What plate boundary is Sumatra Indonesia on?

Sumatra is at the boundary between two tectonic plates. The ocean floor southwest of Sumatra is part of the Indian/Australian plate, while Sumatra and the other islands of Indonesia and Thailand are part of the Eurasian plate (see Figure 1).

What type of plate boundary was the Sumatra earthquake?

The December 26, 2004 magnitude (M) 9.1 Sumatra-Andaman earthquake occurred along a tectonic subduction zone in which the India Plate, an oceanic plate, is being subducted beneath the Burma micro-plate, part of the larger Sunda plate.

Is Sumatra a convergent plate boundary?

Sumatra is one of the Sunda Islands of Indonesia and is situated near the convergent boundary where the Indian-Australian plate subducts beneath the Eurasian plate (Schlüter et al., 2002; Sendjaja et al., 2009).

What type of plate boundary is Java and Sumatra?

convergent plate boundary
Tectonic Structure of the Forearc Ridges off Sumatra, Java and the Sunda Strait. [19] Outstanding features of the convergent plate boundary along the Sunda Arc are a well structured, 120–140 km broad accretionary prism and a deep forearc basin.

Which plate boundary is destructive?

A destructive plate boundary is sometimes called a convergent or tensional plate margin. This occurs when oceanic and continental plates move together. The oceanic plate is forced under the lighter continental plate. Friction causes melting of the oceanic plate and may trigger earthquakes.

Is Indonesia on a destructive plate boundary?

Indonesia sits along the “Pacific Ring of Fire” where several tectonic plates collide and many volcanic eruptions and earthquakes occur.

What type of fault is Sumatra?

The Indonesian island of Sumatra is located in a highly seismic area of the world. In addition to the subduction zone off the west coast of the island, Sumatra also has a large strike-slip fault, the Great Sumatran Fault also known as Semangko Fault, running the entire length of the island.

What are the two types of destructive plate boundaries?

3.4 Destructive plate boundaries

• those involving the convergence of two oceanic plates (ocean-ocean subduction)
• those where an oceanic plate converges with a continental plate (ocean-continent subduction)
• collisions between two continental plates (continent-continent destructive boundaries).

Is a collision plate boundary destructive?

Destructive plate margins As the plates collide, the oceanic plate is forced beneath the continental plate. This is known as subduction . This happens because the oceanic plate is denser (heavier) than the continental plate. When the plate sinks into the mantle it melts to form magma.

What type of plate boundary is Sumatra?

With Sumatra being on the boundary of two tectonic plates it is destined to constantly be affected by Earthquakes. This subduction boundary is referred to as the Sumatran Subduction trench. Here, the oceanic Indian/Australian plate is slowly descending beneath the Eurasian plate.

What type of plate boundary is indindonesia?

Indonesia is located between two continental plates: the Eurasian Plate (Sunda Plate) and Australian Plate (Sahul Shelf); and between two oceanic plates: the Philippine Sea Plate and Pacific Plate. Beside this, what type of plate boundary is Sumatra Indonesia? Sumatra is at the boundary between two tectonic plates.

What is the Sumatran subduction trench?

With Sumatra being on the boundary of two tectonic plates it is destined to constantly be affected by Earthquakes. This subduction boundary is referred to as the Sumatran Subduction trench.

What is the Eurasian tectonic plate?

The Eurasian tectonic plate has been referred to as a bulldozer and is constantly causing trouble for Sumatra and surrounding countries. The 2004 tsunami and earthquake caused by a destructive boundary was not the only one that Sumatra has been hit with.
