I noticed that DART almost always gives false tsunami alerts to the public. I analyzed the tsunami alerts in 2012. There were five tsunami alerts. All of them were false. According to the methodology used, a tsunami alert is received on the basis of the first burst of bottom pressure (red burst). Chart 1 attached. We checked the correctness of the methodology (attached graph 2). We studied the results of registration of changes in bottom pressure after the earthquake in Japan М=9.2. at the "close" - green line and "remote" red line buoy stations. It can be seen that the first wave from an earthquake arrives at a remote station (red line) and only then at a nearby station (green line). We calculated with what speed the first wave arrives at different DART buoy stations. The map is shown in (#2). The arrival speed of the first wave is 1.1-3.9 km/s. Now the main thing. The maximum speed of a tsunami is 0.25 km/s. The first wave that hits the DART station is not a tsunami.
Short theses on the physics of the tsunami generation process. Wrong hypothesis. Water doesn't compress. With a sharp rise in the bottom, the level of the ocean also rises and a wave forms around the epicenter as if from a stone thrown into the water. Signs of a false hypothesis:
With earthquakes of the same strength, the height of the tsunami wave is proportional to the thickness of the water layer above the epicenter. Earthquakes in oceanic trenches with depths greater than 7 km generate tsunamis of maximum height.
Our theory of tsunami generation:
Water is compressed by 1%. In the ocean at a depth of 7 km, it is compressed by 70 meters. At a depth of 1 km, water is compressed by 10 meters. This is a rough estimate. During a water hammer during an earthquake, the pressure of the water column decreases and the water expands by 1%. The ocean level above the epicenter of the earthquake rises and this is a tsunami. This happens several times. The number of tsunami waves is greater than one.
Мы знаем, что при землетрясении, как в кимберлитовых трубках (или верней, кимберлитовые трубки - копия происходящего в гипоцентре при схождении волны к месту эпицентра и под углом снизу - вверх из-за формы Земли) идет взрывное сжатие и.... снизу - вверх. Гравитационные воздействия действуют на всю воду и при этом работает вся масса.
