An abrupt change at White Island in the Bay of Plenty at the end of July has continued, with the volcano now producing ash for the first time in more than a decade.
A period of relative quiet at White Island has ended, with increased gas emissions, an abrupt rise in the level of the crater lake and bursts of volcanic tremor.
Low-level activity which began at Mt. Tongariro on July 13th has continued, and GNS Science has increased its monitoring of the volcano. Seismic activity and volcanic gas emissions confirm a low level of unrest.
Mt. Ruapehu’s crater lake is at its hottest temperature since 2003.
The webcam at Raoul Island is back online.
A lightning strike at Raoul Island during April damaged some of the infrastructure that GeoNet installed in May last year.
The crater lake at the central North Island volcano, Mt. Ruapehu, rose slightly on Monday evening.
New Zealand’s northernmost chain of volcanoes, the Kermadec Islands, came online yesterday when GeoNet added a new seismograph and webcam to their website.
A recent eruption at an undersea volcano on the Kermadec Ridge has caused the crater to be filled with debris and reduced the summit of Rumble III volcano by 100 metres.
People interested in activity at Taupo volcano are in for a bit of a feast at the moment. GeoNet has released an article describing their monitoring at the massive caldera volcano, and Radio New Zealand National is featuring Taupo in this week’s edition of “Earthworks”.
Declining earthquake activity at Mt. Ngauruhoe has caused GNS Science to reduce the volcano’s alert status.
The crater lake at White Island is refilling, with the water temperature remaining hot while steam, gas and mud emissions from the largest nearby vent increase.
