3,300 ft. Fissure in the Mexican Desert: No Locusts, But You Should Still 'Freak Out'

Last week video emerged of a giant fissure in the Northern Mexican desert, 3,300 feet long and up to 25 feet deep. Speculation centered at first around an earthquake, but the region is not known for seismic activity. I personally checked out the USGS earthquake data because the Buena Vista Copper mine (the fourth largest in the world by output) is only about 150 miles north of the enormous crack, and earlier this month they spilled 40,000 cubic meters of sulphuric acid into two rivers during the worst spill in Mexico's modern mining history. But I found no reports of tremors in the region and authorities were skeptical that this had anything to do with an earthquake.

Fast forward to yesterday (August 26, 2014), the Washington Post posted a story with this headline: "Why no one should freak out about the giant crack that opened in the Mexico desert." The Post reports:
The chair of the geology department at the University of Sonora, in the northern Mexican state where this “topographic accident” emerged, said that the fissure was likely caused by sucking out groundwater for irrigation to the point the surface collapsed.
“This is no cause for alarm,” Inocente Guadalupe Espinoza Maldonado said. “These are normal manifestations of the destabilization of the ground.” 
I'm sorry, no. These are not normal manifestations of natural activity, this is the result of human activity run amok. Just because Cthulhu isn't clambering out of the breach to wreak havoc on humankind DOES NOT MEAN we shouldn't be alarmed by the fact we've sucked so much water out of the ground that the surface of the earth is collapsing. 

Barely a month ago NASA's Jet Propulsion Laboratory warned of 'shocking' groundwater losses in the Colorado River basin, a major watershed to the north of Sonora with similar climate and landuse. Using gravitational data from the satellite-based Gravity Recovery and Climate Experiment (GRACE) instrument, scientists found "the basin lost nearly 53 million acre feet (65 cubic kilometers) of freshwater. That's almost double the volume of the nation's largest reservoir, Nevada's Lake Mead. More than three-quarters of the total -- about 41 million acre feet (50 cubic kilometers) -- was from groundwater."

The Post also reports that cotton used to be a major crop, but intrusion of saltwater from the Sea of Cortez caused some areas to become unusable for agriculture. However, there is still plenty of large-scale agriculture as evidenced by the Landsat image below.

However, around the green fields, there appear to many fields that are not being irrigated this season – seen as tan rectangles with a faint grid of roads in between parcels. The blue geometric shapes on the left appear to be salt-drying pans.  

Groundwater reserves can take centuries to recharge, so industrial-scale extraction of water for big agriculture in the middle of the desert cannot continue forever. In the US, water managers are facing an uphill battle to control water use in the Colorado River Basin and from the Ogallala Aquifer which stretches from Texas to South Dakota. Factor in that hydraulic fracturing is permanently removing water from the hydrological cycle in some of the most drought-stressed regions of the West, and you have a serious problem. 

To be clear, the southwestern US and western Mexico are not necessarily about to fall in on themselves all at once, but they are struggling to support large-scale agriculture, enormous demand for water from a revitalized onshore oil and gas industry, and a growing population. Maybe this chasm in the desert doesn't herald the coming of Judgement Day, but perhaps we should be 'freaking out' about our poor judgement.

SkyTruth Releases Dynamic Map of Global Flaring


SkyTruth is releasing a dynamic map of satellite data visualizing the wasteful practice of natural gas flaring around the world. The SkyTruth Global Flaring Visualization compiles nightly infrared data from NOAA's Suomi NPP satellite, and filters it to display gas flares associated with oil and gas production. The map is a direct result of a crowdfunded groundtruthing mission last year in North Dakota's Bakken Shale where flares light up the night sky.

Flaring from a Bakken shale wellpad just outside Williston, North Dakota, as seen by a camera aboard a high-altitude balloon launched by SkyTruth and Space for All in Sept. 2013.

