  2. Japan Meteorological Agency seismic intensity scale

    en.wikipedia.org/wiki/Japan_Meteorological...

    The Japan Meteorological Agency (JMA) Seismic Intensity Scale [1] (known in Japan as the Shindo seismic scale) [2] is a seismic intensity scale used in Japan to categorize the intensity of local ground shaking caused by earthquakes. Map of Japan showing the distribution of maximum JMA Seismic Intensities by prefecture for the 2011 Tōhoku ...

  3. Modified Mercalli intensity scale - Wikipedia

    en.wikipedia.org/wiki/Modified_Mercalli...

    The Modified Mercalli intensity scale (MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth.

  5. Seismic magnitude scales - Wikipedia

    en.wikipedia.org/wiki/Seismic_magnitude_scales

    (These should not be confused with moment magnitudes JMA calculates, which are labeled M w (JMA) or M (JMA), nor with the Shindo intensity scale.) JMA magnitudes are based (as typical with local scales) on the maximum amplitude of the ground motion ; they agree "rather well" [ 22 ] with the seismic moment magnitude M w in the range of 4.5 to 7. ...

  7. Table of explosive detonation velocities - Wikipedia

    en.wikipedia.org/wiki/Table_of_explosive...

    The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation pressure. The pressure can be calculated using Chapman-Jouguet theory from the velocity and density.

    Shindo or Shindō may refer to: Japan Meteorological Agency seismic intensity scale ( 震度 , shindo ) Shindo (religion) (신도), an alternative name of Korean Shamanism used by Shamanic associations in modern South Korea.

  9. Seismic source - Wikipedia

    en.wikipedia.org/wiki/Seismic_source

    An air gun seismic source (30 litre) A seismic source is a device that generates controlled seismic energy used to perform both reflection and refraction seismic surveys. A seismic source can be simple, such as dynamite, or it can use more sophisticated technology, such as a specialized air gun.
