The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Sierra la Primavera volcano is a volcanic complex immediately west of Mexico's second-largest city Guadalajara. It contains a large caldera that formed about 95,000 years ago and produced major pumice flows forming ignimbrite layers.
The volcano could still be active, although the last activity probably dates back more about 30,000 years ago, when it formed a lava dome. Today, there are steam vents and hot springs at many locations of the complex.
Kelut volcano's lava dome in 2007: One of the most impressive lava dome eruptions in recent years. A new dome formed in the crater lake of Kelut volcano (East Java) in late 2007. Enjoy some unique pictures.
Latest quakes in Greece: Greece has a lot of earthquake activity, but most of them occur around the margin of the Aegean microplate. The Cycladic islands are located in its center and therefore seismically comparably quiet.
