Which of the following natural disasters happening in Indonesia is related to the fault movement of plate tectonics?

What natural disasters are caused by plate tectonics?

While the movement of tectonic plates is usually slow—typically just a few centimeters per year—plate tectonics are linked to several kinds of natural disasters, namely earthquakes, volcanoes, and tsunamis.

What tectonic plates caused the Indonesian earthquake 2018?

The January 15 event was a shallow crustal earthquake at the boundary between the Sunda plate and the Banda Sea microplate at a focal depth of 18 km. The earthquake occurred along the Mamuju–Majene thrust fault, which is known to be an active seismic source that has caused several deadly earthquakes in the recent past.

How many natural disasters have happened in Indonesia?

Indonesia lies on the Pacific “Ring of Fire” where volcanic eruptions, earthquakes, tsunamis, floods, landslides, drought, and forest fires frequently happen. With at least 1.5 thousand natural disasters occurring in Indonesia every year, the archipelagic country has one of the highest natural disaster rates worldwide.

What type of fault is Indonesia?

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.

Why does Indonesia have so many natural disasters?

Environmental disasters are not unusual for Indonesia, with the country recording a total of 2,291 disasters in 2020. The archipelago also sits on the Pacific Ring of Fire, where tectonic plates collide, causing frequent volcanic activity as well as earthquakes.

What natural disasters occur on fault lines?

Most earthquakes occur as the result of the sudden movement along a fault line between two adjacent tectonic plates. The movement of the plates is not always smooth. The plates “catch” on each other due to friction. Since the plates are always moving, these catches cause energy to build up along the fault line.

Which natural disaster is caused by shift in tectonic plates Mcq?

Most tsunamis, about 80 percent, happen within the Pacific Ocean’s Ring of Fire, a geologically active area where tectonic shifts make volcanoes and earthquakes common.