“This new tool makes the scale and frequency of flaring more comprehensible and less abstract,” said Paul Woods, Chief Technology Officer at SkyTruth. “Hopefully, enabling everyone to see where, when, and how often operators are flaring will create public pressure on government and industry to reduce the waste of this hard-won natural resource,” Woods continued.

Also released today, SkyTruth's partners at Earthworks have produced a report on flaring in the Bakken and Texas' Eagle Ford Shale, finding that North Dakota drillers have reported burning $854 million in natural gas since 2010 and that neither state independently tracks how much gas has been lost forever through flaring. Earthworks also calculated that the 130 billion cubic feet of natural gas burned in the Bakken and Eagle Ford Shale has produced the equivalent of 1.5 million cars’ emissions of carbon dioxide – a greenhouse gas.


SkyTruth's flaring map puts these enormous numbers in perspective, and can enable regulators and citizen watchdogs to see if companies really are taking action to reduce the occurrence of flaring. Click below for more information and to see a full-screen version of the map.

SkyTruth is announcing a very special edition of our FrackFinder Ohio project, courtesy of our partners at FracTracker and Lighthawk. With FrackFinder Ohio: Wellpad Mapper - 2014, you can map drilling in Caroll, Columbiana, Harrison, and Jefferson counties using brand new aerial survey imagery flown by LightHawk pilots back in May.

So far, all our FrackFinder projects have used aerial photos from the USDA's National Agricultural Imagery Program (NAIP), but this gives you a chance to do some skytruthing with the freshest imagery around. Last year we had to wait about six months to get the latest high-resolution USDA imagery, and they only survey once every 2-3 years. This project is one of many exciting examples of how the costs of remote sensing technology are coming down; meaning we can do more frequent and better-quality skytruthing. 

In this phase of FrackFinder Ohio we are continuing our wellpad mapper project, so all we need you to do is indicate if there is visible drilling activity at the site we show you. Based on the data from the 2013 imagery you should see drilling infrastructure at nearly every site. Just click the link below, we'll show you a quick tutorial, and you'll be ready to start mapping fracking...



There are only about 140 sites for each person to review, so this project will go fast. Then come back to help us measure the total area impacted by drilling.

Satellite Detects Massive Spill at Canadian Gold Mine

SkyTruth – Shepherdstown, WV: On Monday, August 4, 2014, an approximately 580 acre tailings impoundment failed at a Canadian gold and copper mine near Likely, British Columbia. The breach at Imperial Metal's Mt. Polley mine dumped an estimated 1.3 billion gallons of toxic mine waste into the surrounding environment. On August 5, Landsat 8 acquired an image of the mine showing that grey sludge from the breached dam has entered Polley Lake, saturated the entire length of Hazeltine Creek, and entered Quesnel Lake over five miles downstream of the failed impoundment. 

The spill has prompted drinking water bans throughout the region, since the pond contains a slurry laden with arsenic, lead, mercury, selenium, and other toxic metals and compounds.

The president of Imperial Metals, Brian Kynoch, claims that the water in the tailings pond is "near drinking water quality" and expressed disbelief that the impoundment could fail so catastrophically, despite the fact that Canadian officials had issued multiple warnings to Imperial Metals for exceeding water quality standards for effluent and exceeding the permitted wastewater levels in the pond. 

Local citizens anticipating the arrival of a salmon run now fear the worst for the environment and tourism, especially as they begin to document dead fish in Quesnel Lake. 

Environmental groups across North America will be watching this story closely given the similarities to the proposed Pebble Mine in Alaska's Bristol Bay watershed, the world's most productive wild salmon fishery. Tailings ponds at Pebble mine would cover a surface area 13 times larger than the Mt. Polley impoundment and would have earthen dams taller than the Washington Monument

Mining in Wisconsin - Another Consequence of Fracking

How is mining related to fracking? 

