How seismometers record church bells ringing

A new study analyses the vibrations generated by the ringing of the bells to indicate the passage of time recorded by seismometers installed...

Thanks to COVID-19, nothing’s moving—and seismologists can tell

As COVID-19 continues to wreak its viral havoc on the human population of Earth, governments around the world have closed their schools, shut down...

Analyzing seismic patterns to forecast the magnitude of the largest earthquake...

Earthquakes can have devastating impacts on communities all around the world. They strike without warning, often resulting in large fatalities. Since the aftershocks that...

Underwater telecom cables make superb seismic network

Fiber-optic cables that constitute a global undersea telecommunications network could one day help scientists study offshore earthquakes and the geologic structures hidden deep beneath...

Studying the snowmelt episodes of a Pyrenean river with a seismometer

A team of researchers at Institute of Earth Sciences Jaume Almera of the Spanish National research Council (ICTJA-CSIC) have analysed the seismic signals generated...

Predicting the strength of earthquakes

Scientists will be able to predict earthquake magnitudes earlier than ever before thanks to new research by Marine Denolle, assistant professor in the Department...

Predicting seismic activity at fracking sites to prevent earthquakes

Scientists from the University of Bristol have found a more effective way to predict seismic activity at hydraulic fracturing sites, ensuring that potential earthquake...

Solving the salt problem for seismic imaging

The efficient extraction of oil and gas from within the Earth's crust requires accurate images of subsurface rock structures. Some materials are hard to...

Folding faults and seismic risk in the Kunlun range, Northwest Tibet

The tectonic deformation and growth pattern of the western Kunlun, which is the northwestern margin of the Tibetan Plateau, are not currently well understood....

Sun, moon and sea as part of a ‘seismic probe’

Using a single seismometer, researchers have shown that seismic waves excited by the surf, together with the effect of the Earth's tides on the...

Q&A: Creating a “Virtual Seismologist”

Understanding earthquakes is a challenging problem—not only because they are potentially dangerous but also because they are complicated phenomena that are difficult to study....

Seismic study reveals huge amount of water dragged into Earth’s interior

Slow-motion collisions of tectonic plates under the ocean drag about three times more water down into the deep Earth than previously estimated, according to...

Location of wastewater disposal drives induced seismicity at US oil sites

The depth of the rock layer that serves as the disposal site for wastewater produced during unconventional oil extraction plays a significant role in...

New approach offers high-resolution seismic monitoring of the shallow subsurface

Accurate monitoring of the ground beneath our feet for signs of seismic activity to identify natural phenomena such as earthquakes, volcanic eruptions and the...

Seismic analysis identifies 2017 North Korean nuclear explosion, collapse, earthquakes

Careful analysis of data collected after the 3 September 2017 North Korean declared nuclear test explosion has allowed seismologists to distinguish the separate seismic...

Regional seismic data help to locate September 2017 North Korean nuclear...

The epicenter of the 3 September 2017 nuclear test explosion in North Korea occurred about 3.6 kilometers northwest of the country's first nuclear test...

Seismic research cruise provides new data on US Atlantic margin gas...

Data acquired by the U.S. Geological Survey on the U.S. Atlantic margin in August 2018 reveal new information about the distribution of gas hydrates...

Study uses seismic noise to track water levels in underground aquifers

Seismic noise—the low-level vibrations caused by everything from subway trains to waves crashing on the beach—is most often something seismologists work to avoid. They...

Optimized positioning of geothermal boreholes reduces seismicity

When constructing geothermal systems for the extraction of heat from underground hot water reservoirs, optimal positioning of the boreholes can considerably reduce seismicity. This...

Scientists find seismic imaging is blind to water

When an earthquake strikes, nearby seismometers pick up its vibrations in the form of seismic waves. In addition to revealing the epicenter of a...
