Answer

Brief Explanations:

Primary succession occurs in an area with no pre - existing soil or organisms, like after a volcanic eruption when new rock is formed. Secondary succession occurs in an area that has had a previous community and soil, such as after a forest fire. Here, primary succession started with the volcanic eruption and new rock formation. Then, forest fires led to secondary succession events.

Answer:

Primary succession occurred, followed by several secondary successions.
