At the active volcano of big island, the lava flowed from the caldera and flowed for miles to the Pacific Ocean. Due to the large amount of chemical and physical reaction of the high temperature magma into the sea, the large amount of gas in the mouth of magma is toxic and corrosive, and it often rains heavily. In order to capture the sight of the lava pouring into the sea at dusk, I walked 40 miles in two days and finally find the great position to get this picture.
