They believe variations in the speed of Earth’s rotation could trigger intense seismic activity, particularly in heavily populated tropical regions. Although such fluctuations in rotation are small – changing the length of the day by a millisecond – they could still be implicated in the release of vast amounts of underground energy, it is argued.
