Vanuatu

This page is a closer look at the Region of Vanuatu (formerly known as the New Hebrides Islands).
Firstly a look at swarms of earthquakes in the southern region of Vanuatu mostly on the South New Hebrides Trench. Many of the larger quakes are reported as being felt in New Caledonia.

This first map shows all the earthquake swarms/aftershock series between 2000 and 2011, of which there were 6 with more than 7 events in sequence. Any earthquakes more than 2 days outside each end of sequence are not included in the data of each map/ list.
Number 1 being the oldest (2007) and 6 the most recent 20/8-9/1/2011
