Following up on recent reports of oil in the water off the north coast of Karawang Regency, West Java, Indonesia, SkyTruth has picked up a slick in Sentinel-1 radar imagery. In the image from July 18th, an unidentified platform (circled in red) located roughly 12 km north of the Karawang shore is shown emitting a 34.7 km-long slick into the Java Sea. A story written by the local Jakarta Post on July 18th describes state-owned energy firm Pertamina’s decision to evacuate personnel and halt operations at an offshore production rig in their Offshore Northwest Java (ONWJ) block. The evacuation was ordered after a dangerous “well kick”, or unplanned release of gas caused by low pressure in a wellbore, initiated a large slick on the 16th of July. A separate report released by the Jakarta Post five days later indicated that the Indonesian Transportation Ministry teamed up with Pertamina in response to the oil-related event, along with several other smaller entities in the area. The response vessels were able to set up a boom around the perimeter of the offshore platform. Unfortunately, this didn’t stop oil from reaching villages and beaches on West Java’s coast. Given the fact that several vessels surround the unidentified object in the Sentinel-1 image, we believe that this could be the affected drilling platform. Pertamina’s upstream director Dharmawan Samsu estimated that it will take approximately eight weeks for the oil and gas leakage to be plugged.
- SkyTruth is looking for new sources for the environmental alerts we send out.
- Since relaunching Alerts in December, 2018, we’ve expanded Oil & Gas permitting to include West Virginia, Colorado, Wyoming, New Mexico, Montana and Utah. We’ve also added pollution alerts for Florida, New Mexico and New York.
- We rely on our users to let us know about potential new sources for Alerts. Email your ideas to firstname.lastname@example.org.
Where do you start if you want to monitor the environment in an area that’s special to you? How do you find useful data? You might have a specific issue in mind and you suspect there’s relevant data online if you could only find it. Data.gov alone contains 252,892 datasets last time you checked, and much of that’s related to the environment.
You could spend days researching online datasets, and when you find something relevant figure out how to navigate the website to pull out the data you need while somehow filtering for your Area of Interest (AOI). Repeat daily.
Or, you could register for a SkyTruth Alerts account, outline and save your AOI, then go live your life while we do the heavy lifting.
SkyTruth Alerts was built in 2012, originally as an in-house tool for our staff to automate receiving notifications of incidents reported to the Coast Guard’s National Response Center (NRC). The NRC is a federal emergency call center that fields initial reports for pollution and railroad incidents. They make updates available usually once a week, which we then download and add to our database. SkyTruth Alerts was soon thereafter made available to the public and expanded to include Pennsylvania Oil & Gas Permitting events, which we “scrape” from PA’s Dept. of Environmental Protection website several times a day. SkyTruth makes Alerts available to anyone, and at no charge, for the purpose of providing access to tools, data and satellite imagery that environmentalists otherwise wouldn’t have.
In 2018, Alerts was given a facelift and SkyTruth began looking for additional datasets that would help subscribers monitor their AOIs. We’ve since expanded Oil & Gas permitting to include West Virginia, Colorado, Wyoming, New Mexico, Montana and Utah. We’ve also added pollution alerts for Florida, New Mexico and New York.
Alerts In the Big Picture
Alerts is an environmental monitoring platform. In addition to receiving incident emails, users also have access to satellite imagery, relevant map layers, and the ability to annotate and share map views. Alerts is not a research platform — there are websites that do a great job with this (World Resources Institute, for one). And while we have some of the tools that allow you to monitor a species, we’re not really designed to do this task which, by the way, is already very aptly handled by sites such as iNaturalist.org. At the same time, if there’s a map layer that will help you monitor your AOI, let us know about it and we’ll see if it can be added to the set of layers we make available.
Getting Started with Alerts
- If you haven’t already done so, register for an account.
- Identify your AOI(s).
- Identify the Alerts you want to receive.
- Check your email for new alerts.
What About Dataset XYZ?
We are always on the lookout for new datasets that can be a source for new Alerts, and we depend on our subscribers to help find these sources. If a dataset is important to you, it might also be important to others and we’d like to learn more. Email us at email@example.com.
