How do the numbers of active volcanoes in the Pacific Ocean and Atlantic Ocean compare

There are many volcanoes in the world, in the past 400 years, the outbreak of more than 500 active volcanoes. Although the number of volcanoes, but its distribution is very regular. Volcanoes are divided into four zones: the Pacific-Pacific volcanic belt, the Atlantic volcanic belt, the Mediterranean volcanic belt and the East African volcanic belt. Pacific volcanic belt, including east and west sides, like China's Taiwan in this volcanic belt. Known as the "volcano of the country," El Salvador is also in this volcanic belt, the world's highest active volcano - Chile's Yuyaja volcano, 6723 meters above sea level; the highest extinct volcano - Chile Aconcagua volcano, 6964 M, also in this belt. The most striking submarine volcanic eruptions in the Atlantic volcanic belt and the subsequent formation of volcanic islands. There, sometimes you will see the strange phenomenon of submarine volcanic eruptions, a few days time, the original piece of ocean can emerge an island. As the newly formed volcanic island material is relatively loose, unable to withstand the impact of waves, so often as magic and suddenly disappeared. The volcanic belt of the Mediterranean is known for its volcanic activity, and the world-famous Vesuvius is on this volcanic belt. Many of the volcanoes on this belt are still active, such as Mount Etna on Sicily, which has never ceased to erupt from 6,000 BC to today. The continent is subject to both sides of the pull force and the formation of faults, called the East African Great Rift Valley, where volcanic activity is very active. Rift Valley on both sides, stands a volcano, extinct volcanoes are still water vapor, hot springs, active volcano is steaming, smoke-filled. Two world-famous volcanic wonders are here: one is the second largest caldera - Ngorongoro crater, one is the lava lake of Nyragongo volcano. Africa's first peak - Mount Kilimanjaro, the second peak - Mount Kenya, these two extinct volcano peak covered with snow throughout the year, very beautiful.
