21. After the explosive eruption , the north side of Kobandai collapsed and sector collapses begun. 22. Additionally, at a certain threshold, fragmentation within the magma can cause an explosive eruption . 23. After an initial explosive eruption , extrusion of gas-depleted dacite magma commonly forms lava domes. 24. But the expanding lava dome and its fiery temperature don't signal an explosive eruption . 25. Subsequently, intermittent major explosive eruptions occurred, with subordinate lava flows and small pyroclastic flows. 26. Volcanic activity mostly consists of explosive eruptions and ash flows. 27. Ashfall produced by explosive eruptions could interfere with air traffic. 28. The eruption was from a flank vent and involved lava flows and explosive eruptions . 29. Part of the Auckland volcanic field, it was created by a series of explosive eruptions . 30. The inclusions were formed during explosive eruptions on the Moon approximately 3.7 billion years ago.
