Drone testing to continue at White Island

GNS Science plans to continue using a drone to gather water samples from White Island's crater Lake when necessary.

Scientists have been using a drone for several years to make flyovers of the Volcano.

Lately they've tried attaching a water bottle to a long string which the drone then lowers into the lake to collect a sample.

It avoids putting staff at risk when the area's unsafe to go near.

Volcanologist Brad Scott says as it works they'll keep on doing it.

He says recent monitoring has shown White Island continues to be in a state of unrest but it's not concerning.

The volcanic alert level was raised several weeks ago when there was a big increase in the amount of sulphur dioxide gas being emitted.

The level was lowered again when the volcano settled down.

Brad Scott says that's still the situation.
