bento Rodriguez disaster was triggered by the collapse of the Fundao Dam. Google Earth reveals the history of the
My (very) rough interpretation of the Walker Lane on Google Earth.
As for the broad geology of the Palmetto Mountains area, what I knew back in the spring or early summer of 1976 was quite broad, and it probably wouldn't have filled up the trunk of my '72 Opel. The main thing I knew—besides that the region was known for its silver mining, and that the silver mines were presumably of the

My friend Barbara am Ende sent along this lovely image of a dike in Colorado: Here’s the site. You can see the dike in Google Earth. Dikes are fractures, filled with molten rock, which then cools and solidifies, sealing the crack shut. In this case, once it got uplifted to Earth’s surface and exposed, the dike rock is tougher (more resistant to weathering) that the older rock it cut across.
I've been writing periodic updates on Bhuvan and have been critical about some of its features before. Today I sing its praise.
Bhuvan is the Indian Space Research Organization's web mapping portal. It was launched with much hype in 2009, touted by the media as a Google Earth killer. That it hasn't turned out to be. Google Earth /Maps is still the most used application for browsing
Mono Lakes Eastern shore has been shaking lately. A lot. This has been going on for around a week now, as I have kept my eyes on it. Nobody is writing anything particularly useful about the goings-on there, so I thought it would be good to mention it.Screenshot of Mono Lake quake swarm from Google Earth with USGS Real-time quake overlay.The Eastern shore of Mono Lake is experiencing a couple of small shallow quake swarms, although some quakes have reached magnitude three or higher. This is [...]
The writer George Monbiot has linked the Harbury landslide with the removal of vegetation from the embankment that failed. This does not seem to be correct based on the images on Google Earth and from the
My student Josh B. found this beautiful map view of a plunging fold in the bed of the Shenandoah River, as viewed in Google Earth: Josh posted his results on Facebook, and then the other Josh (Joshua Villalobos of El Paso Community College) poked around the area and found some others downstream (north): Here’s a Google Maps link to the site. Check it out!
Geologists have developed clever ways to peer deep beneath the earth's surface and these tools are being utilized to get a clearer picture of the November 30 earthquake in Oak Creek Canyon. In addition, aftershocks have been pretty regular since the 10:57 PM main shock.Courtesy Google Earth with annotations by Jeri Young Ben-Horin at AZGSHere is a Google Image provided by colleagues that shows how the epicenters for the aftershocks have migrated northeast from the main shock epicenter. The main [...]
I joined a field trip to the Pinacate Volcanic Field in Northern Mexico this past weekend. It was a part of the Planetary Volcanology class taught by Amanda Clarke and David Williams. It was beautiful and very interesting. I had never been there, but just stared at it on google earth:Here are a few pictures:Crater EleganteThe Pinacates are in a biospheric reserve: http://elpinacate.conanp.gob.mx/. Crater Elegante: nice example of the phreatomagmatic features in great evidence. Nice bomb sag in [...]
A nice quake swarm is occurring just South of Lassen Volcanic Center in California, US. The largest quake so far in the series has been a 3.9, and at this time the swarm is ongoing. So far around 35 quakes have occurred in the area over magnitude 1. It is unclear at this time whether the quakes are tectonic or volcanic in nature, however the fact that most are quite shallow could indicate this is merely a tectonic or hydrothermal event. Time will tell.Quake swarm south of Lassen. Screenshot [...]
Where am I? what's all that weird orange rock?! maybe I was out too long.Plants and Rocks is back from vacation, with one more geo-challenge to share. But I had to wait until today to post it (hint).It was a land of strange and eerie rock creatures – hundreds of them!Those in the prime of life were spooky ...... but the old and dying evoked sympathy. Though made of rock, their lives are short.Where on Google Earth? Click on image to see hordes of rock [...]
Many of my students and colleagues and I just returned from the 2014 Southern California Earthquake Center meeting. It was really great: so much energy, so many old and new friends and colleagues. It is a very strong community with a world-leading emphasis on earthquake system science. I am on the Planning Committee and so was of course very engaged many aspects of the meeting. Here is a fun picture from the meeting:Back row: Kate Potter (ASU), Kendra Johnson (Colorado School of Mines), Ed [...]

After a few months of relative quiet at California's Long Valley Caldera, East of Mammoth Mountain volcano, activity has intensified with hundreds of small and shallow quakes at depths of around 4.7 miles. Many small tremors are occurring below the surface about 1.5 miles north of Yosemite Mammoth Airport. These are small quakes, and likely not able to be felt by anyone not at the epicenters. These quakes are interesting mostly due to the sheer numbers, not the magnitude.More than likely these [...]
