Q:

What are L waves?

A:

L waves, also known as long waves, are surface waves created by earthquakes. They are the slowest of all earthquake waves, but usually cause the most intense shaking and damage to property.

Full Answer

L waves are categorized as either Love waves or Rayleigh waves according to their motion. Love waves move side to side across the surface of the earth, while Rayleigh waves have a rotating circular motion.

Waves that occur below the surface of the earth are called body waves. Primary body waves are the fastest waves and are able to pass through solids, liquids and gases. Secondary body waves move more slowly and can only travel through solids.

  • Q:

    Why do earthquakes happen?

    A:

    Earthquakes are the result of two of the Earth's crustal plates slipping past each other, otherwise known as plate tectonics. The vibrations caused by this sudden movement reverberate through the surrounding rock structures, and they are felt as tremors. Earthquakes are most common among the geologically active regions at the borders between plates of the Earth's crust, also known as fault zones.

    Who studies earthquakes?

    A:

    A person who studies earthquakes is known as a seismologist. In addition to studying earthquakes, a seismologist also studies different vibrations in the Earth. These specialists use sophisticated tools, such as seismographs, to measure the intensity of vibrations. They also use specialized computers to create graphical models of earthquakes.
