Call Off the Crazy: Quake Prediction Falsely Attributed to Decades-Dead Quack Was Wrong

By Patrick Morgan | May 12, 2011 11:37 am

It’s said that all roads lead to Rome, but on May 11, the opposite was true as thousands of Romans fled the Eternal City for fear of a massive earthquake. The mass exodus was spurred by  internet rumors that said an Italian pseudoscientist predicted a devastating quake on this date over thirty years ago. It goes without saying, but here’s why you probably shouldn’t trust the seismic predictions of someone who thought earthquakes were caused by planetary alignments:

Meet Raffaele Bendandi, a “scientist” who believed that aligned planets could change Earth’s gravitational force and trigger earthquakes. He’s thought to have correctly predicted a 1915 earthquake in Avezzano, Italy, but he didn’t become famous until he “correctly” predicted a January 4, 1923 earthquake in Le Marche. (He was actually two days off.) It was close enough for Benito Mussolini, though, who later granted Bendandi a knighthood.

While Bendandi might’ve gotten lucky a couple of times, it’s well established that planetary alignments don’t cause earthquakes. “The force from aligned planets is irrelevant compared to the tectonic forces of the Earth’s plates whose movements create real earthquakes,” seismologist Lucia Margheriti told CNN. “None of the big earthquakes of the last century happened with particular planets’ alignment.”

Plus, earthquakes are just too unruly to predict 30 years in advance, and (correct) predictions that pinpoint days are impossible even with our latest technology. “To predict an earthquake, you need a precursory signal of some kind, and we’ve yet to find anything reliable,” USGS geophysicist Tom Parsons told LiveScience. “A lot of things have been tried in terms of looking for electrical signals or gas release, and paying attention to animal behavior, but none of these have turned out to be reliable.”

Granted, Italy as a whole is one of the most seismically active countries in Europe: The African tectonic plate is ramming into the Eurasian plate, which has formed the Alps, and Italy has major faults running north-south down its spine, the Apennine mountains. Even by midday on May 11, the country had experienced more than 22 small earthquakes. Rome is an entirely different story because it doesn’t lie near a major fault line. “You feel earthquakes in Rome sometimes, but they happen elsewhere,” Parsons told Live Science. “So in terms of predicting a massive earthquake there, it’s already a kind of unlikely place.”

Topping everything off, it isn’t even clear Bendandi’s prediction is anything more than an internet rumor. “I can state with absolute certainty that in Raffaele Bendandi’s papers, there is no prediction of an earthquake in Rome on 11 May 2011,” says Paola Lagorio, the president of the Osservatorio Geoficico Comunale of Faenza, a foundation that honors Benandi. “The date is not there [in the papers], nor is the place.”

Despite the many holes in this earthquake prediction, many Italians are taking it seriously. It’s reported that day-off requests made by public employees are 18% higher on this day than on the same day a year ago. In addition, “in some areas of the city, nearly 50% of the shops [were] closed. On doors are quick handwritten notes: ‘Closed for inventory.'” And now that May 11 has come and gone without a rumble, don’t think Romans are in the clear: Bendandi also predicted two more catastrophic quakes for May 2012, the very same year the world will not end.

    wkwkwkwkwk,…too many fault predictions! are they playing Angel?

  • Mike

    Well, well, well, looks like Bendandi might have been wrong on the exact place, but he nailed the day didn’t he? Skeptical now?

  • LOL


    Here are some earthquake stats.

    As you can see there are on average 50 earthquakes each day. So if I predict there will be an earthquake somewhere in North America tomorrow and I am right, surely in light of your viewpoint this proves my ability to predict the future.

    Since this seems an adequate amount of evidence for you to believe in psychic abilities , I just have one (likely very profitable) question for you.
    Are you willing to send me $10000 for lottery number prediction skills?
    I’m sure eventually i’ll pick a few good numbers…given enough time.

    Irrational now?

    There was a large earthquake in Spain this same day. Not too far off the mark.

    Well…lets see, Bendandi was close this time in that there was a notable earthquake on that day because it affected a population center. Why did he think Rome was the target?? If you look at his hit vs. miss rate…would you really prescribe a theory when all the other planetary alignments coincided with few if any notable earthquakes. The magnitude of the Spain earthquake was not in itself very strong compared with all earthquakes that happen on any given day…look up the stats in LOL’s link. You’ll see that on average there are over 1300 magnitude 5.1 – 5.9 quakes per year. Given that this averages to over 3 Magnitude 5 quakes per day, if a quake of that magnitude didn’t occur on a given day…then it would seem strange.

    In other words, if the planetary alignment should have produced a larger earthquake than average for any given day, then we can consider this myth busted.
