We studied the tsunami generated by the 1 April 2014 M _w 8.2 Iquique (Chile) earthquake using 20 Deep-ocean Assessment and Reporting of Tsunamis (DART) records and applying Fourier and wavelet analyses as well as performing numerical simulations. Deep-water tsunami wave heights were in the range of 0.8–35.0 cm. For the stations located more than 2,200 km from the source, the average wave height was 1.7 ± 1.1 cm. The observed tsunami arrivals were delayed by 1–17 min relative to the simulated ones based on the linear long wave equations, and the delays were proportional to the tsunami travel distances. A small initial depression was observed at DART stations located at distances >10,000 km from the source whereas, traditionally, an initial elevation is expected at stations located seaward of subduction zones. Fourier analyses showed tsunami governing periods of 21.1 ± 1.7 and 14.7 ± 0.7 min, corresponding to a fault length of 60–70 km and a fault width of 40–45 km. While the two 21-min and 15-min signals appeared in most DART stations during ~0.5 h following the conventional arrival times, the 15-min signal was delayed at some far-field stations. Distribution of maximum DART wave heights across the Pacific Ocean did not show a meaningful relation between maximum DART wave heights and directivity or distance from the source.
