By Bobby Ranoco LEGAZPI CITY, Philippines -- Clouds of ash and smoke sent panic through villagers living around a rumbling volcano in the central Philippines on Thursday, but experts said the alert level remained moderate. Mount Mayon, the most active of 22 volcanoes in the Southeast Asian country, began spewing lava, ash and rocks the size of cars last week, prompting volcanologists to raise the alert level to 3 on a 1-5 scale. The government has told 4,000 people to evacuate a danger zone...

Racine joined a group of rangers, scientists and journalists in a five-hour ascent of...
