Скачать или смотреть Cascadia Tremor update.. New Zealand Deep earthquakes-Hikurangi Subduction. Sunday night 1/22/2023

The Hikurangi Subduction Zone is an active subduction zone extending off the east coast of New Zealand's North Island, where the Pacific and Australian plates collide.The subduction zone where the Pacific Plate goes under the Kermadec Plate offshore of Gisborne accommodates approximately 6 cm (2.4 in)/yr of plate movement while off the Wairarapa shore this decreases to perhaps as low as 2 cm (0.79 in)/yr. It is the southern portion of the Tonga–Kermadec–Hikurangi subduction zone and its main feature is the Hikurangi Trench. The tectonics of this area can be most easily resolved by postulating between the Havre Trough to the east of the South Kermadec Ridge Seamounts, the Whakatane graben and the Taupo Volcanic Zone on the North Island of New Zealand there is a continuation of the Tonga micro-plate into the Kermadec microplate which probably extends to Cook Strait.The on land active fault systems would be consistent with the Kermadec Plate's unclear south eastern boundary being the North Island Fault System. The Kermadec Plate - Pacific Plate western boundary is the Hikurangi-Kermadec trench.

Earthquakes
Earthquakes of up to 8.2M have been recorded on the Hikurangi Margin, generating local tsunamis, and earthquakes in the 9.0M range are thought to be possible.[4] The Ruatoria debris avalanche originated on the north part of the subduction zone and probably occurred around 170,000 years ago.[5] Multiple uplift earthquakes will have occurred in the locked areas of the fault but a good historical record does not yet exist.
