Lisbon Earthquake--250 Year Anniversary

[Celestial Mechanic]

On 1755 November 1 probably the most destructive earthquake in European history struck Lisboa (Lisbon), Portugal. This earthquake was felt throughout Europe and some modern estimates suggest that it may have been a Richter 10 in strength. Tsunamis were stirred up in the Atlantic (yes, it can happen there too!)

Compounding the tragedy was the fact that it struck on All Saints' Day, a day of holy obligation, when most residents were at mass. At least 60,000 were killed in collapsed churches that morning.

If you can read portuguese or have enough interest to have it translated, here is site with some interesting information:

Not very deep on the scientific but with, as I said, interesting information and animations.
