The last M7.5+ earthquake along the Alpine Fault was 170 years ago; studies of the faults' strain accumulation suggest that similar events are likely to occur again.North of New Zealand, the Australia-Pacific boundary stretches east of Tonga and Fiji to 250 km south of Samoa. During the 2019 North Maluku earthquake, severe damage occurred in Halmahera, like collapsed buildings and cracked roads. The epicenter was located 34 km (21 miles) NNE of Ndoi Island and 335 km (208 miles) SE of Levuka, Fiji. The overall subduction velocity of the Pacific plate is the vector sum of Australia-Pacific velocity and back arc spreading velocity: thus it increases northward along the Kermadec trench from 70 to 100 mm/yr, and along the Tonga trench from 150 to 240 mm/yr.The Kermadec-Tonga subduction zone generates many large earthquakes on the interface between the descending Pacific and overriding Australia plates, within the two plates themselves and, less frequently, near the outer rise of the Pacific plate east of the trench.

On September 29, 2009, one of the largest normal fault (outer rise) earthquakes ever recorded (M8.1) occurred south of Samoa, 40 km east of the Tonga trench, generating a tsunami that killed at least 180 people.Across the North Fiji Basin and to the west of the Vanuatu Islands, the Australia plate again subducts eastwards beneath the Pacific, at the North New Hebrides trench.
Officials warned people to avoid the lower part of the mountain as...New activity/unrest was reported for 1 volcano from September 8 to 14, 2020.
According to the...Tropical Storm "Teddy" formed at 09:00 UTC on September 14, 2020, as the earliest 19th Atlantic named storm on record. Heavy ashfall was reported...Tropical Storm "Beta" is slowly moving WNW toward Texas, producing a long-duration rainfall event from the middle Texas coast to southern Louisiana. Heavy rains began around September 8, leading to inundations that disrupted traffic and trapped a number of people in a collapsed building. 2019-07-30 08:34:15 UTC 4.5 magnitude, 583 km depth Levuka, Eastern, Fiji 4.5 magnitude earthquake 2019-07-30 08:34:15 UTC at 08:34 July 30, 2019 UTC WELLINGTON, New Zealand -- A deep, undersea earthquake with a preliminary magnitude of 8.2 has struck Fiji and small tsunami waves have been observed but no damage reported. This is the 22nd named storm of the 2020 Atlantic hurricane season and the earliest named 22nd Atlantic storm, breaking the previous record set by Wilma on...5 homes were destroyed and 67 damaged after a powerful tornado ripped through Nicaragua's capital Managua on Thursday, September 17, 2020. It is likely that the first event triggered the second of the so-called earthquake "doublet". This is the 23rd named storm of the 2020 Atlantic hurricane season and the 10th so far this month -- a record for September. A magnitude 6.7 earthquake was reported Sunday morning at 8:54 a.m. Pacific time 25 miles from Ndoi Island, Fiji, according to the U.S. Geological Survey. A HUGE earthquake has struck off the coast of Fiji.
The previous record for the 19th named storm was October 4 (2005) -- this was initially an unnamed storm, added in post-season...A powerful autumn storm named Aila swept through Finland's central and southwestern regions late Wednesday into Thursday, September 16 to 17, 2020, bringing winds of up to 125 km/h (77 mph), high waves up to 5.8 m (19 feet), and heavy rains up to 60 mm (2.3...A new study has identified a major mass extinction 233 million years ago, which triggered the dawn of dinosaurs-- the event has been called the Carnian Pluvial Episode.
The spreading rate in the Havre trough, west of the Kermadec trench, increases northward from 8 to 20 mm/yr. It includes an oceanic transform (the Macquarie Ridge), two oppositely verging subduction zones (Puysegur and Hikurangi), and a transpressive continental transform, the Alpine Fault through South Island, New Zealand.Since 1900 there have been 15 M7.5+ earthquakes recorded near New Zealand. Wide swaths of crops were inundated and hundreds of houses...The first medicane of the 2020/21 Mediterranean medicane season -- named Cassilda by the unofficial Mediterranean Cyclone Center (MCC), and Ianos by the National Observatory of Athens -- formed in the Ionian Sea on September 16. At the northern end of the Tonga trench, the boundary curves sharply westward and changes along a 700 km-long segment from trench-normal subduction, to oblique subduction, to a left lateral transform-like structure.Australia-Pacific convergence rates increase northward from 60 mm/yr at the southern Kermadec trench to 90 mm/yr at the northern Tonga trench; however, significant back arc extension (or equivalently, slab rollback) causes the consumption rate of subducting Pacific lithosphere to be much faster.
Since 1900, 40 M7.5+ earthquakes have been recorded, mostly north of 30°S.
The largest recorded earthquake in New Zealand itself was the 1931 M7.8 Hawke's Bay earthquake, which killed 256 people.
