The Pacific Ring of Fire
What is
Pacific Ring of Fire? What is in there? How volcanoes are formed? This are the
guide questions that we want to find out.
The Pacific Ring of Fire is the boundaries of the Pacific
plate where we can see many active volcanoes. The Pacific plate is the largest
tectonic plate on Earth. Almost oceanic plate, it is subducted underneath large
and small continental plates that surround it. As the edges of the Pacific
plate scrape and collide against continental plates during subduction,
volcanoes, deep ocean trenches, mountain ranges formed. Also the Pacific Ring
of Fire is susceptible to and very much frequented by volcanism-related
geological activities such as volcanic eruptions, earthquakes, faulting, and
tsunamis among others. It is where more than half of the world’s volcanoes are
found. Volcanic activity, such as eruptions and the crustal movements around
the Pacific plate, have caused massive seismic activities. There are such
happened in the Pacific Ring of Fire like eruptions of volcanoes, and followed
by several earthquakes that almost people who lived in the Pacific might
experienced. During volcanic eruptions can cause many people died and faced
different difficulties like crisis of food, things they need and others. Not only
volcanic eruptions can cause of death but also followed by an earthquake that
caused of destruction and destroyed of things and buildings that may affect the
lives of the people. Earthquake refers to the shaking of the Earth as a result
of breaking and shifting of the rocks of the tectonic plates, which release
seismic energy. Majority of earthquakes occurred along the boundaries of
tectonic plates, which collide, push each other, or slide past each other.
Earthquakes occur because of the pressure underneath the earth’s crust that
pushes blocks of rocks to move along fault lines. When we talk about the
formation of the volcano, volcanoes are formed because of the massive friction
occurred to the two massive plates that released enough energy that makes the
rocks melt. The melted rocks due of the massive friction formed into magma that
goes up to escape on the Earth surface that eventually seek a vent. Due of
continues subduction, it gives high internal heat the reason why magma push up
to reach the Earth surface. Volcanoes formed in subduction zones. In other
words, subduction happens during the subduction of the oceanic and continental
plate, the oceanic plate goes down. As the denser oceanic plate subducts
beneath the continental plate and descends into the mantle that gives
temperature increases causing the rocks to melt. The same mechanism also may
occur between two oceanic plates with different densities that the denser plate
subducts beneath the another. Such activity may result in the formation of
underwater volcanoes. The volcanic debris from the eruption of underwater
volcanoes pile up until an island volcano rises above level. In other theory,
volcanoes are formed because there are hot spots that rocks rises up causing
the formation of volcanoes.
In summary,
we know already what is the Pacific Ring of Fire, it is the boundaries of the
Pacific plate where we can see many active volcanoes and also with the
formation of the volcanoes because of subduction. In that such activities, we
should put in mind that we are also located in the Pacific ring of Fire and we
must know what to do and how to handle this. In order for us to get ready in
this earthquake activity, we should know what to do. It’s always important to
be calm and alert during an earthquake. One should know the safest spot to stay
and the easiest to escape route to minimize or avoid accidents or further
damage. That’s the relation about living in the Pacific Ring of Fire and how
volcanic activities can affect into the lives of the people.
