Zhang Peng said that in the five years he was here, the volcano would throw a tantrum occasionally, but it had never erupted before. Therefore, it should not be an active volcano, but instead could be considered as dormant. As for when the volcano would erupt, Zhang Peng could not give an answer to the question. Nobody could possibly answer that question as they were just ordinary people, they were not seismologists.
Perhaps the volcano would only erupt after they died, and it had nothing to do with them at this point of time.
