The lava erupting from the current Kīlauea vents has a temperature of roughly 1,150 degrees °C (2,100 degrees F), and has a journey of between 4.5km and 5.5km (2.7 to 3.4 miles) to reach the ocean. Apart from making lava look like absolutely delicious melted caramel (mmmm, caramel), they show the how rapidly magma-heated water expands into steam and the devastating eruption that occurs afterwards. What forms when lava cools underwater? Microplastics can be carried down by the settling clay, but how much this happens exactly is unknown. One of the first effects of the 1,100ºC lava hitting the ocean will be the water beginning to boil and create steam. Experts believe that mixing lava with water will result in rapid cooling of the boiling fluid . With its fairly close proximity to the sea, officials are trying to prepare for what happens then.

For specifically lava flowing into water, the water might evaporate a little once the lava nears surface, as lava gives off an impressive amount of heat, being measured at upwards of 700 degrees C. Since lava generally flows slowly, this gives a bit of time for the water to evaporate as it nears. Muddy rivers, like the Mississippi or the Amazon, contain clays that settle rapidly when they come into contact with salty ocean water.

Lava from an erupting volcano on Spain's La Palma island has reached the Atlantic Ocean, raising fears of toxic gases being released and explosions. When the lava meets the sea, it cools quickly while boiling the ocean into steam. In many volcanoes, the magma rises up through a central tube or "throat," and emerges out the top of the mountain. When magma pressure builds up enough to force its way out to the seafloor, eruption occurs. Laze is a gas plume that results from lava and ocean water contacting each other. . It erupts non-explosively and moves very quickly when it reaches Earth's surface as lava. Can Lava Reach The Ocean?

As lava reaches the coastline, an 'ocean entry' forms where lava interacts with seawater producing hydrovolcanic explosions that fragments the lava and can eject it hundreds of meters into the air. In addition, this lava-water interaction results in a plume of steam that contains volcanic gases and aerosols including hydrochloric acid. If residents keep a safe distance from the haze plumes, it shouldn't cause irritation to their eyes, lungs, or skin. The flow of lava has slowed to around 120m (400ft) an hour and was not expected to reach the Atlantic Ocean until Wednesday, according to the head of the Canary Island Volcanic Emergency Plan, Miguel Angel Morcuende.

Once the sun's energy reaches earth, it is intercepted first by the atmosphere. Eventually, the pressure from these bubbles is stronger than the surrounding solid rock, and this surrounding rock breaks, allowing the magma to rise to the surface. The new laze threat is a mix of hydrochloric acid fumes, steam and fine volcanic glass specks created when erupting lava, which can reach 2,000 degrees Fahrenheit, reacts with sea water.

During the eruption, blobs ("cinders") of lava, blown into the air, break into small fragments that fall around the opening to the volcano. In addition, this lava-water interaction results in a plume of steam that contains volcanic gases and aerosols including hydrochloric acid. Once there's enough molten rock — called magma — and enough pressure on it, a volcanic eruption occurs.
