Imagine a volcano waking up from a 12,000-year-long deep sleep—that’s exactly what happened in Ethiopia! The Hayli Gubbi volcano, sitting quietly near the Eritrean border in the Afar region, suddenly erupted with a thunderous blast on Sunday. Ash bellowed skyward, soaring a staggering 14 kilometers high and painting the sky with thick clouds. This sleepy giant’s awakening caused shockwaves not just in Ethiopia but across the world. The ash drifted far and wide—touching Yemen, Oman, India, and even northern Pakistan. Air quality took a hit, prompting sharp safety warnings from India’s DGCA about flight disruptions. The eruption lasted several hours in the heart of the East African Rift Valley, a zone famous for dancing tectonic plates and rumbling underground activity. Why is this eruption such big news? Because Hayli Gubbi hadn’t shown any flames or smoke in over 12,000 years! The Smithsonian Institution’s Global Volcanism Program confirms that this volcano was snoozing throughout the entire Holocene epoch, making this sudden burst truly rare and exciting for scientists. So, what brings a volcano like this back to life? Experts explain that “dormant” means the volcano sleeps but hasn’t died. Underneath, molten rock or magma waits silently, and when the Earth’s tectonic plates slowly wiggle and pressure builds inside, the volcano can suddenly explode back into action. To break it down: dormant volcanoes can nap for thousands of years, but the fire inside still burns deep underground. Hayli Gubbi just showed us this is no fairy tale but real earth drama! Scientists warn this area is still a mystery. Arianna Soldati, a volcanologist from North Carolina State University, told Scientific American, “So long as there are still the conditions for magma to form, a volcano can still have an eruption even if it hasn't had one in 1,000 years or 10,000 years.” The Afar region, part of the East African Rift Zone, is a hotspot where the African and Arabian plates slowly pull apart 0.4 to 0.6 inches every year, stirring underground cauldrons. Juliet Biggs, an earth scientist from the University of Bristol, said, “I would be really surprised if [more than 12,000 years ago] really is the last eruption date.” She pointed out that satellite images show signs the volcano might have spat lava more recently than we thought. “To see a big eruption column, like a big umbrella cloud, is really rare in this area,” she added. Thankfully, so far no one has been hurt. But local people, mostly pastoral communities who live close by, might face serious troubles due to the ash and debris drifting down. This epic awakening of the Hayli Gubbi volcano reminds us that nature’s slumbering giants can roar anytime, and there is still so much to learn about the fiery forces shaping our planet!
