The eruption did not come as a shock to scientists because they were able to predict that it would happen at the end of the 20th century.
<h3>How did scientists predict this?</h3>
They analyzed the dates when the volcano erupted in the past.
They calculated the interval between each eruption.
They observed a pattern in the time between eruptions.
They realized that the eruptions happened every 150 years.
Based on this data, the scientists calculated how much time had passed since the last eruption and realized that this time would reach 150 years at the end of the 20th century, so they weren't surprised when the eruption happened.
