Damaging earthquakes that rocked West Texas in recent days were likely caused by oil and gas activity in an area that has weathered tremors for decades, according to the U.S. Geological Survey.

A sequence that began in 2021 erupted with its largest quake on Friday, a magnitude 5.1 in the most active area in the country for quakes induced by oil and gas activities, experts say. The recent quakes damaged homes, infrastructure, utility lines, and other property, weakening foundations and cracking walls and ceilings, officials said.

No injuries have been reported, the city of Snyder Office of Emergency Management said on Facebook. Officials declared a disaster in Scurry County.

“Safety is our top priority for all of our residents, and so we wanted to make sure we had all the available resources at our hands if we needed them,” said Jay Callaway, emergency management coordinator for the city of Snyder and Scurry County, of the disaster declaration. He added that despite resident concerns, a disaster declaration doesn't mean they were anticipating a “big one.” He said they continued to have small tremors on Monday.

There have been more than 50 earthquakes with a magnitude of 3 or larger — the smallest quakes generally felt by people are magnitude 2.5 to 3 — in the yearslong sequence, said Robert Skoumal, a research geophysicist with the USGS, in an email. A sequence is generally a swarm of earthquakes in a particular region motivated by the same activities, he said.

While Friday's was the largest in the sequence, officials have also recorded a recent 4.5, a 4.9 on July 23 and a 4.7 last year. A water line broke in the city of Snyder due to a quake last week, said Callaway, but it has been fixed.

“This particular portion of the Permian Basin has a long history of earthquakes induced by oil and gas operations, going back to at least the 1970s,” said Skoumal.

The Permian Basin, which stretches from southeastern New Mexico and covers most of West Texas, is a large basin known for its rich deposits of petroleum, natural gas and potassium and is composed of more than 7,000 fields in West Texas. It is the most active area of induced earthquakes in the country and likely the world, according to the USGS. The are many ways people can cause, or induce, earthquakes, but the vast majority of induced earthquakes in the Central United States are caused by oil and gas operations, Skoumal said.

Earthquakes were first introduced to the area via water flooding, a process in which water is injected into the ground to increase production from oil reservoirs.

Four other tremors larger than a magnitude 5 have rattled western Texas in the past few years. The biggest was a 5.4. “All four of these earthquakes were induced by wastewater disposal,” said Skoumal.

Further analysis is needed to confirm the specific cause of the region’s earthquakes, but because the area isn’t naturally seismic and has a long history of induced earthquakes, “these recent earthquakes are likely to also have been induced by oil and gas operations,” said Skoumal.

Oklahoma experienced a dramatic spike in the number of earthquakes in the early 2010s that researchers linked to wastewater from oil and gas extraction that was being injected deep into the ground, activating ancient faults deep within the earth’s crust. The wastewater is left over from oil and natural gas production and includes saltwater, drilling fluids and other mineralized water.

The large increase in Oklahoma quakes more than a decade ago led state regulators to place restrictions on the disposal of wastewater, particularly in areas around the epicenter of quakes. Since then, the number of quakes began to decline dramatically.

Houston Methodist leader on the push for sustainable health care and new local event

Q&A

Every industry can play a role in the energy transition, and Houston Methodist is leading the charge in the health care sector.

Culminating at this week’s inaugural Green ICU Conference, part of Houston Energy and Climate Startup Week, the health care system has spent the last three years taking a closer look at its environmental footprint—and showing other hospital systems and medical organizations how they too can make simple changes to reduce emissions.

The event, held tomorrow, Sept. 17, at TMC Helix Park, will bring together health care professionals, industry leaders, policymakers and innovators to explore solutions for building a more sustainable healthcare system.

In an interview with EnergyCapital, Dr. Faisal N. Masud, medical director of critical care at Houston Methodist and a champion for sustainability efforts across the system, shares the inspiration behind the event and what attendees can expect to take away.

Tell us about how the Green ICU Conference came to be.

Houston Methodist’s inaugural Green ICU conference is about three years in the making. It originated because Houston Methodist recognized the significant impact health care has on sustainability and the lack of similar initiatives in the U.S.

The Center for Critical Care at Houston Methodist launched a sustainability-focused ICU initiative, published a roadmap and became involved in international efforts to develop guidelines that many other organizations now use. Our work led to the creation of the first Green ICU Collaborative in the country, and the Green ICU Conference was established to share best practices and address the global impact of critical care on the environment.

What were some of the biggest takeaways from the collaborative, and how are they represented in this new event?

Through the Green ICU Collaborative, we’ve seen that health care professionals can make a significant impact on sustainability through simple, practical changes, and many solutions can be implemented without major costs or compromising patient care. Additionally, there’s a strong link between environmental stewardship and patient safety and quality. These lessons will be represented in the new Green ICU Conference by showcasing easy-to-adopt best practices, emphasizing the importance of sustainability in daily health care operations, and fostering a sense of shared responsibility among attendees to improve both patient outcomes and environmental impact.

