I am still learning how to interpret the data on that Data.html Web page. For example, on the previous Web page which was posted around August 10 there was just 1 earthquake entry for the area around 175W longitude. With this latest Web page there are 9 earthquakes listed for that area. If any of them were listed in my database as being destructive ones I would consider the data to be significant. But since none of them were I actually do not know what those data mean. This is still something of a "learn as you go" type project.
