Intensity 7 (震度7, Shindo-nana) is the highest level on the JMA seismic intensity scale, applied to earthquakes with an instrumental intensity (計測震度) of 6.5 or higher. [6] At Intensity 7, movement becomes nearly impossible without external support. [11] The intensity was created following the 1948 Fukui earthquake.
The JMA announced the Earthquake Early Warning hit (accuracy) rate for the 2011 fiscal year on 31 May 2012. The hit rate is the percentage of warnings issued immediately on the detection of P-waves with a Japan Meteorological Agency seismic intensity scale (震度, shindo) number (0 to 7) within one shindo number of the measured earthquake.

Also, construction codes and methods have evolved, making much of built environment stronger; these make a given intensity of ground shaking seem weaker. [15] Also, some of the original criteria of the most intense degrees (X and above), such as bent rails, ground fissures, landslides, etc., are "related less to the level of ground shaking than ...
The reverse-faulting shock achieved a maximum JMA seismic intensity of Shindo 7 and Modified Mercalli intensity of X–XI (Extreme). The shaking and accompanying tsunami caused widespread destruction on the Noto Peninsula, particularly in the towns of Suzu, Wajima, Noto and Anamizu. Damage was also recorded in Toyama and Niigata prefectures.
Tertiary explosives, also called blasting agents, are so insensitive to shock that they cannot be reliably detonated by practical quantities of primary explosive, and instead require an intermediate explosive booster of secondary explosive. These are often used for safety and the typically lower costs of material and handling.
Series 5 tests are used to determine if an article can be assigned to HD1.5 'Very Insensitive Explosive'; series 6 tests are used to determine the classification of an article within Hazard Divisions 1.1, 1.2, 1.3, or 1.4; and series 7 tests are used to determine if an article can be assigned to HD 1.6 as an article containing predominantly ...
