How many volcanoes are there in Japan?

It is unknown because there are more than a mill on the earth under sea and on land but there is a recorded number in history of eruptions more info from random site There are probably millions of volcanoes that have been active during the whole lifespan of the earth. During the past 10,000 years, there are about 1500 volcanoes on land that are known to have have been active, while the even larger number of submarine volcanoes is unknown. At present, there are about 600 volcanoes that have had known eruptions during recorded history, while about 50-70 volcanoes are active (erupting) each year. At any given time, there is an average of about 20 volcanoes that are erupting. hope you got what look-in for <(-_-)>


Why are some volcanoes more active than others?

some volcanoes are more active than others because some volcanoes lie on plate boundaries that move frequently which adds more pressure to the magma chamber where all of the lava is stored. Other volcanoes are formed but do not gain much pressure because they have been formed slowly or have errupted many times before and do not gain any more pressure. Some volcanoes are temperarily dormant which means they are not active. Some volcanoes have been dormant for hundreds of years because there is not enough pressure for the volcano to errupt. Hot countries may have an affect or volcanoes that started off very close to the epi-center of the earth, that has lava flowing up to the volcanoes frequently from there, which may set them off more. I hope this has answered your question.
