Volcanic Activity In Columbia

In the southwestern part of Columbia lies a stratovolcano by the name of Galeras. This volcano is over a million years old. With frequent movements by the Nazca, North Andres and South American plates,Galeras continues to erupt and pose a serious threat towards the city of Pasto. Keep in mind that there is a population of over three thousand people living in this city. Regarding its eruptions, it has been erupting since 2008, but the hasn't been an eruption that posed a extreme threat towards the city. Nevertheless, city generals are ready for when the big eruption will arrive. Looking at its past eruption history, at times it has erupted with a lack of seismic activity. In 1993, a group of volcanologist and visitors toured the active volcano of Pasto.Soon enough without a warning, there was eruption that killed nine people and also injured six people.

Interesting fact from Geology.com. Seismic activity at Galeras has displayed characteristic signals known as "tornillos". "Tornillo" is Spanish for 'screw', and these seismic signals are so named because their shape on a seismograph resembles a screw with a wide head and tapered tail. At Galeras, these signals are generally regarded as short-term precursors to explosive eruptions. 
 Isnt this Ironic or what!!!!

Over the years,studies shown that the volcano has been active for the past 4,500 years....I know what you're thinking..That's amazing..

A couple weeks there was an article from the webpage,"Wired" stating that there has been a discovery of a new volcano found in central Columbia. Few scientist say that this volcano isn't something you could find in your textbooks. Nevertheless it has revealed what they call a pyroclastic ring that forms a crater. The scientist also found some deposit of pumice near the crater. But as of now, the potential volcano is temporarily know as a hot spring.But there is alot of wonder whether there is magma forming beneath the surface. Personally, I'm looking to see to what happens in the few months with volcano.  
You see that crater is forming! Remember that over time volcanoes like Galeras can eventually grow into something humongous.
