Kilauea is a volcano shield situated on the sudant of the island of Hawaii. It is not the only volcano of the island, indeed, it is same most recent, the island of the Hawaiian Islands formed from 5 volcanoes: Kohala which is now switched off, Mauna Kea Et Hualalai which(who) are put to sleep and finally the one who interests us, Kilauea, which is active and moreover one of the most active of the world. The summit of Kilauea peaks in 1247m over the sea level, it is far from being the highest volcano of Hawaii, when we know which son brother le Mauna Kea achieves 4205m of height. I told you he(it) ya a few moments that Kilauea is a part of the most active volcanoes of the world, for a very good reason, the volcano is in quasi-permanent eruption for 30 years. So that you aillez an idea, since 1983, The volcano cross-posted more than 100 km ² of lava. Thus needs to know that Paris a 105,4 km surface ² it is rather not bad. In spite of an almost permanent eruption, Kilauea made very few victims car it is what we call a volcano shield, that is a big volcano with flat slopes, what does that the lava passes by slowly and thus quickly hardens.Well, it is very beautiful to speak about Kilauea, more it is someone he(it) knows how formed? I yes! It is very simple, Kilauea formed from a hot spot(major issue). You wonder certainly it is that is a point? A hot spot(major issue) forms from big extremely hot rocks resulting(coming) from the base(basis) of the coat, these rocks go back up(raise) what pulls(entails) a decrease of the exercised pressure, they liquefy and are transformed into magma. This magma is less dense than the rocks of the coat, goes back up(raises) up to the earth's crust and pierces her(it). Roughly, a hot spot(major issue), it is a continuous source(spring) of magma resulting(coming) from the coat.ATTENTION THE COAT IS NOT ESTABLISHED(CONSTITUTED) BY MAGMA!
Well OK, the magma pierces the earth's crust and then? Bah then, the magma ' Infiltrates in the sea. In the contact of the water, the magma hardens, trains(forms) rocks, which is going to pull(entail) the creation of a volcano of hot spot(major issue). However, Kilauea is not the only volcano trained(formed) in this way, in fact it is the archipelago of the Hawaiian Islands which(who) developed like that, looked this animation.

You see in the center of the training(formation) of a volcano of hot spot(major issue), except that this volcano moves. In fact, this phenomenon is possible thanks to the oceanic ridge which you see to the right.An oceanic ridge, it is the weakness(fault) which spews lava, which is the contact of the water, becomes of the rock and establishes(constitutes) the oceanic crust, this crust to the files(cases) of time(weather) and of the space, Other one of the ridge to make way for the new rocks, what explains the volcano of hot spot(major issue) moves. But that it pass he(it) when the volcano is not any more in the alignment of the hot spot(major issue)? Bah the volcano does not have a source(spring) anymore of magma, it is so much amazed that Kohala, is it falls asleep as Mauna Kea. As for the hot spot(major issue), he(it) is going to create a new volcano, to feed him(it), then the crust is going to spread(widen) and to move the volcano etc.An oceanic ridge, it is the weakness(fault) which spews lava, which is the contact of the water, becomes of the rock and establishes(constitutes) the oceanic crust, this crust to the files(cases) of time(weather) and of the space, Other one of the ridge to make way for the new rocks, what explains the volcano of hot spot(major issue) moves.

Kilauea it is:
-1247m of height
30 years of continuous eruption
100 km ² of cross-posted(poured) lava, 1430 km ² of surface what amounts to almost 14 % of the island of Hawaii
Here is for this volcano, I hope to have you information on things! You can react in comments if you wish, I hurry to draft other articles for you can read them!
