The Soufrière Hills Volcano is not a specific age, but rather a volcanic complex that has been active for millions of years.

Here's a breakdown:

* Formation: The volcanic complex itself formed around 1.8 million years ago.

* Recent Activity: The current active dome, which is the part that's been causing the recent eruptions, is only about 1,000 years old.

* Last Major Eruption: The most recent major eruption started in 1995 and continues to this day, though the intensity has varied significantly.

So, while the volcano itself is millions of years old, the specific area causing the current eruptions is much younger.
