Advanced technology for tsunami detection and warning to work in Cuba

HAVANA, June 2nd Innovative technology is being developed in the eastern province of Santiago de Cuba for its inclusion in the island’s Tsunami Warning System, in charge of the National Center for Seismological Research (CENAIS), the Cuban media reported.

Dr. Enrique Arango, technical deputy director of the National Center for Seismological Research, explained that this equipment, of the technology known as GNSS-R, was donated by the French University of Toulouse, with whose experts Cuban seismologists maintain close collaboration links, according to a Prensa Latina (PL) news agency report.

The specialist indicated that these relations also include the Paris Institute of Physics of the Globe and the Martinique Volcanological and Seismological Observatory, which favor the application of various advances in these fields of scientific research and application, the news agency specified.

GNSS-R takes advantage of satellite navigation signals reflected from water, ice, or land surfaces, and fundamental geophysical properties of the reflecting surfaces can be derived from these measurements, Arango said, quoted by the agency.

The expert gave as examples the altimetric heights, humidity, or roughness of the ground, which can be correlated with the speed and direction of the wind over the water in a wide spectrum of applications that include weather forecasting and climate research.

Arango added that with the support of the German-Indonesia Tsunami Early Warning System, these investigations were expanded with the first successful ground-based experiments and studies related to future satellite-based tsunami early warning systems.

According to PL, the specialist pointed out that the installation of this receiver will also contribute with its data to the studies of the dynamics of the crust that CENAIS has been carrying out for more than four years through temporary stations with GNSS equipment.

Such measurements are aimed at determining the tensions accumulated in the plate boundary zone that can trigger a strong earthquake and, with the contribution of the new equipment, values ​​of coastal dynamics and their close link with the rise in sea level can be obtained.

The technical deputy director of CENAIS also highlighted the positive impact of these inquiries in the fulfillment of the Tarea Vida, a state strategy in pursuit of confronting climate change in Cuba, the news release concluded.
