Hi,
As my information Tortola is a mountainous island 13.5 miles (19 km) long and 3 miles (5 km) wide, with an area of 21.5 square miles (55.7 square km). Formed by volcanic activity, its highest peak is Mount Sage at 1750 feet (530 m). Tortola lies near an earthquake fault, and minor earthquakes are common. So On Tortola the first rays light up the green slopes that fall from Mount Sage to secluded palm-fringed beaches far below. The first ferry of the day is going out as the first sail boat appears on the horizon. The shops are laying out their West Indian wares: spices, jams, rums, soaps, and hand-crafted jewelery.
