Answer:
Japan is situated in a volcanic zone on the Pacific Ring of Fire. Most of the earthquakes following that occurred in Japan happened because of a destructive plate boundary. This is when continental and oceanic plates collide and the heavier, more dense oceanic plate sinks underneath the continental one.
Earthquakes are most common at tectonic plate boundaries where different plates meet called fault line. They were thought to not occur anywhere but near plate boundaries.
Answer:
Stratovolcanoes
Explanation:
Stratovolcanoes are usually defined as those volcanoes that are characterized by the presence of steep slopes, having a height of about thousands of feet and comprised of alternate layers of ash deposited particles and lava flows. These are very explosive and when it comes in contact with water, it erupts violently. These are also known as composite volcanoes. It produces pyroclastic materials, along with volcanic blocks and ashes with a large amount of toxic gases.
There are 550 active volcanos in the world, almost all of which are located at convergent tectonic plate boundaries. This includes all of the volcanoes in the pacific ring fire, such as Japan's mount fuji, as well as mount saint helens, popocafepeti in mexico and Azul in the Andes range.
