Tsunami Map, Puerto Rico Earthquake, 1918

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 western and northern coasts of Puerto Rico. The earthquake and tsunami caused $29 million damage, 116 people were killed and 100 were reported missing. Map generated using Tsunami Travel Time (TTT) software: calculates first-arrival travel times on a grid for a tsunami generated at an earthquake epicenter. Map contours: 1 hour intervals: red 1-4 hour arrival times, yellow: 5-6 hour arrival times, green: 7-14 hour arrival times, blue: 15-21 hour arrival times. Maps were generated from earthquake epicenters in the NGDC Global Historical Tsunami Database using NGDC 2 Minute Gridded Global Relief Data bathymetry. Maps do not provide the height or the strength of the wave, only the arrival times.
