Where the waves reached
The source (white) and every runup with a place, colored by the water height recorded there. A ring is a runup NCEI marks doubtful.
- Under 1 m
- 1 to 3 m
- 3 to 10 m
- 10 to 30 m
- 30 m and more
- Height not recorded
Travel times
How long the first wave took to reach each part of the ocean, one line for each hour up to 24, estimated from the source and the depth of the sea.
The travel times are computed in your browser, which needs JavaScript.
- 1 to 4 hours
- 5 to 6 hours
- 7 to 14 hours
- 15 hours and more
Computed in your browser the way NOAA’s own travel time maps are: the wave travels at the square root of gravity times the depth, over NOAA’s ETOPO1 depths averaged to a 10 arc-minute grid. Checked against NOAA NCEI’s maps for 21 tsunamis over the first 24 hours, these lines fall within 10 minutes of NCEI’s at half the points compared and within 52 minutes at 9 in 10. They give when the first wave could arrive, not how high it is; bays, harbors and island chains finer than the grid can see it later. Not for use in a warning: see tsunami.gov.

Aiello (Calabro) - 408 houses houses destroyed with 655 people killed; Belsito destroyed, 116 killed; Grimaldi destroyed, 234 killed; Carpanzano razed to ground, 495 killed; Conflenti Superiore houses destroyed, 229 killed; Malito destroyed 173 killed; Motta Sta Lucia damaged, 532 killed; Nicastro all destroyed, 1,200 killed; Piane Crati razed, 102 killed; Sambiase destroyed, 216 killed; Scigliano Diano destroyed, 451 killed; Feroleto (della Chiesa) damaged, 126 killed. Focus of earthquake located near Nicastro. Earthquake was felt on Sicily (reference #2130).
1637, March 27, 15:05 UTC. Tyrrhenian Calabria, 39o02'N, 16o17'E, magnitude 7, intensity XI. Tsunami reliability 2, intensity 2. Strong shock located near Nicastro, Calabria, about 15 km far from Tyrrhenian coast. More than 10,000 victims, though the exact number is unknown. Severe damage in many localities: Cosenza, Nicastro, S.Eufemia, Girifalco, etc. Felt in a very large area, involving the whole Calabria. Kircher (r10) mentions an intense volcanic activity at the Etna and Stromboli volcanoes in the day immediately before the shock. Many coeval sources are available.
Scarce information on the tsunami.
At Pizzo Calabro the sea was reported to withdraw by about 2000 paces leaving the sea bottom dry and then to come back to its normal level just before the shock (Recupito, r11).

Every runup
Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
