USGS site

It's not ideal, but on a computer, hovering over a dot will tell you the location without having to click on it. I don't know if that will work on a phone screen.

Hovering over a dot on a phone is worse. As mentioned a bookmarked favorites page works pretty well. The site turned goofy.

Don’t worry. It will be shut down soon and you won’t have to worry about it anymore.
