The Australian plate is a major tectonic plate in the eastern and, largely, southern hemispheres. Originally a part of the ancient continent of Gondwana, Australia remained connected to India and Antarctica until approximately 100 million years ago when …

2024年6月22日 · The Pacific Plate is converging with the Indo-Australian Plate in the south-west, subducting under it north of New Zealand and forming the Tonga Trench and the Kermadec Trench.

2024年6月25日 · The boundary between the Australian and Pacific plates is known as the Hikurangi tectonic plate boundary. This boundary is classified as a convergent boundary, which means that the two plates are pushing against each other.

Rates of motions of the major plates range from less than 1 cm/y to over 10 cm/y. The Pacific Plate is the fastest, followed by the Australian and Nazca Plates. The North American Plate is one of the slowest, averaging around 1 cm/y in the south up to almost 4 cm/y in the north.

2016年3月20日 · The island archipelago of Tonga sits at the junction of two major tectonic plates – the Indo-Australian plate in the west and the Pacific Plate in the east. It is part of the Pacific “Ring of Fire” that encircles the entire ocean basin.

The Indo-Australian plate is or was a major tectonic plate. It is in the process of separation into three plates, and may be currently separated into more than one plate.

The Indo-Australian Plate is one of the major tectonic plates on Earth, encompassing a vast region that includes the Indian subcontinent, Australia, and parts of the Indian and Pacific Oceans.

In the south-west, the Pacific plate has a complex but generally convergent boundary with the Indo-Australian plate, subducting under it north of New Zealand forming the Tonga Trench and the Kermadec Trench.

The boundary between the Pacific Plate and Australian Plate is marked by volcanism, earthquakes, and different and unique topography. The border of these two plates is composed of a mix of transform and convergent boundaries along the Eastern edge of the Australian plate, with both divergent and convergent boundaries along the Northern edge.

2017年4月25日 · In the southwest, the Pacific Plate has a mutually subducting relationship with the Indo-Australian Plate. Forming a mostly convergent boundary, it subducts under the other, just north of New Zealand, forming underwater trenches.