The number one requirement for an Alerts source is that the data must be available online. After that, to be meaningful the source needs to be related to the environment, have location information such as latitude/longitude or address, and include a date such as the incident date. Alerts don’t have to be about incidents that have already occurred. We’re also interested in new alert sources that would drive people to take action before there’s harm to the environment. Think upcoming hearings, permitting processes, etc. If the data’s online somewhere, it might make a relevant SkyTruth alert.
Our current plans are to add more oil and gas permitting states, pollution incidents and federal datasets such as those from the EPA. We love hearing from our subscribers about potential new sources and how they can be useful, and the more people who might use a source, the more likely we can add it to our database.
SkyTruth may soon be its own source of Alerts. Over the years we’ve compiled some unique datasets such as our global flaring data, which dates back to 2012. New flaring in an AOI equals a new alert, right? That’s the plan! We’re also working on algorithms that will automatically identify changes in the environment and our strategic plan includes feeding the results of Conservation Vision into Alerts. Stay tuned for progress on these fronts!
SkyTruth’s latest update to Alerts adds features that allow subscribers to annotate a map view and share it with co-workers, organizations and interested parties. These additions add to a rich set of features that are unique to online mapping and satellite imagery viewing — all available for free to the public.
- Highlight traits found in satellite imagery
- Measure the area of new development or changes in a habitat’s footprint
- Add information to a SkyTruth Alerts incident
- Measure boundary setbacks or the distance between 2 objects
- Add text to the map in preparation for sharing with others
This is accomplished with a set of tools that can annotate by using shapes (rectangles, circles, polygons), lines, text, markers and measurements. A guide to these tools is available here.
New sharing capabilities allow you to save current map views either as a JPG image or a unique URL. Visit here for a guide to sharing and some of its limitations.
The full online manual is available here.
We’ll be testing and fine-tuning these features throughout the summer. If you run into problems or want to suggest features you’d like to use with Alerts, please contact us at firstname.lastname@example.org. We would also enjoy hearing about how you’re able to make use of these features!
If you have been following the first two posts in this series, you have been introduced to Pennsylvania’s hottest commodity: natural gas. The state has experienced a drilling boom with the development of the Utica and Marcellus shale formations, which underlie approximately 60% of the state. With Dry Natural Gas reserves estimated around 89.6 trillion cubic feet in 2017 (roughly ⅕ of the US total), natural gas development will likely play a big part in Pennsylvania’s future. The method for extracting natural gas from porous rock underneath the Earth’s surface, usually horizontal drilling paired with hydraulic fracturing (or “fracking”), is an extremely disruptive industrial process that could present significant human health and environmental repercussions (see also this compendium of public health studies related to fracking). Allegheny County, the focal point of SkyTruth’s previous analyses, has survived largely unscathed to this point, but developers have high hopes of expanding into the county.
In order to see just how quickly natural gas development can expand, Allegheny residents need not look far. Allegheny’s neighbor to the south, Washington County, has become a critical site of natural gas production for the state of Pennsylvania. Not only does Washington County rank second in production among all Pennsylvania counties, but it also recently moved ahead of Susquehanna County as the home of the most active wells in Pennsylvania. Washington County is considered a part of the Pittsburgh metropolitan area, with a population of approximately 207,000. Though this is a fraction of the population of Allegheny County, its close proximity could prove indicative of what is to come in the county if stricter regulations are not put in place. In our final entry of this series, we will examine the expansion of drilling and fracking in Washington County, with eyes toward how the trends here might carry over to Allegheny County.
The area shown above lies close to the town of West Finley, PA and surrounds the perimeter of the Four Seasons Camping Resort (shown in the center of this image series). This area is right on the PA/WV border, within the heart of the Utica and Marcellus formations. These images show the growth of drilling infrastructure in a relatively low population setting.
The image above (courtesy Google) gives us a closer look at one of the drilling fluid impoundments which can be seen at the top left corner of the previous scene. SkyTruth recently wrapped up its 2017 FrackFinder update, which mapped the extent of new drilling in Pennsylvania between 2015 and 2017. According to our findings, the average size of one of these impoundment is 1.4 acres, slightly larger than the average football field. These ponds sometimes hold fresh water, and at other times are temporarily storing leftover fluid used in the hydraulic fracturing process which can contain volatile, toxic chemical additives.
