When two major earthquakes occur within days of each other thousands of kilometres apart, it can look like they’re connected. But are they? Here’s what the science says.
The earth around you might seem static but it’s constantly in motion. We need to track this motion in fine detail if we’re to keep our GPS networks up to date.
