The researchers explained that recent volcanic eruptions in St. Vincent and Iceland have not resulted in death
It is known that on land increased seismicthe activity releases small amounts of radon, a naturally occurring radioactive gas, into the soil a few days before an earthquake. Therefore, detecting a burst of radioactivity on the seabed can help predict underwater earthquakes. However, as in many other areas of ocean science, we have little knowledge of what happens to the radioactivity on the seabed, and to detect a spike in radioactivity, we need to have raw data.
Due to plate movement, the Pacific Ocean floor is now deep under China
Measuring anything on the seabed is very difficult.Scientists noted that electronics do not like water, and this is a difficult place where high pressure and other forces, like waves and currents, persist. Seismographs are less reliable underwater, where vibrations from sea waves and winds can drown out vibrations from incipient earthquakes.
This task will be solved by the drone RAMONES(RadioActivity Monitoring in Ocean EcoSystems). However, the radioactivity sensors are designed for relatively quiet operation on land, so the RAMONES team has to redesign them to work in the seabed. So scientists can find thin layers of cesium-137, which is released from the earth's crust during underwater drilling of oil wells.
“The situation at sea is not fully known, sincethere is a lot of legacy waste, but no monitoring has been carried out. ” The team hopes that their drones will be able to help coastal communities and environmental monitoring groups better monitor this situation, ”the scientists noted.
