Peru’s El Misti volcano shaken by swarm of 224 quakes: last major eruption occurred 540 years ago

August 28, 2012PERU Peruvian geologists have revealed that recent activity at El Misti signal that the volcano is active. Last Thursday researchers at the Geophysical Institute of Peru (IGP) found that El Misti – located 17 km outside the city of Arequipa – had recently recorded the highest amount of seismic activity than in the past five years. Engineer Orlando Macedo told El Comercio that 224 earthquakes were registered at El Misti – an event known as an earthquake swarm – and which signaled that the volcano was no longer dormant. El Misti, he said, experienced 143 volcano tectonic earthquakes, which were caused by the fracture of rock inside the volcano, due to sudden changes in pressure and temperature. Despite the recent increase in activity, the IGP said there were still no conditions for an eruption to occur at El Misti, which last erupted sometime between 1450 and 1470. For an eruption to happen, Macedo said, El Misti would have to experience continued earthquakes, which “would have to occur after long-term movements of magma, and causing these earthquakes known as tremors, with lava.” –Peru this week
US records show activity at the volcano in 1985 but Peruvian authorities said the volcano has been relatively dormant for nearly five centuries.

    Case in point.


  2. Alvin,

    Visiting your site daily for so long now. Continually trying to give you more dedicated viewers- and have been successful. It’s a good place to be reminded of the times since this world can easily distract us from staying conscious of what really matters.

    Thank you for all the work you’ve done in perusing (and posting) truth.

    Much love in Christ,

    So majestic yet so deadly. Beautiful picture would of never known it was a volcano.

    I am an 8th grader and we are doing a volcano/earthquake project, I’m doing mine on el misti. A lot of websites don’t give a whole lot of information, but this helped a bit. 🙂 Thank you.
