Scientists monitoring the currently restless Gaua volcano in Vanuatu are relying on just one polyseismograph, leading a local seismologist to warn that insufficient monitoring is putting lives at risk:
We need back up for seismic monitoring because for the time being we have just one polyseismograph but we really need back up of two or three extra seismographs in order to locate the events.
The volcano remains on level one of the five-level alert system (where five is the highest level). Meanwhile, large earthquakes north-west of Vanuatu have shaken the area up, but with no tsunami or serious damage or loss of life. These were tectonic quakes which have no relation to the volcanic activity in Vanuatu, except in so far as both are products of subduction zone processes.
