Is Yellowstone ground ever really at rest, or is it always scheming its next surprise? On April 10, 2025, geologists conducting routine maintenance in Norris Geyser Basin’s Porcelain Basin chanced ...

Infrasound is said to cause headaches and nausea that can last for days. At other times, it supposedly results in a feeling of generalized dread, sorrow, or fear.

Now, infrasound researchers wonder whether some animals can hear danger approaching. For instance, big storms such as hurricanes produce their own distinctive infrasonic signature.

Infrasound is also produced by storms, seasonal winds and weather patterns and some types of earthquakes. Animals such as elephants also use infrasound to communicate over long distances or as ...

Earth Science ‘Infrasound’ May Soon Help Scientists More Accurately Predict Tornadoes By Ryan F. Mandelbaum Published November 27, 2019 | Comments (0) 𝕏 ...

Infrasound waves have frequencies between about 0.01 hertz and 20 Hz — too low for humans to hear but audible to some animals including elephants (SN: 9/8/12, p. 11).

Infrasound signals generated by rising volcanic gases before an eruption could help volcanologists to better understand what is happening inside an active volcano.

In this work, we describe the development of a man-portable “tactical” infrasound field sensor array that is small, lightweight and can be rapidly set-up and torn-down as needed. The system is able to ...

Tracking this infrasound in real-time, using microphones similar to the ones custom-built and calibrated by the team at Boise State’s infrasound laboratory could help serve as a valuable early ...
