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 [bbc.co.uk] 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. The findings appear in the journal Science [sciencemag.org] [DOI: 10.1126/science.aaf7573] [DX [doi.org]].
