Volcanologist Bill Rose (right) and colleagues interview Don Patricio Parouche (center), an eyewitness of the catastrophic 1929 Santiaguito eruption. This eruption was the largest during the more than 75 years of lava dome growth, and produced pyroclastic flows that extended 10 km, nearly to the location of the village of El Palmar. At least 5,000 people were killed during this eruption.
