LAURA KNIGHT-JADCZYK AND JOE QUINN
Since the 9/11 attacks, no book has provided a satisfactory answer as to WHY the attacks occurred and who was ultimately responsible for carrying them out - until now.
The eruption has formed a small steam-and-ash plume near the flanks of Pico, a small cone inside the main caldera at Fogo. Earthquakes became noticeable to people living on the island starting Saturday night and by morning, an eruption had begun. According to volcanologists monitoring Fogo, the volcano had been showing signs of unrest "for awhile ... " Most of the activity at Fogo for the past 500 years has occurred within the main caldera of the volcano and the eruption in 1995 was centered on the flanks of Pico. The eruptions are dominantly lava flows, although unlike shield volcanoes like Kilauea, Fogo erupts both low-silica basanite (similar to basalt but higher in alkaline elements like sodium and potassium) and high-silica phonolite (similar to rhyolite but higher alkalines). That eruption in 1995 created a lava flow field that spread over 6 square kilometers of the caldera floor.
