The massive 8.8 earthquake that struck Chile may have changed the entire Earth's rotation and shortened the length of days on our planet, a NASA scientist said Monday.
The quake, the seventh strongest earthquake in recorded history, hit Chile Saturday and should have shortened the length of an Earth day by 1.26 milliseconds, according to research scientist Richard Gross at NASA's Jet Propulsion Laboratory in Pasadena, Calif.

Volcanic explosions expected in Chile quake's wake

Besides aftershocks, Chile's magnitude 8.8 earthquake on 27 February may also leave a legacy of volcanic explosions.

"We expect to see an upsurge in volcanic activity over the next 12 months" - David Pyle, a volcanologist at the University of Oxford.

Charles Darwin was among the first people to suggest a link between large earthquakes and increased volcanic activity. In his records, he notes that a large earthquake off Chile's coastline in February 1835 appeared to resurrect previously inactive volcanoes, and cause active ones to increase their eruption rates.
