FAQ: What Tectonic Plate Is Indonesia On?

What type of tectonic plate is Indonesia on?

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.

What type of convergent plate boundary is the Indonesian island?

Indonesian archipelago was formed due to convergence between Sunda oceanic plate (part of the Eurasian plate) and Indo-Australian plate whereas Philippine archipelago was formed due to convergence between Sunda oceanic plate and Philippine Sea plate. In ocean-ocean convergence, two oceanic plates converge or collide.

What type of plate boundary is Bali on?

Block-diagram showing a cross-section of the subduction zone beneath the islands of Java, Bali, Lombok and Sumbawa in Indonesia. The Indo-Australian tectonic plate (on the left) dives under the Eurasian plate (on the right).

What plate boundary is Java Indonesia on?

This earthquake occurred along the Java-Sumatra subduction zone, where the Australian tectonic plate moves underneath Indonesia’s Sunda plate.

Why is Indonesia so volcanically active?

The geography of Indonesia is dominated by volcanoes that are formed due to subduction zones between the Eurasian plate and the Indo-Australian plate. The latter group is in one volcanic arc together with the Philippine volcanoes. The most active volcano is Mount Merapi on Java.

What direction is the Sunda Plate moving?

The Sunda Plate moves in a general Eastward direction, at a rate of 6 ± 1 mm/y at its southernmost boundary, and moves at a rate of 10± 1 mm/y at its northern boundary (Simons, 2007).

Which is the best example of a convergent plate boundary?

Answer: The Washington-Oregon coastline of the United States is an example of this type of convergent plate boundary. Here the Juan de Fuca oceanic plate is subducting beneath the westward-moving North American continental plate. The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate.

What are three types of convergent boundaries answers?

There are three types of convergent boundaries: Oceanic-Continental Convergence. Oceanic-Oceanic Convergence. Continental-Continental Convergence.

What landforms are created by convergent boundaries?

Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.

Why do earthquakes occur in Indonesia?

Earthquakes form a constant threat in Indonesia due to the meeting of major tectonic plates and volcanic activity in the region. However, scientists do not know when, or where, this next big earthquake will happen.

How often do earthquakes occur in Indonesia?

Earthquakes with a magnitude of 5.0 or lower occur almost daily in Indonesia, while more major earthquakes have occurred about once a year throughout the nation’s history. These earthquakes often trigger tsunamis or floods that devastate communities.

Can divergent boundaries cause volcanoes?

Most volcanoes form at the boundaries of Earth’s tectonic plates. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries. Divergent Plate Boundaries. At a divergent boundary, tectonic plates move apart from one another.

Is San Andreas Fault a plate boundary?

The San Andreas Fault is part of a transform plate boundary that disrupts the topography of an ancient subduction zone. The transform plate boundary is a broad zone forming as the Pacific Plate slides northwestward past the North American Plate.

Is Indonesia on a convergent boundary?

The movement forms three types of tectonic boundaries which affect Indonesia which are convergent plates which move into each other, divergent plates which move apart and transform plates which slide past each other horizontally.

How Indonesia is formed?

The Indonesian archipel- ago formed over the past 300 million years by reassembly of fragments rifted from the Gondwana supercontinent that arrived at the Eurasian subduction margin. The present-day geology of Indonesia is broadly the result of Cenozoic subduction and collision at this margin.
