We report here the recent sea swell activities in the Pacific Ocean during the months of April and May in 2015. The first event of this kind was generated during the fag end of april around 27th and it was reported from the region of Island of Pascua in Chile and it hit all along the coast of Pacific region. Likewise, the second and third event was recorded during 8th to 11th and 19th to 21st May and it was detected continuously all along the coastal regions of Pacific Ocean. The sea swell events generated has been detected in Peru (Callao), Chile (Island of Pascua) and in Mexico (Cities of Mazatlan, Acapulco, Huatulco, Puerto Chiapas). Tide gauge evidences clearly support that the event has hit the coastal cities and likewise, satellite images indicates that considerable level of sea water has inundated the coastal cities. These sea swells generated during these events has generated huge waves and has travelled for long distances and it has caused considerable damage to the coastal cities in the Pacific coast. Identifying these types of strong sea swell events will help identify the low lying coastal cities and the limit of inundation in many places in also dependent on the coastal topography and depth in the region. During these different sea swell events reports of erosion and deposition has been reported from various places indicating that these type of events also have strong effects like a major hurricane or tsunamis which hit the coastal regions.
