It’s summer and you have been planning to take a vacation in Naga City in Bicol where your parents live so you bought a bus ticket early. While you were still in

Manila a few days before your scheduled trip, you saw the news on TV that Mt. Mayon in Albay has erupted and thousands of people were evacuated. Is it safe for you to still go on vacation in Naga?

• Yes, because Mayon is a 2-3 hour drive from Naga. The lava can’t go that far and based on its past eruptions the people in Albay are the ones mainly affected but be prepared to encounter some traces of ash.

• Yes, because Mayon is too far for the pyroclastic flow to reach Naga and the bus will never pass through Albay anyway so it’s safe to take the trip.

• No, because the ashes will surely be flown by the wind and will eventually reach Naga, thus, ruining your vacation.

• No, because the eruption can continue for weeks
