The convergence is taking place at a rate estimated at approximately 15 centimetres (6in) per year (by Lonsdale, 1986); however, recent Global Positioning Satellite measurements indicate in places a convergence of 24 centimetres (9in) per year across the northern Tonga Trench, which is the fastest plate velocity recorded on the planet; a result is the earth's most active zone of mantle seismicity.
While most of the large earthquakes occur at the contact zone between both tectonic plates, related to the friction during subduction, others are produced in the Pacific plate due to its bending.
Tonga ([ˈtoŋa]; Tongan: Puleʻanga Fakatuʻi ʻo Tonga), officially the Kingdom of Tonga, is a Polynesian sovereign state and archipelago comprising 177 islands of which 52 islands are inhabited. The total surface area is about 750 square kilometres (290sqmi) scattered over 700,000 square kilometres (270,000sqmi) of the southern Pacific Ocean. It has a population 103,000 people of whom 70% reside on the main island of Tongatapu.
Tonga became known as the Friendly Islands because of the congenial reception accorded to Captain James Cook on his first visit in 1773. He arrived at the time of the ʻinasi festival, the yearly donation of the First Fruits to the Tuʻi Tonga (the islands' paramount chief) and so received an invitation to the festivities. According to the writer William Mariner, the chiefs wanted to kill Cook during the gathering but could not agree on a plan.
Tonga's population is 358, making it the seventh most populous village in Tuvalu. It is the main village of the island of Nanumanga, comprising 52% of the population of the island. The only other village is on the island Tokelau.

Fly Through: Tonga Trench
As part of the Five Deeps Expedition in 2019, our team mapped the second deepest place in the ocean – Horizon Deep, Tonga Trench in the southern Pacific Ocean. Over a couple weeks, the team collected more than 13,000 km2 of bathymetry essential for identifying the deepest point of 10,820 m, dive planning, and scientific exploration. The expedition sent Victor Vescovo down to the bottom to explore.

The Deepest Points in Each Ocean
What's the deepest place on Earth? Most of us would name the Mariana Trench and not without reason. It's the very place in the ocean that hides so many secrets and bizarre creatures. But what if it's not the deepest point... Let's cruise through the deepest places on our planet. What mysteries are they hiding?

Between the continental margin and the oceanic ridge lies the deep ocean basin. The size of this region, almost 30% of earth's surface, is roughly comparable to the percentage of land above sea level. This region includes:
1) extremely deep linear depressions in the ocean floor called deep ocean trenches;
2) remarkably flat areas known as abyssal plains;
3) tall volcanic peaks called seamounts and guyots; and

A New Time-lapse of an Island Forming in Tonga
Hunga Tonga-Hunga Ha'apai is the first island of this type to erupt and persist in the modern satellite era, it gives scientists an unprecedented view from space of its early life and evolution. The new study offers insight into its longevity and the erosion that shapes new islands. Understanding these processes could also provide insights into similar features in other parts of the solar system, including Mars.

5.4 How deep are ocean trenches such as the Mariana Trench and the Tonga Trench?
Between the continental margin and the oceanic ridge lies the deep ocean basin. The size of this region, almost 30% of earth's surface, is roughly comparable to the percentage of land above sea level. This region includes:
1) extremely deep linear depressions in the ocean floor called deep ocean trenches;
2) remarkably flat areas known as abyssal plains;
3) tall volcanic peaks called seamounts and guyots; and
4) large sediment filled and flood basalt provinces called oceanic plateaus.
Deep ocean trenches
Deep ocean trenches are long, relatively narrow creases in the seafloor that form the deepest parts of the ocean. Most trenches are located along the margins of the Pacific Ocean, where many exceed 30,000 ft in depth. A portion of one trench, the Challenger Deep In the Mariana Trench, has been measured at 36,163 ft below sea level making it the deepest known part of the world ocean. The Tonga Trench is over 35,000 feet deep. Only two trenches are located in the Atlantic Ocean, the Puerto Rico trench adjacent to the Lesser Antilles Arc, and the South Sandwich Trench, both in excess of 25,000 feet deep.
Although deep ocean trenches represent only a small portion of the area of the ocean floor, they are nevertheless significant geologic features. Trenches are sites of plate convergence where lithospheric plates subduct and plunge back into the mantle. In addition to earthquakes being created as one plate “scrapes” against another, volcanic activity is also associated with these regions. The trenches are often paralleled by an arc-shaped row of active volcanoes called a volcanic island arc. Furthermore, continental volcanic arcs, such as those making up portions of the Andes and Cascades, are located parallel to trenches that lie adjacent to continental margins. The large number of trenches and associated volcanic activity along the margins of the Pacific Ocean explains why the region is known as the Ring of Fire.
Abyssal Plains
Abyssal plains are deep, incredibly flat features. In fact, these regions are likely the most level places on Earth. The abyssal plain found off the coast of Argentina, for example, has less than 10 feet of relief over a distance exceeding 800 miles. The monotonous topography of abyssal plains is occasionally interrupted by the protruding summit of a partially buried volcanic peak.
Seamounts and Guyots
Dotting the ocean floor are submarine volcanoes called seamounts, which may rise hundreds of feet above the surrounding topography. It is estimated that more than a million of these features exist. Some grow large enough to become oceanic Islands but these are rare. Most do not have a sufficiently long eruption history to build a structure above sea level. Although these conical peaks are found on the floors of all the oceans, the greatest number have been identified in the Pacific. Furthermore, seamounts often form linear chains, or in some cases a more continuous volcanic ridge, not to be confused with mid-ocean ridges.
Some, like the Hawaiian Island Emperor seamount chain in the Pacific, which stretches from the Hawaiian Islands to the Aleutian Trench, form over a volcanic hotspot in association with a mantle plume. Others are born near oceanic ridges. If the volcano grows large enough before being carried from the magma source by plate movement, the structure may emerge as an island. Examples in the Atlantic include the Azores, Ascencion, Tristan da Cunha, and Saint Helena.
Oceanic Plateaus
Mantle plumes have also generated several large oceanic plateaus, which resemble the flood basalt provinces found on the continents. Examples of these extensive volcanic structures include the Ontong Java plateau and the Caribbean plateau, which formed from vast outpourings of fluid basaltic lavas onto the ocean floor. Hence, oceanic plateaus are composed mostly of basalts and ultramafic rocks that in some cases exceed 15 miles in thickness.

The convergence is taking place at a rate estimated at approximately 15 centimetres (6in) per year (by Lonsdale, 1986); however, recent Global Positioning Satellite measurements indicate in places a convergence of 24 centimetres (9in) per year across the northern Tonga Trench, which is the fastest plate velocity recorded on the planet; a result is the earth's most active zone of mantle seismicity.
While most of the large earthquakes occur at the contact zone between both tectonic plates, related to the friction during subduction, others are produced in the Pacific plate due to its bending.
