Later the experts confirmed partial damage in the national and local TV towers. These fiery peaks have belched up molten rock, hot ash, and gas since Earth formed billions of years ago. Approximately 400,000 people live within the volcano's zone of influence. Facts About Galeras The active cone began growing 4,500 years ago, and its eruptive style has been characterized by relatively small Vulcanian explosions. A hydrothermal eruption occurred on 7th June 2002 at El Pinta Crater. Its earliest activity during the Holocene has been dated at 7050 BC 1000 years through radiocarbon dating. The eruption ejected lapilli, ash, and clay. Projectiles fell 3 km from the crater starting fires. They have gentle slopes which have been structured by the fluid basalt lavas. No injuries or damage were reported.[12]. This was the tenth such eruption of the volcano in the previous year, and the first of 2010.

The active cone of the volcano, which has grown in a large horseshoe-shaped caldera created by a large edifice collapse, has been erupting for the past 4,500 years, but the volcanic complex has been active for more than a million years. An eruption can be explosive, sending material high into the sky. The dominantly andesitic complex has been active for more than 1 million years, and two major caldera collapse eruptions took place during the late Pleistocene. An eruption occurred at Galeras volcano, Colombia on 20th November 2009, causing 1000 evacuations. Its summit rises 4,276 metres (14,029ft) above sea level.

Seismic B-types had been used successfully to predict eruptions on other volcanoes. These are the cinder cone volcano, the stratovolcano, and the shield volcano. Galeras erupted again on August 25, 2010, with an ash plume visible in the air. Subsequently, part of the caldera wall has collapsed, possibly due to instabilities caused by hydrothermal activity, and later eruptions have built up a smaller cone inside the now horseshoe-shaped caldera. Jessica earned her Bachelor of Science degree from the College of William and Mary, and worked for a year at the American Geological Institute in the Education/Outreach Program. The second was some time between 40,000 and 150,000 years ago, in a smaller but still sizable eruption of 2 cubic kilometres (0.48cumi) of material.
