Volcanic lava flows from Kilauea Hawaii
• The lava flows from Kilauea volcano in Hawaii
Kilauea in Hawaii (translated from Hawaiian - "belching") - one of the most active volcanoes on Earth. He continuously erupting since 1983 already.
This lava flow, called "61g", began his journey at a speed of 2 to 15 meters per hour from the Kilauea volcano in May, at the end of July it reached the water. Let us trace the entire path of lava from Kilauea Volcano in Hawaii, but at the same time see if you can stop this flow.
In my 2016 Kilauea increased pressure in the cone has reached a critical point, and burst out magma.

Speed Sometimes lava flow can reach several meters per second. But it is not in our case. lava temperature ranges from 500 to 1200 ° C.
heated up to 1000 degrees Celsius lava is moving in unpredictable directions, destroying everything around. Attempts to stop or redirect it in many respects depend on the terrain, resources and luck. Can you stop it?
Lava Tube, June 30, 2016. The lava tube - the channels, which are obtained by non-uniform cooling of the current lava down the slopes of the volcano.
But we digress. So, the idea of stopping the lava 1: bomb. In 1935, as the lava ever closer to the Hawaiian Hilo Hawaiian Volcano Observatory Director Thomas Jaggar suggested bomb lava tubes. The fact that they are helping a hot volcanic mass flow faster and further by coating the walls of the frozen lava. But craters left by the bombing, was soon again filled with lava. The town survived only thanks to the fact that the volcano stopped erupting.
Idea 2: fill with water.
In 1973, the Icelandic island of Heimaey in a few months lava flows, threatened the city Vestmannaeyjar, poured from a water jet with seawater. Getting on the red-hot magma, it evaporates, helping to solidify. One-fifth of the city was destroyed before there brought more powerful water cannons. Soon the lava was stopped, and the bay is saved. Total for this operation is 6.8 billion gallons of water were used. But it is not always possible to stop water lava: lava flowed slowly, and the amount of cooling water was almost unlimited in this particular situation.

3 The idea: to build a barrier.
In 1983 there was another eruption of Mount Etna on the east coast of Sicily, and it threatens to destroy the three cities. They were quickly erected barriers of rocks and ash. As a result, the lava has overcome one of the first barriers, 18 meters high and 10 meters wide, but the second barrier still managed to stop it. lava flow on the southern slope of the volcano Kilauea, July 25, 2016.
Idea 4: artificial canals.
10 years later again Etna eruption, this time threatening the city of Zafferana. The Italian authorities, taking into account the previous experience of the bombings launched lava, sending it into artificial channels. The rest of the stream has been allotted by concrete blocks.
The place where the lava flow, a width of about 250 meters, enters the ocean, August 5, 2016.
In general, the country needs to have sufficient financial capacity to stop the lava. It is believed that you can only delay the inevitable, if the volcano did not stop.
