Answer:
Earthquakes, gas emissions, ash/steam venting, lava buildup, dome collapse, explosion, eruption.
Explanation:
1 Earthquakes - swarms of earthquakes happen first.
2 Gas Emissions - gas begins to emit from the volcano.
3 Ash/steam venting - ash and steam begin to fill the air.
4 Lava Dome Buildup - lava builds up, getting closer to the dome of the volcano.
5 Dome Collapse - the dome collapses, leaving the lava free to burst out.
6 Magmatic Explosion - magma begins to escape from the volcano.
7 Pyroclastic Eruption - finally, the volcano erupts.
