In this lesson, students learn about different types of seismic waves on the basis of where and how the waves move. In addition, students discuss how scientists use earthquake waves to investigate ...

Seismic readings of the interior of Mars strongly suggest large quantities of water buried 6 to 12 miles underground.

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic field.

Mars might hold enough subsurface water to cover its surface in a global ocean between 0.62 to 1.24 miles (1 to 2 kilometers) ...

When this happens, they release seismic waves that propagate through the subsurface. Mars, however, lacks plate tectonics. So marsquakes must come from different sources, like meteorite impacts or ...

Are subterranean lifeforms viable on Mars? A new interpretation of Martian seismic data by scientists Ikuo Katayama of Hiroshima University and Yuya Akamatsu of Research Institute for Marine ...

When the waves cross the boundary between two different layers ... It is the slowest of the three types of seismic wave. Surface waves usually have larger amplitude than the other waves and ...

The mantle of the Earth, up to 1,800 miles (2,900 kms) thick and 84% of the Earth's volume, was assumed to be a simple ...

Most scales are based on the amplitude of seismic waves recorded on seismometers ... video uses the analogy of a lightbulb to explain the how an earthquake can have different intensities at different ...

For example, S-waves cannot travel through ... Experimentation revealed that the seismic velocities of the dry, wet, and frozen samples are significantly different, which supports the ...
