How fast is the Nazca plate moving?
approximately 80 millimeters/year
Relative to a fixed South America plate, the Nazca plate moves slightly north of eastwards at a rate varying from approximately 80 millimeters/year (mm/yr) in the south, to approximately 65 mm/yr in the north.
In what location is most lithosphere destroyed?
Divergent boundary is most lithosphere is created, Convergent boundary that causes a subduction zone is where most is destroyed.
Where is the youngest ocean floor found?
Mid-Atlantic Ocean Ridge
The divergent boundaries are the areas where plates are moving apart from one another. Where plates move apart, new crustal material is formed from molten magma from below the Earth’s surface. Because of this, the youngest sea floor can be found along divergent boundaries, such as the Mid-Atlantic Ocean Ridge.
Does Nazca Plate have earthquakes?
The subduction of the Nazca plate under southern Chile has a history of producing massive earthquakes, including the largest ever recorded on earth, the moment magnitude 9.5 1960 Valdivia earthquake.
Does the Nazca Plate have volcanoes?
The Galápagos Islands are a volcanic archipelago formed by a mantle plume beneath the Nazca Plate; the plume is adjacent to the Galápagos Spreading Center (GSC). The most active volcanoes are in the west, with island emergence ages increasing eastward.
What may happen to oceanic plate as it continues to move downward?
As it continues to move downwards, it will undergo subduction process. It will melt because of the very hot or high temperature of the mantle which is the layer below the crust.
What happens when an oceanic plate meets another oceanic plate?
When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. Old, dense crust tends to be subducted back into the earth. An example of a subduction zone formed from a convergent boundary is the Chile-Peru trench.
Where is New lithosphere created?
New lithosphere is constantly being produced at the oceanic ridges. Lithosphere is consumed at the subduction zones. A balance is maintained because older, denser proportions of oceanic lithosphere descend into the mantle at a rate equal to seafloor production.
How lithosphere is destroyed?
Old oceanic lithosphere is destroyed when it subducts or dives beneath adjacent plates at subduction zones. Oceanic trenches are the topographic expression of these subduction zones. Large continental masses can shut down subduction zones when they enter them. (Like trying to flush a 50 lb.
Where did the earthquake happen in the Philippines?
At least 14 people have died after a series of earthquakes rattled the southern Philippines. A 6.5 magnitude quake struck on Thursday morning, local time, in the Tulunan area of Cotabato province on the southern island of Mindanao. That jolt came only two days after a deadly 6.6 magnitude quake.
How are earthquake intensity ratings in the Philippines?
Intensity ratings are based on the PHIVOLCS Earthquake Intensity Scale. All content is in the public domain unless otherwise stated.

When was the most recent earthquake in China?
Recent earthquake events that affected Regions XI and XII are the M5.9 on 9 July 2019, the M6.3 on 16 October 2019, the M6.6 and M6.1 on 29 October, and M6.5 on 31 October . The maximum intensity of the M6.9 event was felt at PEIS VII (see table) and shaking was felt as far as 300 kilometers away from the epicenter.
How big was the tsunami in the Philippines?
Both earthquakes triggered tsunamis, with the second being quite destructive, with a maximum run-up of 7.0 m. At least 13 died as a result of the second tsunami, with a hundred or more casualties also being reported. Large earthquakes ≥ 6.4 M w near the Manila Trench.
