Deep 6.7 magnitude earthquake hits Tonga trench in the Pacific
ExtinctionProtocol/A 6.7
magnitude earthquake struck the Tonga Trench at a depth of 129.4 km
(80.4 miles). The earthquake was too deep to generate a tsunami. The
epicenter of the undersea quake was 2266 km (1408 miles) NNE of
Auckland, New Zealand. The Tonga Trench is a convergent plate boundary
in the South Pacific. The trench lies at the northern end of the
Kermadec-Tonga Subduction Zone, an active subduction zone where the
Pacific Plate is being subducted below the Tonga Plate and the
Indo-Australian Plate. The Tonga Trench extends north-northeast from the
Kermadec Islands north of the North Island of New Zealand. The trench
turns west north of the Tonga Plate and becomes a transform fault zone.
The Tonga Trench is one of the most seismically and
volcanically-active regions of the sea-floor on Earth. The planet’s
crust is being violently devoured at a rate of more than 24 centimeters
per year- the fastest of any region on the planet.