This second area sees significant well pad development from 2008 to 2017. Located right outside the small town of Bentleyville, PA, several wells are constructed along this bend of I-70. This area is made up of former coal towns. Mining facilities dot the landscape, indicating that residents of this area are no strangers to resource extraction.
This third series of images shows the massive development of the agricultural land surrounding Cross Creek Lake, located right outside of West Middletown. Cross Creek County Park (outlined in black), which encompasses the lake and its surrounding area, is the largest park in the county and serves as a convenient day retreat for residents of the city of Washington, PA, Washington County’s largest city. Many people come to the lake to fish, but the fracking operations in the park could prove to be detrimental to the health of the lake’s fish, according to recent research.
This close-up on an area at the Southwestern portion of the park (courtesy Google Earth) shows a children’s playground that lies just under 1500 feet away from an active drilling site (at lower right). This is well within the proximity suggested to be potentially hazardous to public health.
This final image series is taken from right outside the Washington County towns of McGovern and Houston. The drilling operations, which pop up in just four years, are located in close proximity to developing neighborhoods, parks, The Meadows Racetrack and Casino, and the Allison Park Elementary School. Unlike the other images depicted throughout this evaluation, this development takes place around a well established suburban area, where public safety could be at risk should disaster strike at one of these drilling locations.
The image above (courtesy Google) presents yet another example of just how close these drilling sites are built to residential areas in some instances. Massive industrial development could be seen and heard from one’s back porch!
This is all happening directly south of Allegheny County, so it is plausible that similar development could take place there.
Allegheny County is in an unique situation given its location, its population density, and its relatively low levels of natural gas development. As pressures on Allegheny County mount, we hope that these bird’s eye view evaluations of drilling in nearby counties will help to enlighten and inform policy moving forward.

If you have read the first entry in this series, you have been introduced to the situation that Allegheny County, PA currently finds itself in. Hydraulic fracturing (or “fracking”) paired with horizontal drilling has become a well established method for breaking natural gas out of porous, but impermeable, rock formations like shale and silty sandstone. Pennsylvania has been inundated with these fracking operations over the past decade following the discovery of the massive gas reserves located in the Utica and Marcellus Shale formations. Although this discovery has led to a booming industry in Pennsylvania, these activities have also had adverse public health and environmental consequences.
Susquehanna and Bradford Counties in the northern portion of the state are two examples of areas that have been heavily developed with natural gas wells and facilities. According to a report issued by the Pennsylvania Department of Environmental Protection (PA DEP) in August of 2018, not only is Susquehanna County the largest producer of natural gas in the state, but it also accounts for 4% of the United States’ natural gas production. The same report points to Bradford County as the fourth largest natural gas producing county in the state, accounting for 13% of the state’s production. Although these two counties are both considered to be rural (their populations combined equal to roughly 8% of the population of Allegheny County, per the 2010 Census), the intensity of industrial infrastructure development across their landscapes has been astounding. In this post, we will look at the footprint the energy industry has created in both counties.
Figure 1 (shown above) gives an example of the development taking place in Susquehanna County. This time-series shows the expansion of wells over a seven year period in New Milford Township. The once agriculturally-dominated area is markedly changed by the introduction of gas drilling: new roads, fracking fluid impoundments, and supporting facilities carve up the landscape.
Figures 2(a) and 2(b) depict a very rapid expansion of drilling in Bradford County. Located between Troy Township and West Burlington Township, we’re able to see the development of ten new drilling sites in a 32 square kilometer area over just two years. These sites may have played a role in the 2.6 billion cubic feet (Bcf) of natural gas generated per day by Bradford County, according to the PA DEP’s August 2018 report.
Figure 3 shows an area near the city of Sayre in Bradford County. Situated along the border of New York and Pennsylvania, eight new drilling sites are developed between 2010 and 2013, along with subsequent roads and fracking fluid containment ponds. Drilling in these two counties is significant and — without a change in policy — could serve as a glimpse into Allegheny County’s drilling future.
