Indonesia sits along the “Pacific Ring of Fire” where several tectonic plates collide and many volcanic eruptions and earthquakes occur. Some of these earthquakes are very large, such as the magnitude 9.1 quake off the west coast of Sumatra that generated the 2004 Indian Ocean tsunami.
Is Indonesia tectonically active?
Indonesia is a geologically complex region situated at the southeastern edge of the Eurasian continent. It is bordered by tectonically active zones characterized by intense seis- micity and volcanism resulting from subduction.
Why is Indonesia having so many earthquakes?
Indonesia is prone to earthquakes because it’s on the Ring of Fire, an arc of volcanoes and fault lines in the basin of the Pacific Ocean. … “Plate tectonics and the Ring of Fire are the main reasons why Indonesia has so many earthquakes and volcanic eruptions,” CNN meteorologist Allison Chinchar said.
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.
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.
