The Ontong Java Plateau (OJP), located in the Pacific Ocean, formed around 110 to 120 million years ago through massive submarine volcanic eruptions. This event is considered the most extensive ...

In May 1997, a large earthquake shook the Kermadec Islands region in the South Pacific Ocean. A little over 20 years later, in September 2018, a second big earthquake hit the same location, its waves ...

The earliest scientists first observed the waves that earthquakes produce before they could accurately describe the nature of earthquakes or their fundamental causes, as discussed in Lessons 1–5.

The NASA lander is on its last legs, but it's still revealing details about Mars’ volcanism, seismology, and even recent meteorite impacts. Reading time 4 minutes NASA’s InSight lander, a mission ...

Scientists have detected sound waves moving through Mars’ core for the first time, offering new clues to the composition of the fourth planet from the Sun. The now-decommissioned InSight lander ...

Seismological research is directly related to the incubation, occurrence, and evolution of earthquakes. Scientists seek to reveal potential earthquake precursors by monitoring the stress state of ...

Scientists successfully addressed mathematical challenges in conventional Spectral Matrix analysis, used to analyze three-component seismic signals, by introducing time-delay components. The new ...
