Seismic shockwaves after a meteorite’s collision could affect systems all over the planet.
Research suggests a new threat to life on Earth from the meteorite's crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet's history.
Just a burp, or indication of coming disaster?

How do scientists predict volcanic eruptions? To do so with accuracy, they need to know the individual volcano and its history very well.
Water mass enters the ocean from glaciers such as this along the Greenland coast.
Greenland's ice is largely responsible for the accelerating pace of sea-level rise. A new analysis shows that, while Greenland accounted for just 5% of the rise in 1993, that figure rose to 25% by 2014.
OK, but which sea’s level? And how do you know what it is?
The tides come in, the tides come out. But what is a sea's level? Technology has evolved since we first started gauging the height of the ocean in comparison to the land.
