Japan's 7.6-magnitude earthquake lifted land out of the sea, extending parts of its coastline by as much as 820 feet

    Always appreciate scientific articles using the real universal measurements - American Football Fields. Quite interesting though.

    In some places, the earthquake extended the coastline by as much as 250 meters, or about 820 feet, according to a statement from the University of Tokyo. That's about the length of 2.2 American football fields.

      It's admittedly a bit stupid but it works. I was always taught to use measurements that are relatable when you're talking about sizes that become difficult to interpret.

      There's few things in my life that are 250meters long, and car speeds distort that distance, that two football fields is a decent point of reference for most.

          I've thought of that but decided against making the same point, I'm not American either, so the American football field size doesn't tell me much either.

          But I'm not their target audience. It'd be football pitches in European media (and it often is!) and they do it for the same reasons: putting large sizes into perspective.
          If that means football fields for the average person that's still helpful.

            In all honesty I'm totally unfamiliar with American football fields, but if they were to say "enough to build x single family homes on" or "enough land for x townhouses", wouldn't most people have a better idea?

              Single family homes can vary in size though, and there's also yardspace to consider. Like, would the houses in this example all be clustered together? How much space would be between them?...

              Football fields are a single uniform size and most Americans will have seen one at their schools, so it's an easy reference point.

                This is the key point. I think non-Americans have a hard time understanding the ubiquity of football-field comparisons but, like, the whole point of a football field is that it's 100 yards. The entire game is about gaining yards to get to the other side of those 100 yards. The field is even conveniently divided into 10-yard segments (seems more metric if anything, compared to our usual cacophony of 12 inches to a foot, 3 feet to a yard, and 5280 feet in a mile). Even if you've never watched football or don't know anything about it, the 100-yard thing has made comparisons to football fields common enough that most Americans know roughly how long they are in their minds.

                Notice how you never hear "2 basketball courts long" or "3 baseball fields wide" despite those also being extremely popular sports in America. It's because those sports aren't so heavily focused on the gaining of yards and first downs. The entire American football field is essentially a big ruler in a way that soccer/football pitches across Europe and the world aren't.

                  That aside, you're not wrong about the giant ruler part. American Football fields' 10yd marks are really easy to remember and use as estimation. As long as you're comfortable with yards that is.

                  Of all the types of sports grounds, they're probably one of the easiest to set up and can easily be used for other things. You just need a large stretch of flat grassy land, goal posts and paint to mark lines. I don't think my K-8 school even had permanent seating for it, they probably just brought out bleachers for games. I mainly remember using it in my gym class (usually for tag, not football) and field day.

    It's free real estate. Actually though, I wonder how stuff like land ownership or building permits work in cases like this.

      It depends on how the various levels of government attribute responsibility. If a city holds all the land between two points on the coast and back 20km, and suddenly there's more coast there, that's their luck and headache both. If there's no local government responsible for it, it's the province's to deal with as it pleases.
