With the installation of the new Buoy DART 4G 220 kilometers NW of Valparaiso, Chile now counts with 5 instruments for early tsunami detection.

A year after  the installation of two prototypes of the Buoy DART 4G System  in the coast of Mejillones and Constitución, on December 5, at the Hydrographic and Oceanographic Service of the Navy (SHOA), its director Rear-admiral Patricio Carrasco, along with the Deputy Director of the National Office for Emergencies of the Ministry of Interior and Public Safety(ONEMI) Mr. Victor Orellana; the Director of the Centro de Investigacion para a Gestion de Desastres Naturales (CIGIDEN) Mr. Rodrigo Cienfuegos; and the Director of the National Seismic Centre (CSN) Dr. Sergio Barrientos, announced the installation of a cutting-edge buoy 220 kilometers NW of Valparaiso.

According to the naval authority, the anchoring of this buoy covers a current breach between the Buoy Dart II, located in Caldera and DART 4G, in Constitución, allowing more coverage along the country and increasing the capacity to detect tsunamis at a closer distance to the trench where earthquakes that lead to tsunamis originate. “With the installation of this new buoy through the Scientific Ship AGS Cabo de Hornos we will be able to better predict, and will be more covered in an area where there is no other buoy”, said admiral Carrasco.

The deputy Director of the ONEMI, Victor Orellana, emphasized the labor of the scientific and technical organisms whose contribution of capacities is strengthening a Monitoring and Early Warnings System when facing a tsunami threat. An example of this is the joint work with ONEMI, CSN, SHOA and academic institutions.

Rodrigo Cienfuegos, from CIGIDEN, expressed that this organism has worked very closely with national institutions in charge of Risk Management. The “SIPAT System” was a job developed jointly with the Universidad Federico Santa Maria and CIGIDEN, and today we are happy to be participating and keep on supporting the work of SHOA. This new buoy and network will, undoubtedly, allow us to obtain more information to analyze the consequences of tsunamis and make progress in reducing their impacts”.

Finally, Dr. Barrientos acknowledged the permanent need to learn about these events and mentioned the support that the installation of this new buoy will add to that, since through it, it will be possible to obtain more precedents regarding the behavior of the tsunamis. He also mentioned that the installation of this 5th buoy in the central-north area is based on the need that this zone had not been covered by these instruments, and it’s where you would expect more seismic activity. “It is very likely for earthquakes to happen in those places where none have generated in the last 10 to 100 years”.
