You are an astronaut floating in the vacuum of space, about 100 feet from the space shuttle. You are out there taking a picture of the Earth with your digital camera. When you are finished you realize that the jet pack you use to move around in space is no longer working. You are stranded and everyone is a sleep in the shuttle. . Danny Hertel. EPS 109. Prof. . Militzer. Background/Method. As seismic waves travel through different mediums in the earth, the different mediums create different wave velocities. With geophones, the amplitude of the wave response can be measured at the surface and overlaid to create travel-time curves that tell what’s underneath.. . Razul. Overview of Molecular Dynamics .

All these records differ from those associated with terrestrial earthquakes in lacking S (secondary or shear) waves. They also last for much longer than earthquakes - up to an hour, as though the Moon were "ringing" like a bell. The bulk of the moonquakes originate from depths of 600 km or more (attributed to the seismic signals bouncing back and forth in the low velocity surface layers [. Part 1. Seismic Waves and Interior of the Earth. The behaviour of seismic waves in the different layers of the earth provides the most authentic evidence about the composition and structure of the earth. The different types of waves, generated during the occurrence of an earthquake, are generally divided into three broad categories: .