Why are ICUs considered to be such carbon hot spots?

ICUs are considered carbon hot spots because they care for the sickest patients, requiring intensive therapies, numerous medications and a large amount of equipment, such as ventilators and pumps. This makes them the most resource- and energy-intensive areas in a hospital. A single day in the ICU can have a greenhouse gas impact equivalent to driving a car 1,000 kilometers.

The U.S. health care sector is responsible for approximately 8.5 percent of greenhouse gas emissions, and hospitals are the second-most energy-intensive commercial buildings in the country. With the Texas Medical Center being in the heart of Houston, it’s critical that health care organizations play a role in this area.

That’s why the Center for Critical Care launched a system-wide Green ICU Initiative with the Houston Methodist Office of Sustainability to help reduce our carbon impact and waste while continuing to provide unparalleled patient care. Innovation is part of our culture, and that extends into our sustainability efforts. Houston Methodist’s Green ICU initiative is the first-of-its-kind in the U.S.

What efforts has Houston Methodist taken to cut emissions?

The first step to cutting emissions is measuring an organization’s carbon footprint to determine the best path forward. Houston Methodist’s Office of Sustainability has aggregated two years of baseline emissions data pending third-party validation. The hospital has taken several steps to cut emissions, including implementing composting programs, installing solar panels, improving energy utilization and participating in global plastic recycling initiatives. These efforts are part of a broader commitment led by our Office of Sustainability to reduce the hospital’s environmental footprint.

Tell us a little more about the event. Who should attend? What do you expect to be some of the highlights?

The Green ICU Conference, taking place during Houston Energy and Climate Week, is focused on health care sustainability, bringing together health care professionals, engineers, experts and anyone interested in reducing health care’s environmental impact. With participants and speakers from six countries, the conference brings together leading experts who aim to raise awareness, share best practices and offer practical, easy-to-adopt solutions for making health care more sustainable.

Highlights include perspectives from leading voices in health care sustainability, real-world examples of successful sustainability initiatives and opportunities for networking and collaboration. Anyone interested in health care, sustainability,or making a positive impact in their community should consider attending.

And, because of increasing interest, we’ve opened up the opportunity for attendees to join virtually at no cost or in person.

What do you hope attendees take away? What are your major goals for the event?

The main goals of hosting the Green ICU Conference for the first time are to raise awareness about the environmental impact of health care; engage and empower attendees to implement easy, practical sustainability solutions; and foster a sense of shared community and responsibility.

I hope attendees leave the event feeling motivated and equipped to make meaningful changes in their own practices, whether that’s improving patient care, supporting their colleagues, or leaving their organization and environment in a better place for future generations.

Texas House Democrats urge Trump administration to restore $250M solar grant

solar grants

Eight Democratic members of the U.S. House from Texas, including two from Houston, are calling on the Trump administration to restore a nearly $250 million solar energy grant for Texas that’s being slashed by the U.S. Environmental Protection Agency (EPA).

In a letter to Lee Zeldin, head of the EPA, and Russell Vought, director of the federal Office of Management and Budget (OMB), the House members urged the two officials to reinstate the nearly $250 million grant, which was awarded to Texas under the $7 billion Biden-era Solar for All program. The Texas grant was designed to assist 28,000 low-income households in installing solar panels, aiming to reduce their energy bills.

“This administration has improperly withheld billions in congressionally appropriated funding that was intended to benefit everyday Americans,” the letter stated.

The letter claimed that numerous court rulings have determined the EPA cannot repeal already allocated funding.

“Congress made a commitment to families, small businesses, and communities across this country to lower their utility bills and reduce harmful pollution through investments in clean energy. The Solar for All program was part of that commitment, and the EPA’s actions to rescind this funding effectively undermine that congressional intent,” the House members wrote.

The six House members who signed the letter are:

  • U.S. Rep. Sylvia Garcia of Houston
  • U.S. Rep. Al Green of Houston
  • U.S. Rep. Greg Casar of Austin
  • U.S. Rep. Jasmine Crockett of Dallas
  • U.S. Rep. Lloyd Doggett of Austin
  • U.S. Rep. Julie Johnson of Dallas
  • U.S. Rep. Marc Veasey of Fort Worth

The nearly $250 million grant was awarded last year to the Harris County-led Texas Solar for All Coalition.

In a post on the X social media platform, Zeldin said the recently passed “One Big Beautiful Bill” killed the Greenhouse Gas Reduction Fund, which would have financed the $7 billion Solar for All program.

“The bottom line is this: EPA no longer has the statutory authority to administer the program or the appropriated funds to keep this boondoggle alive,” Zeldin said.
