Injecting wastewater from oil and gas activities underground caused 2012 Texas earthquake: Study

An earthquake of the 4.8 magnitude that caused massive destruction in Texas in 2012 happened due to human activity. Scientists have said that injection of large volumes of wastewater from oil and gas activities underground was responsible for the earthquake that destructed buildings and severely affected residents near the town of Timpson, Texas.

Study’s lead researcher William Ellsworth from Stanford University and team have taken the help of remote sensing technique known as Interferometric Synthetic Aperture Radar (InSAR) to reach at the conclusion.

New tool predicts earthquakes induced by effects of pumping wastewater from oil and gas operations

New tool predicts earthquakes induced by effects of pumping wastewater from oil and gas operations

A team of geophysicists has developed a new tool by which they can predict earthquakes that take place due to the effects of pumping wastewater from oil and gas operations deep underground. Japanese Advanced Land Observing Satellite (ALOS)’s interferometric synthetic aperture radar (InSAR) is an important addition to predict such human-caused events.

Alaska’s Pavlof Volcano may erupt by this year’s end

Alaska’s Pavlof Volcano may erupt by this year’s end

There is a possibility that the Mount Pavlof in Alaska could erupt for the third time this year by the end of 2016. Alaska Volcano Observatory (AVO) has based its predictions on the basis of increasing seismic activity and steam emissions from the volcano.

Owing to the release of a steady plume of steam from the mountain, state authorities have raised the alert level for the area from normal to advisory status, also known as yellow alert. The officials said that the level of seismic activity at Pavlof Volcano is elevated but is lower than recorded last day.

Scientists predict a tsunami May hit Hawaii

Scientists predict a tsunami May hit Hawaii

The University of Hawaii scientists have predicted that mega-earthquake in the Aleutian Islands would raise a 9% possibility for a tsunami to occur in Hawaii. The concern here is that is the state prepared to face the natural calamity?

The occurrence of earthquake is rare, but still there are chances that tsunami may hit the state. It is more frightening to think of a big one to strike. Last time a colossal tsunami triggered by a magnitude 9.0 earthquake hit eastern Japan in 2011. The impact of the calamity on the island nation is well known.

Frequent earthquakes of low magnitudes charge Mount St. Helens for another eruption

Frequent earthquakes of low magnitudes charge Mount St. Helens for another eruption

Since the massive volcanic eruption that took place at Mount St. Helens on May 18, 1980, the area has been actively monitored by researchers and local authorities. The United States Geological Survey (USGS) has detected over 130 earthquakes from below the grounds of Mount St. Helens since March 14. The most concerning to the researchers is the frequency at which the quakes are occurring. The agency reported that the frequency had reached almost 40 quakes per week.

La Habra earthquake’s impact could produce more quakes in future

La Habra earthquake’s impact could produce more quakes in future

NASA carried out a study on an earthquake happened in 2014. Researchers shared that earthquake in La Habra deformed earth’s crust in a bigger area of northern Los Angeles and northern Orange County than expected before. Also, strain due to the earthquake is present in deeper area faults that raise the risk of further earthquakes.

Lack of communication in Alaska plane crash an issue for families

Lack of communication in Alaska plane crash an issue for families

According to families who heard regarding the small Alaska sightseeing plane crash, it was possible to have a better communication with officials. As per Pat Thompson, he tried to contact his son through cellphone. He said that he even tried calling on a number of sales department of the cruise line but it didn't help.

After that he reached an Alaska State Trooper in Ketchikan after getting a family-line number for Holland America. He was finally told that his son was not on the plane that crashed and boarded a different plane.

Study Blames Sixth Extinction of Vertebrates on Humans

Study Blames Sixth Extinction of Vertebrates on Humans

In a new study, published Friday in the journal Science Advances, researchers from the Stanford University in California have warned of a sixth mass extinction of animals that is ensuing, owing to the unrestrained human activity that has inflicted massive damage to animal habitat.

20 endangered homes on Topsail Island's northern tip to be saved by using sandbags

20 endangered homes on Topsail Island's northern tip to be saved by using sandbags

Around 20 homes situated along one of North Carolina's most fragile barrier islands will be saved by waves with the help of supersized sandbag wall that is being built there.

These homes are situated on Topsail Island's northern tip. The News & Observer of Raleigh reported that currently the crews are building a 9-foot-tall wall of sandbags to save these homes from collapsing. The allowance for this set up was given by state's Coastal Resources Commission because of the fact that the wall so constructed will be 3 feet taller than the maximum allowed height.

Radiation risk from Fukushima disaster drifts across Pacific

Radiation risk from Fukushima disaster drifts across Pacific

A study based on recent data has pointed towards the fact that radiation from the Fukushima nuclear power plant disaster has now drifted across the Pacific. With this news, there are fears that this radiation could be spread along the British Columbia coast and it might prove to be very harmful for salmon and other marine life.
