Great Hanshin Earthquake - Seismic Intensity

Seismic Intensity

It was the first time that earthquake tremors in Japan were officially measured at seismic intensity (shindo in Japanese) of the highest Level 7 on the scale of Japan Meteorological Agency (JMA).

Note: After this earthquake, seismic intensity observation in Japan was fully mechanized (from April 1996) and JMA seismic intensity Levels 5 and 6 were each divided into 2 levels (from October 1996).

An on-the spot investigation by JMA concluded that tremors by this earthquake were at seismic intensity of

Level 7 in particular areas in northern Awaji Island (now Awaji City) and in the cities of Kobe, Ashiya, Nishinomiya and Takarazuka.

Tremors were valued at seismic intensity of Levels 6 to 4 at observation points in Kansai, Chūgoku, Shikoku and Chūbu regions.

Level 6 in the cities of Sumoto (in Awaji Island) and Kobe (both in Hyōgo Prefecture).
Level 5 in the cities of Toyooka (in Hyōgo Prefecture), Hikone (in Shiga Prefecture) and Kyoto.
Level 4 in the prefectures of Hyōgo, Shiga, Kyoto, Fukui, Gifu, Mie, Osaka, Nara, Wakayama, Tottori, Okayama, Hiroshima, Tokushima, Kagawa and Kōchi.

Famous quotes containing the words seismic and/or intensity:

    Most near, most dear, most loved and most far,
    Under the window where I often found her
    Sitting as huge as Asia, seismic with laughter,
    George Barker (b. 1913)

    We may say that feelings have two kinds of intensity. One is the intensity of the feeling itself, by which loud sounds are distinguished from faint ones, luminous colors from dark ones, highly chromatic colors from almost neutral tints, etc. The other is the intensity of consciousness that lays hold of the feeling, which makes the ticking of a watch actually heard infinitely more vivid than a cannon shot remembered to have been heard a few minutes ago.
    Charles Sanders Peirce (1839–1914)
