Between April 20 and 25, 2015, the Director of the Hydrographic and Oceanographic Service of the Navy (SHOA), Rear-admiral Patricio Carrasco, joined by the Head of the National Tsunami Warning System Division (SNAM), Lieutenant Mr. Nicolas Guzman, participated in a Symposium commemorating the 50th anniversary of the PTWS held in Hawaii, United States, and later in the 26th Session of the International Coordination Group for the Pacific Tsunami Warning System (ICG/PTWS).

During the symposium, entitled "50 years of PTWS: Preparing the Pacific Ocean for the threat of tsunamis", technical and emergency issues were presented and discussed; the evolution of Warning Systems, Threat and Risk; preparing communities; Numerical Modeling, along with detection and dissemination of alarms.

The Director of SHOA was asked to present the experience of Chile in the Warning and Mitigation of Tsunamis, during which he said that "we must be prepared because we do not know when or where we will have to face the next event." He noted that "there is no system in the world able to predict earthquakes and tsunamis, so it is required to have everything operating in addition to redundant equipment."

Later, in the framework of the 26th Meeting of IGC/PTWS, Admiral Carrasco, in his capacity as Vice-President of the PTWS, outlined the main events that happened in Chile in 2014, and which generated Alarm States, Warning and Caution in the SNAM, as well as the contribution of Chile to the Pacific Tsunami Warning System.

Meanwhile, the Head of the SNAM Division presented the results of the Working Group of the Southeast Pacific, comprising Chile, Colombia, Ecuador and Peru, highlighting the main activities, among which is the implementation of a web platform to transmit seismic data and sea level, relevant to the decision-making; the exercises and tests of communications and training and/or exchange activities, noting that "all efforts to continue improving the Tsunami Warning Centers will be unsuccessful If there is no permanent training on the subject."

During the meeting, the report of results for the Tsunami Pacific Wave 2015 Drill was also addressed; the implementation of new products of the PTWC; the budget available for future activities and issues that are necessary to study during the intercessional period. Finally, the changes on the Board of PTWS took place, being elected President Ms. Filomena Nelson de Samoa; while as Vice-presidents Mr. Tomoaki Ozaki of Japan, Mr. Rick Baley from Australia and Ms.Tatiana Ivelskya from Russia were elected.

In this way the Director of SHOA presented the Vice-Presidency of the PTWS, having held the office for two periods of two years each (2011-2012 / 2013-2014); task during which the SHOA made great contributions to the system, which was recognized and appreciated by the participants.
