Seismologists in Japan have tracked, for the first time, a particular type of tiny vibration that wobbled through the Earth from the Atlantic seafloor.
It was started by a "weather bomb": the same low-pressure storm, off Greenland, which made UK headlines in late 2014.
Tiny tremors, of two types, constantly criss-cross the deep Earth from storms.
The slowest of these, the "S" wave, has never been traced to its source before and researchers say it opens up a new way to study the Earth's hidden depths.

Signs of great changes coming upon the Earth?
