7.8 earthquake triggered 'slow motion' quakes in New Zealand

A US-based study has documented the first instance of a high magnitude earthquake triggering a series of slow slip events 480 kilometres away from the epicenter. Generally, slow slip events, a type of slow motion earthquake, are thought to trigger larger earthquakes. However, a 7.8 magnitude earthquake in New Zealand in November 2016 was found to cause the slow slips.
