Pompeii

Scientists have uncovered a geological explanation for why some volcanic eruptions are more explosive than others.

Professor says expanded excavations at Pompeii come at the expense of vital information about one of the world's most dangerous volcanoes.

The city, preserved in time after the eruption of Vesuvius in AD 79, receives over 2.5 million tourists a year.

"When a volcano is silent for a long time, its first explosion can be catastrophic," researcher Ivan Kulakov said.

To advertise its services, the business used colorful frescoes—which have survived nearly 2,000 years under volcanic ash and pumice.

Forensic analysis of skeletons found in ash deposit reveal what happened to people in path of volcano.

He survived the first showers of ash and rock, but was toppled as he tried to flee the city.

In a race against tunneling looters, archaeologists stumbled on an "extraordinary" discovery just outside where the lost city walls once stood.

In 79 AD, this seven or eight year old child fled to the city's Central Baths for shelter.

There may have been antimony lurking in the Roman town's water.

Archaeologists are excavating dwellings so well-preserved they include footprints and dishes with remnants of meals still inside.
