What the record says

NCEI’s account, from the sources it cites.

382 A.D. 36 N, 10 deg 50 min W, SW Cabo San Vicente, Portugal. (reference #1193)

Moreira de Mendonca (1758) lists an earthquake followed by a tsunami at Saint Vincent Cape in the year 382 A.D., based on the Portuguese historian Brito (1597). Brito bases the occurrence of this earthquake on the testimony of Laymundo, a presumed chaplain of the Spanish Visigoth King Don Rodrigo. But there is no historical evidence of the existence of Laymundo, who is, then, a creation of Brito, therefore the historical base for the earthquake is not valid (Udias 2015). Brito could have had other sources, but they are not given. (reference #12772)

382 A.D.; Magnitude 7.5; 36N 9.5W (reference #11164)

This earthquake is first listed by Moreira de Mendoza (1758) "This year there was an earthquake in the whole world. The sea shores of Portugal suffered a great deal. Some islands were submerged of which there is still some rests in front of Cape St. Vincent" [...] Moreira de Mendoza (1758), the first to list this earthquake, cites Laymundo according to Brito. Bernardo de Brito (1569-1617) is the author of the history Monarquia Lusitana. The fictional Laymundo (a character made up by Brito) is supposed to have been the chaplain of the last Visigoth King Don Rodrigo. His attributed account is a well-known fable invented by Brito, so it does not have any historical value. There is, then, no serious basis for this earthquake.[...] Galbis Rodriguez (1932, 1934) lists an earthquake in 536 saying: "Spain was afflicted by several sicknesses, plague, earthquakes and storms" (Afligieron a España varias enfermedades, pestes, temblores y tormentas) and cites Mariana, vol. 1, book 2, chap. 10, but there Mariana is talking about the earthquake of 217 B.C. This is a mistake. (reference #12774)

382 A.D. 36 deg N, 10 deg 50 min W, Portugal. (reference #2764)

The 382 earthquake was felt around the Mediterranean (e.g. Sicily, Greece, and Palestine) and in Iberia. (reference #8635)

Many subsequent authors have believed that 382 AD is the year to which Brito dates the earthquake (Moreira de Mendonça 1758, p. 26; Galbis 1932, p. 7; Oliveira 1986, p. 133; Baptista and Miranda 2009, p. 26), when in fact he does not mention any specific date for this event. (reference #13258)
