Definition of seismicity in English:



  • The occurrence or frequency of earthquakes in a region.

    ‘the high seismicity of the area’
    • ‘Here, according to most of the authors, active extension is dominant over the whole chain, as shown by breakout data and seismicity, as well as by geological and geomorphological analyses.’
    • ‘The adjacent regions to east and west lack significant seismicity, except in the south, where the belt broadens over southeastern England to join the separate line of earthquakes along the North Sea rift zone.’
    • ‘Because the bridge is not situated in an area of high seismicity, the earthquake load was not significant and was not a controlling load in the design.’
    • ‘Conversely, when specific seismogenic fault zones have been considered, statistical links between seismicity and eruptive processes are found.’
    • ‘Although the rate of seismicity has declined since the April 6th peak, earthquakes are still occurring frequently, and steam and ash emissions and small explosions are likely to occur.’
