Seismic

NASA’s InSight Mars lander has made two major new discoveries. By sensing seismic activity from the Red Planet, the craft has now detected a large meteorite impact, and found evidence of magma pools and volcanic activity still occurring today.

Predicting the likelihood and severity of earthquakes is important, but it’s hard to account for all factors. Researchers in New Zealand have now uncovered an overlooked factor that could affect the impact of the next big quake – tiny marine fossils.

NASA's InSight Mars lander is trading less life for more science after the space agency decided to let the spacecraft's remaining science instrument run until the lander's solar power system fails completely sometime in August or September.

NASA’s InSight lander has recorded the two strongest quakes detected so far on Mars, with both measuring over magnitude 4. These seismic events rolled in from the far side of the Red Planet, and one also clocked the record for longest marsquake.

NASA's InSight has provided … well, insight, into the inner workings of the Red Planet. By monitoring marsquakes over the past two years, the instrument measured the thickness and composition of Mars’ crust, mantle and core, revealing some surprises.

Scientists at the University of Utah have been keeping a close eye on these famous geysers of Yellowstone National Park, and have now managed to image the plumbing system of the tallest one in the world to a depth of 450 feet.

Oregon State University researchers have found that fin whale songs interact with the ocean floor, being reflected and refracted by the sediments and bedrock, and can be used to measure the thickness of these layers as well as providing other data.

Researchers have delved into what the coronavirus lockdowns have meant for human-caused Earth vibrations, leading to the discovery of what say is the "longest and most pronounced quiet period of seismic noise in recorded history.

As you might imagine, installing seismic sensors on the ocean floor isn't an easy task. Recently, however, scientists were able to detect seabed seismic activity using something that was already down there – a fiber optic telecommunications cable.

NASA has released a symphony of sounds captured by InSight on Mars including quakes, howling winds, metallic “dinks and donks” and other eerie sounds.

According to a new study, Earth's surface is smooth compared to the landscapes found deep within the planet. Using data from one of the biggest earthquakes on record, geophysicists have now found massive mountain ranges hundreds of kilometers beneath our feet.

​Although traditional seismographs are essential for warning of earthquakes, they can be difficult to access when placed on the sea floor. Well, that's where the MERMAID underwater seismic floats are designed to come in, and they've recently been successfully tested in the Galápagos.
