Phreatomagmatic Eruption 4
Phreatomagmatic Eruption 4 :
Phreatomagmatic eruptions occur when magma comes into contact with water causing the water to flash to steam. The expanding steam disrupts not only the pre-existing solid rock but also the magma itself so that the fragments thrown out are a mixture of broken-up old rocks and new rocks. The products of a phreatomagmatic eruption include pyroclastic fall, flow and surge deposits. The 1979 eruption of the Soufrière of St. Vincent began as a phreatomagmatic eruption and this is also the predominant eruption style of the Kick 'em Jenny submarine volcano
