The annual summit of the Caribbean Community, Caricom, will take place between July 28 and 30, in Grenada, to analyze the issue of the climate crisis and its effects on the environment.

The event was initially scheduled for the 3rd to the 5th of the current month, but had to be rescheduled due to the passage of Hurricane Beryl, which caused disasters as it passed through the region.

Grenada Prime Minister Dickson Mitchell said: “We postponed the meeting, but we intend to hold it because we believe it is an opportunity for all of us in Caricom to come together and show solidarity and support for Grenada, Saint Vincent and the Grenadines, Jamaica, Cayman Islands, Barbados and Saint Lucia that have suffered the impact of this terrible hurricane.”

The 47th edition of the summit will allow Caribbean leaders to meet in the Granada district of Saint George, with the purpose of discussing topics such as “environmental catastrophes, the climate crisis and crime that affect the Caribbean.”

It is important to remember that the Caribbean Summit is made up of Antigua and Barbuda, Barbados, Bahamas, Belize, Dominica, Grenada, Guyana, Haiti, Jamaica, Montserrat, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Suriname and Trinidad and Tobago.

According to new research published in Geophysical Research Letters, many river valley floods are monitored by river gauges, which can roughly track the water level of a flood. However, meters can be in short supply, infrequently updated, and at risk of being swept away in a flood. Seismic stations are installed at a safe distance from streams and detect not only ground shaking due to earthquakes, but also vibrations from explosions, landslides, storms and floods.

Previous research on seismic flood monitoring has been limited to detecting a flood and indirectly tracking its evolution, particularly for glacial floods.

The new study goes a step further, using seismic signals to estimate flood velocity, water level and debris, Michael Dietze, lead author of the study and a scientist at the University of Göttingen, said in a statement. “This study paves the way for real-time flood anatomy, with values ​​that can be used” to provide real-time hazard updates, Dietze said.

Researchers have pieced together the fatal spread of a disastrous 2021 flood in Germany, which killed nearly 200 people. The team used an existing seismic seismometer station near the flood path as a flood detection and monitoring tool. These seismic data were the only systematic source of quantitative information on how the flood evolved because three existing water level stations along the main river were destroyed prematurely.

Flood Sensor

The team found that the seismometer illustrated the flood path for an hour as floodwaters passed through the steep and winding Ahr Valley, south of Cologne. By combining mathematical models, the researchers were able to estimate how fast the flood moved, extract information about water level rise, and estimate the amount of debris, such as gravel, cars, and oil tanks, that was being swept away by the flood.

Measuring the “seismic footprint” of a flood (its magnitude, speed and trajectory) in real time could be used for protection against future floods, providing the information needed to optimize flood behavior models for warning and rescue initiatives.

Dietze and his colleagues are currently working on a plan to identify more areas at risk of flooding and equip them with pairs of inexpensive “watchtower” seismometers. Using two or more seismic sensors, rather than a single sensor as in the study, would provide scientists with more robust information, Dietze said. Installing such “watchtowers” would cost a fraction of a percent of the damage caused by future flooding, according to the researchers.
