The seismicity of Mars

On 26 November 2018, the NASA InSight lander successfully set down on Mars in the Elysium Planitia region. Seventy Martian days later, the mission's seismometer SEIS began recording the planet's vibrations. A team of researchers ...

Geothermal energy: Drilling a 3,000-meter-deep well

Although stopping climate change is challenging, it is imperative to slow it down as soon as possible by reducing greenhouse gas emissions. But how can we meet the growing energy demand while reducing our use of polluting ...

Using submarine cables to detect earthquakes

Installing seismic sensors on the ocean floor can be a difficult and expensive task. But what if seismic activity could be monitored by using something that's already down there – pre-existing submarine telecommunications ...

Experts seek answers behind constant quakes in Puerto Rico

Seismologists in southern Puerto Rico gingerly walked around a patch of dirt that marks the location of recently buried sensors they hope will reveal answers behind the constant and unusual shaking in the region that has ...

Formation of a huge underwater volcano offshore the Comoros

A new submarine volcano was formed off the island of Mayotte in the Indian Ocean in 2018. This was shown by an oceanographic campaign in May 2019. Now, an international team led by the scientist Simone Cesca from the German ...

Scientists find iron 'snow' in Earth's core

The Earth's inner core is hot, under immense pressure and snow-capped, according to new research that could help scientists better understand forces that affect the entire planet.

Submarine cables: billions of potential seismic sensors

Scientists have for the first time shown that it is possible to detect the propagation of seismic waves on the seafloor using submarine telecommunications cables. According to their observations, this existing infrastructure ...
