quake

Earthquakes are examples of quakes, episodes of vibrations in a body, such as Earth, the Moon (moonquake), Mars (marsquake), the Sun (sunquake), or another star (starquake). For solid planets, the instruments that detect and measure them are termed seismographs or seismometers (the latter term can acknowledge that the instrument is not a "classic" seismograph that draws a graph on paper). The causes and types of vibration vary according to the body's structure:

• Observed earthquakes are a consequence of Earth's plate tectonics.
• moonquakes of a few kinds have been observed and measured, e.g., from meteor impacts.
• A marsquake has been detected.
• sunquakes occur during solar activity such as solar flares and coronal mass ejections.
• starquakes similar to sunquakes are undoubtedly common, as well as scaled-up quakes, e.g., in pulsating stars, and in stars undergoing short-term changes.
• neutron stars undergo starquakes, which can be detected in pulsars by their glitches (abrupt changes in their rotation rate).
