Magnitude 7.2 earthquake hits Peru amid worrying seismic sequence

Peru's 7.2 quake doesn't come alone: what's behind the seismic sequence

The magnitude 7.2 earthquake that shook Peru is not an isolated event. In just a few months, the ground had already trembled hard in Venezuela and Colombia, and now it's Peru's turn. The timing raises an uncomfortable question: is this a normal streak, or is something changing underground?

A catalogue of quakes and volcanoes that invites speculation

Those who trinc seismic activity point out that the phenomenon goes beyond South America. In recent weeks there have been earthquakes in Granada and on the Mid-Atlantic Ridge, the latter measuring 7; Mount Etna and Stromboli have been spewing lava again; and there are seismic swarms between Tenerife and Gran Canaria and in the Tyrrhenian Sea. The list is long and, taken as a whole, it unsettles even the least apocalyptic among us.

Some frame it within "end times" prophecies, while others recall the cover of The Economist that placed Spain in September as the epicentre of something. There is no way to verify that, but the conversation is already underway.

What the seismographs say versus the prophetic noise

Geology has a boring answer: the Earth shakes all the time, everywhere; the human brain tends to see patterns where there is only statistical chance. But the accumulation of events along the Pacific Ring of Fire and the Alpine arc deserves attention. What you cannot do is predict anything concrete from a magazine cover.

Whether September surprises or not, the lesson is the same

With the data available, no one can say where the next big quake will strike. Seismographs don't work with magazine covers or prophecies, but with historical records. Whether the current sequence is a warning or just a fluctuation, the coming months will tell. The answer, as almost always, lies underground.
