Imagine waking up to the news that the ground beneath your favorite holiday destination is rumbling—and not in a good way. That’s exactly what happened in Tenerife recently, sending shockwaves through residents and tourists alike. But here’s where it gets controversial: while officials are urging everyone to stay calm, the island’s massive volcano has been acting unusually, sparking fears of a potential eruption. So, what’s really going on?
After an unprecedented hour-long rumbling was detected beneath Mount Teide on Tuesday, the Civil Protection Plan for Volcanic Risk in the Canary Islands (Pevolca) held an emergency meeting. Scientists quickly reassured the public that there’s no immediate danger, but they’re staying ‘vigilant’ after several intense seismic episodes. A shorter tremor was also recorded on Wednesday, adding to the unease. Itahiza Domínguez, director of the National Geographic Institute in the Canary Islands, explained that while these low-frequency signals are common, Tuesday’s event was the longest ever recorded in the past decade.
And this is the part most people miss: these signals are caused by vibrating fluids like magma, deep underground—typically 10 to 12 kilometers below the surface. They’re undetectable without specialized equipment, but their prolonged nature has raised eyebrows. Domínguez clarified that while Tenerife is volcanically active, predicting an eruption is impossible. It could happen in a year or 50—or not at all. For now, he assured, ‘There is tranquility.’
Rosa Dávila, president of Tenerife’s governing body, echoed this sentiment, stressing there’s no evidence of an imminent eruption. She highlighted that Mount Teide is one of the most monitored volcanic systems globally, with no changes in gas emissions or ground deformation. ‘We’re not seeing what we saw in La Palma before its 2021 eruption,’ Domínguez added. But here’s the kicker: while this activity is new for Tenerife, it’s common in other volcanoes worldwide. Does that make it less concerning, or more?
To prepare for the worst, the local government is staging emergency drills in Guía de Isora and Santiago del Teide, teaching residents to use emergency equipment. Town mayors have also been instructed to update their emergency plans. These preparations follow a massive drill in September, where residents received phone alerts and some even evacuated—the largest such exercise the island has ever seen. Similar drills are rare, only conducted in places like Hawaii, Stromboli, and Sicily.
The last eruption in Tenerife was over a century ago, but the recent activity has reignited debates about volcanic risk. Is the island truly prepared, or are we underestimating the threat? Let us know your thoughts in the comments—do you think Tenerife’s officials are doing enough, or is there more to be done? The ground may be rumbling, but the conversation is just heating up.
