Tsunami Activity in Indonesia

Tsunamis destroy lives, landscapes, and alter the people's lifestyle permanently.

 

In 2004, Sumatra was the home to an extremely devastating tsunami disaster. This tidal wave caused more than 200,000 deaths. Indonesia is highly susceptible to tsunamis because of how the tectonic plates are situated. The plate boundaries are constantly shifting and moving on the seafloor, causing disruptions in the level of water on the seafloor. During a earthquake on the seafloor, the tectonic plate will uplift, causing a hortizontal reaction bringing water toward the shore.

It is very hard to predict when a tsunami will occur, but the National Tsunami Association recommends that when the ground is shaking, relocate to higher ground. Also, when sea life is exposed, (like fish) that is when a tsunami is going to hit.

Volcano Week!

Indonesia's is a volcanic hotspot due to it's geographical location on the four subducting tectonic plates , which is part of the Pacific Ring of Fire. The main volcano type present here  is a stratavolcano. This type of volcano has steeper sides, and spews out low viscosity magma, toxic gages, and rhyolite rock into the air, and billows up into a large toxic cloud.

Above is an example of a stratavolcano in Indonesia, notice how steep the sides of the volcano are.

 

Some of the most catastrophic explosions took place on islands in Indonesia. In 1815, Mount Tambora erupted in violent events which was one of the most extreme eruptions in recorded history. As the ash was spewed into the air, the average world temperature dropped about 3 degrees.

 

 

 

There are 76 active volcanoes currently in Indonesia, although there is not enough technology to state exactly when a volcano erupts, there is always preparation. Each province has their own preparedness agency, although their readiness varies. In February alone, two volcanic eruptions left about 130,000 displaced, and many dead. The National Disaster Preparedness agency works with local community governments to plan out risk mapping, identifying threats, and training officials to be ready for these disasters also.