Well, the process of hydraulic fracturing forces fluid into the rock at extremely high pressure.  This pries open natural pre-existing cracks (fractures) in the bedrock, and also causes new cracks (induced fractures) to form. This network of enhanced and induced fractures is what allows gas and oil to flow out of the rock and into the well. To keep these fractures from snapping shut when the fracking operation is completed and the pressure is eased, you need to prop them open with something.  That's why fracking fluid - a highly engineered fluid that is mostly water by volume, but can contain dozens of different chemicals - always includes a "proppant." The drilling industry has developed manufactured proppants, but often the proppant of choice is a clean, consistent, well-rounded, tough, fine-grained sand. A typical fracking operation in the Eagle Ford Shale in Texas, for example, can use 4 million pounds or more of sand. 

Where is all the sand coming from?  As you might expect, Texas is one place where sand-mining is booming.  But surprisingly , most of this sand comes from a place more famously associated with beer and brauts:  Wisconsin.  The rapid proliferation of sand-mining operations is getting a lot of attention there and raising concerns about public health and safety, property values, quality of life, and environmental impacts. 

Responding to these concerns, the Wisconsin Department of Natural Resources (DNR) just published an interactive map showing the locations of all the facilities, active and inactive, involved in the mining and processing of sand in that state.  Their map doesn't have imagery, so you can't actually "see" any of these mining operations.  But when we asked, the DNR promptly gave us the facilities data (updated as of May 1, 2014), so we could make our own map using Google Maps Engine:

Voila!  Here is our map of the Wisconsin frac-sand operations.  We decided to only include "active" facilities on this map.  Now you can explore and zoom in on any facility, and see the latest high-resolution imagery available through Google (July 2011 in the example shown above).

Burning Fuel Depot, Tripoli

A fuel storage site in Tripoli was apparently hit by rocket fire this morning and set ablaze.  Satellite imagery taken today from NASA's Terra satellite shows a long, black smoke plume originating at Libya's capital and extending many miles to the west-southwest.  The Libyan government is asking for international assistance to extinguish the massive blaze.  

See updates on our Facebook page.

SkyTruth Uses Satellites to Track – a Bicycle?!

[Update - July 28, 2014: Tony successfully completed the challenge and we have switched the map from a live view of his most recent location to a static overview of the whole journey.]

Shepherdstown, WV –  On Friday, July 25th, SkyTruth will turn our attention from aimless oil tankers and drilling sites in America's Heartland to an unlikely suspect - a bicycle. Technically we're more interested in the man riding the bicycle – Tony Long, Director of the Ending Illegal Fishing campaign at the Pew Charitable Trusts. 

Long, a former commander in Her Majesty's Royal Navy (UK), is taking part in the Action London-to-Paris ride, a 24 hour, ~240 mile challenge to raise money for children's medical research. Along the way Tony will be carrying a SPOT personal tracker provided by SkyTruth in order to demonstrate how remarkably simple and inexpensive it is to deploy a satellite monitoring system, whether it's for a bicycle winding through the hills of Northern France or a 608-ton fishing vessel plying the waters of the South Pacific for tuna. 
   
SkyTruth CTO Paul Woods is the brains behind putting Tony's path on the map. "It's a nice example of how easy it is for anyone willing to be transparent about their actions with a trivial investment of time and money."  

Some fishing vessels already employ AIS transmitters as a way of broadcasting their location to avoid deadly collisions at sea, but the use of AIS is not mandatory everywhere. 

"Imagine if every commercial fishing vessel were as trackable as Tony's bicycle. Overnight we could make it infinitely harder to hide illegal fishing," Woods said. 

Long agrees. "Tracking fishing vessels is a vital element of ending illegal activity – the only thing that is missing is the will to make it mandatory globally."

I am pleased to have SkyTruth’s emblem on my shirt,” Long said in an email several days before the challenge. "Having seen the great work SkyTruth are doing advancing tracking of fishing vessels from space I jokingly said 'Track my ride to Paris?' – I wasn’t expecting a reply of, 'of course!'"
