1918 Puerto Rico tsunami run-up was 6 meters

1922 deaths are confirmed as being specifically related to tsunamis during the last 150 years. A 1918 M 7.5 earthquake resulted in a tsunami that killed at least 116 people in northwestern Puerto Rico. A runup of about 6 m has been documented by mapping, and sedimentary evidence for at least ...

The landslide's headscarp is at a water depth of 1200 m, with the debris flow extending to a water depth of 4200 m. Submarine telegraph cables were reported cut by a landslide in this area following the earthquake, further suggesting that the landslide was the result of the October 11, 1918 earthquake. On the other hand, the location of the previously suggested source of the 1918 tsunami, a normal fault along the east wall of Mona Rift, does not show recent seafloor rupture.

A magnitude 7.3 Mw earthquake on October 11, 1918, in the Mona Passage, west of Puerto Rico, was caused by displacement along four segments of a normal fault, oriented N-S in the Mona Canyon. The earthquake generated a tsunami with runup heights reaching 6 meters, causing extensive damage along ...

The shock was immediately followed by a tsunami with runup heights reaching 6 meters. Both the earthquake and tsunami caused widespread property damage with estimates beginning at $4 million in damage and more than 100 casualties.

The deepest point in the Atlantic, the trench marks the location where the North American plate is being subducted beneath the Caribbean Plate. It produced waves and runup on the order of 4-6 m that killed 40 people on the island (Mercado and McCann, 1998). The effects of the tsunami were recorded ...

The 11 October 1918 devastating tsunami in northwest Puerto Rico had been used as an example for earthquake‐induced landslide tsunami hazard. Three pieces of evidence pointed to a landslide as the origin of the tsunami: the discovery of a large submarine landslide scar from bathymetry data collected by shipboard high‐resolution multibeam sonar, reported breaks of submarine cable within the scar

The source of the devastating 1918 western Puerto Rico tsunami had previously been ascribed to · both an earthquake fault rupture (Mercado and McCann, 1998) and an earthquake-triggered · landslide (López-Venegas et al., 2008; 2015; Hornbach et al., 2008). Documented landslide ·
