GNS Science have requested that New Zealanders send in their observations following the Tongan eruption and tsunami.

'We are interested in your observations of the sea and coastal areas following the Hunga Tonga-Hunga Ha'apai eruption on 15 January 2022,” says a Geonet spokesperson.

'We would also like to know about ‘booming' sounds heard around the time of the eruption Saturday evening.”

A pressure surge from the latest eruption of the Hunga-Tonga-Hunga-Ha'apai volcano in Tonga was observed by New Zealand weather stations across the country.

The pressure wave from the Tongan volcano was recorded at weather stations at Cape Reinga, Auckland, Tauranga, Gisborne, Taupo and Wellington between 6.50pm - 7.45pm on Saturday January 15.

Reports of explosions were heard in New Zealand which is over 2000km from Tonga. The shock wave from the Tonga eruption rippled out at about 1000km per hour.

Many people across New Zealand reported hearing explosion and booming sounds following the eruption.

'Our researchers would love to hear from you if you noticed any unusual behaviours of the sea or coastal areas in the hours and days following the eruption, or have photos and videos of this happening,” says a Geonet spokesperson.

'We are also interested in experiences from people who heard the ‘booming' sounds that travelled around the world during the eruption.”

'The data we collect could be used in the New Zealand historical tsunami database in our write-up about these events,” says a Geonet spokesperson.

'This information can help improve tsunami forecasts and can assist in education about tsunami. Providing any personal data is optional, your data will be used for research purposes and will be kept anonymous.”
