What happens when molten Lava meets sea water - shock wave

What happens when Lava meets ocean ?


Lava meets ocean

What is lava?

Lava is magma that scopes the surface.Magma is liquid or semi-liquid shake framed by halfway liquefying of the mantle or outside layer.

At the point when magma achieves the surface it emits as a spring of gushing lava and the magma is then named lava.

Lava hits ocean water

Lava has a slight distinction from magma in that magma has gasses that are restricted to the magma by the weight of the overlaying rock. At the point when the magma achieves the surface those gasses are discharged, the subsequent lavas have marginally unique synthetic structures due to the loss of those gasses from the magma.

Volcano eruption

Underwater volcanos commonly have lava that streams out as a fluid, rather than passing the best over and sending lava bombs, hot streams of volcanic trash down the valleys and fixing the pulverization under a layer of volcanic fiery debris.


As lava pushes out from the volcano, water weight pushes back, constraining the lava to frame a shape with the slightest surface, a round cushion molded lump. It's cool down there and the lava touching the water chills and sets into rocks.

Lava flow

For specifically lava flowing into water, the water would possibly evaporate a bit once the lava nears surface, as lava gives off an outstanding quantity of heat, being measured at upwards of 700 degrees c. Considering the fact that lava usually flows slowly, this gives a bit of time for the water to evaporate as it nears.

Lava meets sea water

Water can cool the floor of a lava go with the flow extra successfully than can air, so lava flowing in water develops a solidified skin very unexpectedly. However, when the crust reaches slight thickness, it insulates the lava go with the flow interior just as properly because it does in air.

Lava steam

Hawaii and other island volcanoesare in a steady competition for the freshest, most up-to-date rock round. Whilst the lava meets the ocean, it cools speedy while boiling the ocean into steam. This consequences in a specific texture: the quenching produces a glassy outer surface from the lava cooling too quickly for crystal shape to develop. This insulates the inner of the globs, trapping any dissolved gasoline as bubbles and permitting internal microcrystal growth from the slightly slower cooling charge.

Risky impacts :


At the point when lava cooperates with seawater an assortment of harmful gasses are created, including hydrochloric corrosive, which is very destructive. The lava cloudiness, or laze, as it is called, can be misleadingly fatal. It would appear that a pretty white steam cloud leaving the water, yet it's most certainly not. It's corrosive! This may bring about swelling of lungs or other issue identified with lungs because of HCl inward breath and propelled disintegration of skin when presented to these vapors.


In the event that temperature of lava is adequate sufficiently high to dissipate water at that point steam will be watched ascending from the sea surface 0.5 - 5 kms seaward, with many fish murdered in the region. Within the sight of harmful gasses like SO2, nitric oxides, and so forth discharged after blending with water, steam mists blend with them and can hasten Acid Rain which is perilous to close-by life.
