One way to describe the destruction cause by earthquakes it to use what is called the Modified Mercalli Intensity Scale. The airtightness and aerodynamic design of the Shinkansen made it possible to make the facilities compact compared to high-speed rail systems elsewhere; for example, small-sized tunnels, compact layout, and a short distance between tracks. In this article, I attempt to focus on the chronology of seismic imaging. Such innovative technology shows that the relationship between Japan and earthquakes--although certainly frightening at times--has produced some useful technology that can help save lives.

The intensity of an earthquake is measured using the term "magnitude", while the impact of the earthquake that can be felt is measured on the "seismic intensity scale." Unsecured furniture may shift. Here in the United States, we look to the Western part of our country to see the greatest seismic activity. One was a 6-magnitude and one was a 6.3. Also, I think the article's title should be revised to Japan Meteorological Agency Seismic Intensity Scale (note capitalization: if the JMA's English website is anything to go by, this is the scale’s official name, making it a proper noun); but I don’t know how to make this change myself.
