Massive earthquake hits Taiwan


Why is it in the news?

  • Nine people died and over 800 were injured in Taiwan’s largest earthquake in 25 years, registering 7.2 magnitude according to local authorities and 7.4 magnitude by the United States Geological Survey (USGS).
  • Taiwan is prone to earthquakes due to the interactions between the Philippine Sea Plate and the Eurasian Plate. These interactions cause frequent seismic activity in the region.
About Ring of Fire

路聽聽聽聽聽聽 The Ring of Fire is a horseshoe-shaped area comprising hundreds of volcanoes and earthquake sites that encircle the Pacific Ocean.

路聽聽聽聽聽聽 It stretches approximately 40,250 kilometres and runs through 15 countries, including the USA, Indonesia, Mexico, Japan, Canada, and the Philippines.

路聽聽聽聽聽聽 The Ring of Fire marks the meeting points of several tectonic plates, including the Eurasian, North American, Juan de Fuca, Cocos, and Philippine plates, among others.

路聽聽聽聽聽聽 The large Pacific Plate encompasses these smaller plates, leading to interactions such as sliding past, colliding into, or moving above or below each other.

路聽聽聽聽聽聽 Earthquakes occur due to the rough edges of these plates getting stuck with one another while the rest of the plate keeps moving. When the stuck edges finally unstick on one of the faults, an earthquake happens.

About Volcanic activity

路聽聽聽聽聽聽 Many volcanoes in the Ring of Fire are formed through a process called subduction, where one tectonic plate is shoved under another.

路聽聽聽聽聽聽 This process occurs when two plates collide, with the heavier plate being forced beneath the lighter plate, creating deep trenches.

路聽聽聽聽聽聽 The subduction process leads to the heating up of the oceanic plate, mixing volatile elements, and producing magma. This magma then rises to the surface, forming volcanoes.

路聽聽聽聽聽聽 Most subduction zones on Earth are located within the Ring of Fire, which explains why it hosts a large number of volcanoes.

路聽聽聽聽聽聽 The collision and subduction of tectonic plates in this region create the ideal conditions for volcanic activity.
