A five-foot tsunami has hit tourist beaches in parts of Majorca and Menorca. A wave measuring almost five feet hit Ciutadella on the west coast of Menorca in the early hours of Monday morning. Nearby beaches were also flooded by the meteotsunami, called a rissaga in Catalan Spanish. These are large, tsunami-like waves are triggered by disturbances in air pressure caused by fast-moving weather events, like thunderstorms.
The freak weather phenomenon also affected holiday resorts in Majorca, with seawater flooding bars and terraces by the coast in Andratx and covering beachside roads.
Andrew Sibley, of the Met Office, said: ‘In certain conditions thunderstorms can trigger a phenomenon known as a meteotsunami, particularly in areas where the depth of the sea is sufficient to amplify wave height through resonance. The updrafts and downdrafts within a thunderstorm can create small and short-lived pressure changes, leading to initially small sea waves.
These waves can then be amplified dramatically by resonance between the speed of the thunderstorm system and the speed of the wave if they are in phase. The speed of the sea wave is related to the sea depth. Such waves can also be funneled by coastal bays, estuaries and inlets. Meteotsunamis have been observed globally, including around the coast of Britain, but some regions like the Mediterranean are more susceptible.‘
Boat owners in the resort on Majorca’s south west coast were filmed desperately trying to protect their boats, with the footage shared widely on social media. The strong current broke the ropes of a historic sailing boat used by the Majorca Island Council, which had to be rescued by sailors and brought back to port as it drifted out to sea.

There were no reports of any injuries and the meteotsunami occurred when the beaches were largely empty before holidaymakers started to arrive for their daily dose of sun.
Meteotsunamis, also known as meteorological tsunamis, are tsunami-like waves generated by rapid changes in barometric pressure. Scientists are only beginning to understand the meteorological phenomenon.
Meteotsunamis have been observed in a number of places around the world, including the Mediterranean and Adriatic Seas, Gulf of Mexico, and Atlantic Coast.
A meteotsunami that struck Nagasaki Bay, on the island of Kyūshū in March 1979 killed three people. Last summer, one of the towering waves was filming crashing into the Netherlands, catching beachgoers off guard.

Identifying a meteotsunami presents a unique set of challenges to scientists, since the characteristics of these waves are so similar to other meteorological phenomenon, including tsunamis.
Meteotsunamis can also easily be confused with a wind-driven storm surge or a seiche, which is a standing wave in an enclosed or partially enclosed body of water.
According to the United States National Oceanic and Atmospheric Administration (NOAA), these uncertainties make it difficult to predict a meteotsunami and warn the public of a potential event.
However, scientists are working to pinpoint the exact atmospheric conditions which are most likely to generate a meteotsunami in an effort to improve advance warnings.

Listen to the sounds of rockfalls at Kīlauea Volcano’s summit in this short video taken from the northeast rim of the caldera. At 2:42 p.m. HST on July 12, 2018, a collapse/explosion event at Kīlauea’s summit released energy equivalent to a magnitude-5.3 earthquake. Rockfalls that occurred in Halema‘uma‘u and along the steep summit caldera walls during the event can be heard in this video.

If you see Intellicast Radar around Brisbane Australia, you can find very interesting movement of UFOs. Right now, inside the city of Brisbane, the temperature 46 and 36 degree in the very close distance. 10 degree difference within 50km distance is very strange. 36 degree location is right on the Military Facility, Amberley Aerodrome = RAAF Base Amberley is a Royal Australian Air Force military airbase. The lowest average temp of Brisbane around this time of the year is 51.

Starting at 4:00 on this video, you can see many massive iron doors inside the abandoned Reptilian Secret Base. These kinds of massive iron doors are the signatures of their base. They feel safer with those massive door. In Japan, the Ministry of Defense building is connected to a huge Reptilian Secret Underground Base at B6 (6th floor of basement), Minister of Defense told to media. That became a small news. He said “There is a massive iron door on B6 of Ministry of Defense building. Believe or not, there are some creatures living there, and of course, they are NOT humans.”
