Over the last 10 years, Texas has experienced a massive upsurge in earthquakes linked to oil and gas activity. Now, research is showing how that activity can wake up fault lines that were “dead” for hundreds of millions of years.

The same fault that produced the 4 magnitude earthquake in May 2015 in Johnson County — the strongest ever recorded in North Texas — could create an even larger one in the future, a recent study has found.

A magnitude 7.3 earthquake that struck northern Iraq and parts of Iran has killed more than 400 people in both countries and injured more than 6,000, according to officials. It is the strongest quake to hit the region in years.

A major earthquake-monitoring network is up and running across Texas.

Thanks to an interactive website hosted by TexNet, you can now see where quakes are happening and learn about them in real time. The tool could be useful for the growing number of people who’ve felt earthquakes here.

In the eight days since a massive earthquake leveled dozens of buildings across central Mexico, rescue workers and volunteers have scrambled through debris in a desperate search for any signs of survivors. And those efforts, which drew support from at least 43 different countries, were not in vain: Some 70 people were pulled alive from the rubble of their broken buildings.

Back-to-back natural disasters in Mexico and across the Caribbean have left millions of people reeling.

A strong earthquake that hit Mexico City and other central areas has killed at least 273 people, officials say. Search teams are working feverishly to find any survivors who were trapped.

The head of Mexico's civil defense agency has lowered the number of people confirmed dead in Tuesday's earthquake. Luis Felipe Puente now says 217 people were killed. Earlier he said the death toll was 248. He gave no explanation for the revised number.

The death toll continues to rise in Mexico after Tuesday's earthquake. The country's national civil defense agency confirmed the death toll stands at 248. Rescue teams are digging through the rubble to find survivors.

The most powerful earthquake to hit Mexico in decades struck late Thursday off the country's southern coast and could be felt hundreds of miles away in the capital. The 8.1 magnitude temblor is blamed for killing at least 60 people.

The quake triggered fears of a tsunami, although no major damage was reported. The event came as the country already was bracing for Hurricane Katia, which made landfall Saturday night in the state of Veracruz as a Category 2 storm.

The science on whether there's a link between oil and gas activity and a surge in earthquakes in Texas isn't clear-cut, says the new seismologist for the agency that regulates the industry here.

Over the last several years, scientists, including those at the U.S. Geological Survey and the Environmental Protection Agency, have linked an increase in earthquakes in Texas to oil and gas activity. But, industry and Texas state regulators remain reluctant to publicly acknowledge it.  Now, a study that looks at the quakes from space might put more pressure on them to do so.

The Oklahoma Corporation Commission has directed dozens of wastewater disposal wells within an approximate 500-square-mile radius of the epicenter of the Oklahoma earthquake to shut down.

EPA: North Texas Earthquakes Likely Linked to Oil and Gas Drilling

Federal regulators believe “there is a significant possibility” that recent earthquakes in North Texas are linked to oil and gas activity, even if state regulators won’t say so.

There’s a been a lot of debate about what has caused the swarm of earthquakes in North Texas. A new study from the University of Texas at Austin and Southern Methodist University says humans are likely behind the quakes – not just in recent years, but for nearly a century.

Five stories that have North Texas talking: Three Dallas neighborhoods are considered foot-friendly; Rick Perry endorsed Ted Cruz, but didn’t vote for him; a Texas woman died in the Brussels attacks; and more.

 

Some parts of Oklahoma and Texas now have about the same risk of an earthquake as parts of California, according to the U.S. Geological Survey.

The big difference is, the quakes in Oklahoma and Texas are "induced" — they're caused by oil and gas operations that pump wastewater down into underground wells.

North Texas At Higher Risk Of Damaging Earthquakes Than Ever Before, Report Says

Federal scientists now say Dallas-Fort Worth is at a higher risk of damaging earthquakes than ever before.

The death toll continues to climb from the massive earthquake that rocked northeast Afghanistan near its border with Pakistan. More than 260 people are confirmed dead across the region with the majority of the reported casualties in Pakistan.

The epicenter of the magnitude 7.5 earthquake struck a remote area of Afghanistan but could be felt across the region as far north as Tajikistan and as far south as India.

The regulatory agency overseeing Texas' oil and gas industry says a series of small earthquakes in North Texas likely wasn't caused by drilling operations by an Exxon Mobil subsidiary.

When the first earthquake hit Nepal in late April, the impact reached all the way to North Texas. Worried Nepalese-Americans checked in with friends and family. They organized relief efforts. A second earthquake struck a couple of weeks ago.

What’s causing the Azle earthquakes? SMU researchers say that wastewater injection and saltwater extraction from natural gas wells is the most likely cause.

Southern Methodist University seismologists have determined that the recent earthquakes that have rattled North Texas were concentrated along a two-mile line that indicates a fault from Irving into West Dallas.

Texas Lawmakers Consider Boosting Earthquake Research

State lawmakers are considering a nearly $2.5 million plan to help answer a pressing question in some Texas communities: Why does the ground keep shaking?

The cities of Dallas and Irving took a first step toward an earthquake task force Monday with an afternoon conference call that included experts from the US Geological Survey. Seventeen small quakes have hit the Irving area around state highways 114 and 183 in the past week. Several of them were big enough to startle neighbors in Dallas and elsewhere.

Another small earthquake vibrated Irving Sunday night: a magnitude of 2.5 at 7:46 p.m., according to the U.S. Geological Survey. That makes 17 in the last week in North Texas, most of them around the old Texas Stadium site in Irving.  As the quakes continue, speculation circulates as to what's causing them.
