    was the first person to study earthquakes
  • Period: to

    history of seismology

  • Seismometer

    Luigi Palmieri created the first electric seismometer that could record the time of an earthquake.
  • Mallet's Theory's

    Mallet's Theory's

    The Irish scientist and engineer; Robert Mallet went to Naples after a incredibly strong earthquake devastated the land to research earthquakes. His research provided us with many early theories about seismology, such as the idea that earthquakes move outward from a central focus point, and that by finding out which direction the earthquake came from, then the focal points could be located.
  • Grove Gilbert's Discovery

    Grove Gilbert's Discovery

    discovered that earthquakes occur around a fault line.

  • The First True Seismograph

    Italian physicist Filippo Cecchi created the first seismograph that detected and recorded earthquakes.
  • Mercalli Intensity Scale

    Mercalli Intensity Scale

    was a seismologist who created a scale that could measure the intensity of an earthquake, as well as the damage done by it.
  • The Moho Boundary

    The Moho Boundary

    The boundary between the crust and the mantle is the Moho boundary. Seismic waves change velocity at that depth.

  • The Richter Scale was created

    The Richter scale was created by Charles Francis Richter and measures the strength and magnitude of earthquakes using numerical values.
