The seismic network recorded two rockfalls and one volcano-tectonic earthquake this week.
Measurements of the SO2 flux were made from the helicopter on 27 and 28 March, with eight traverses on each day. The average flux was 501 tonnes per day on the 27th and 389 tonnes per day on the 28th.
Pyroclastic flows can occur at any time without warning on any side of the volcano, including Gages from where they can travel rapidly into Plymouth. Tracks across the Belham Valley can be destroyed or heavily modified by flash flooding or lahars, and caution should be exercised crossing the valley during and after rainfall.
The Hazard Level is 1. There is no public access to Zone V, including Plymouth. Maritime Zones E and W are daytime transit only between sunrise and sunset (boats may sail through the zone but must not stop). Anyone who ignores these restrictions is liable to be prosecuted.
