Plate Boundaries of Indonesia

 Indonesia is located on the western side of the ring of fire and is home to 4 plate boundaries. The surrounding plates include the Eurasian, Australian, Philippine, and the Pacific plates. The Convergent plate boundaries run south under Sumatra and Java in the west, through the middle of the archipelago, and along the north of West Papua New Guinea to the east. 

 

 In the west where the Eurasian and Australian plates meet is a subduction plate boundary, the Australian plate sides beneath the Eurasian plate at the Sunda/Java trench. On the eastern side of Indonesia within the intersection of the Australian, Eurasian, and Philippine plates, the convergence is divided within an belt of microplates (a small tectonic plate or plates that exist within a larger tectonic plates boundaries). The microplates create various types of faults including arc-continent collision, subduction, strike-slip, thrust, and extensional faulting. These faults are very active and the Indonesian region and it's neighboring countries experience frequent earthquakes and are prone to earthquake related hazards such as tsunamis and landslides.

    Hi Jasmine, it’s been interesting learning a bit more about Indonesia. Just like Switzerland which is the country I chose it is also prone to earthquakes.

    Hi Jasmine just like Indonesia, the Philippines (the country I chose) is also on the Ring of Fire, where several plates like the Eurasian, Philippine Sea, and Pacific plates interact. Its interesting to know that the Australian plates slide under the Eurasion plate at the sunda trench, it must cause a lot of volcanic eruptions.

Indonesia

Jakarta, capital of Indonesia Indonesia is located in the Indian and Pacific oceans off the coast of southeast Asia. It is referred to as a archipelago and consists of 17,500 islands, 7,000 of those islands are uninhabited. It is the  largest country in southeast Asia, sharing borders  with  Malaysia and Papua New Guinea.  Flag of Indonesia The islands of Indonesia have a diverse environment ranging from forested volcanic mountains, costal plains, alluvial swamps, shallow seas and coral reefs, it surrounds the intersection of three pieces of the earths crust. Holding a estimated population of 284,698,000 people, Indonesia is the fourth most populated country in the world.    The difference between hazards, disasters, and catastrophes:   Hazards are a natural process or event that is a possible threat to human life and property Disasters are a hazardous event that occurs over a limited time span in a defined area, where one of the following occurs,...

Volcanoes

Indonesia is home to about 150 volcanoes, 130 of them are active. These volcanoes sit within the ring of fire and have "high eruptive potential" due to the seismic activity of plate boundaries, such as the Indo-Australian and Eurasian plates.  The frequent earthquakes Indonesia experiences contribute to the elevated volcanic activity, not only that but the intensity of the earthquake can effect the viscosity of magma and the eruption type. Eruption patterns can be thrown off after earthquakes as well, eruptions may be speed up afterwards. In Indonesia a 6.3 magnitude earthquake in 2001 caused fumarole temperatures to rise in Mount Merapi. Mount Merapi is the most active volcano in the world, it is a pyroclastic stratovolcano that sits 2986 meters above sea level. In 2006 another earthquake resulted in the increase of magma extrusion and pyroclastic flow.  Mitigation:  In Indonesia 70% of the population is located within a volcanic zone, with some citizens living within 6 ...
