However, in the case of the Tonga eruption, preliminary satellite measurements indicated that the amount of sulphur dioxide released would have only a minor impact.<\/p>\n\n\n\n<p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\">It is one of the massive explosions that the volcano can produce roughly once every 1000 years.&nbsp;<strong>One of the reasons for it being highly explosive is the Fuel-Coolant interaction.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-verse\" style=\"font-size: 18px; text-align: justify;\">When magma slowly rises into seawater, a thin film of steam forms between the magma and the water. It acts as an insulator, allowing the magma&#8217;s outer surface to cool. But this process doesn&#8217;t work when magma is blasted out of the ground full of volcanic gas. When magma enters the water&nbsp;<strong>quickly<\/strong>, any insulation layers get disrupted, exposing hot magma to cold water. It is referred to by scientists as&nbsp;<strong>&#8220;fuel-coolant interaction<\/strong>,&#8221; similar to weapons-grade chemical explosions. The magma is ripped apart by powerful blasts. A chain reaction begins, with new magma fragments exposing new interior surfaces to water, and the explosions continue, eventually jetting out volcanic particles and causing supersonic blasts.<\/p>\n\n\n\n<div style=\"height:14px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube
