Protect your head and your back, too, because under such weight, obtaining oxygen will almost feel like a secondary need.ĭiscover the four types of breaking waves. So make sure your duck diving skills are up-to-scratch. The weight of a wave lip can be tremendous. Total weight? A solid 500 kilograms (1,100 pounds). A seismograph records P and S waves from an earthquake.

Typically the speed of the S wave is about 4.0 km s 1, and that of the P wave is 8.0 km s 1.

Unlike a gas, the earth can experience both transverse (S) and longitudinal (P) sound waves. That's the weight of 488 Volkswagen Beetles (1967 model)!Īnother example from the average surfer's perspective: imagine a 20-inch (50 centimeters) thick wave lip, only 3.2 feet wide, in a summer three-foot wave. Earthquakes generate sound waves inside the earth. If you want to get an overall weight for your specific wave, you can roughly memorize that a cubic meter of water (1,000 liters) weighs one metric tonne (1,000 kilograms).įor example, a 33-foot (10 meters) wave with a falling lip that is 66 feet (20 meters) wide will mean that, if you wipe out, you'll feel the equivalent of 410 tonnes (410,000 kilograms) over your body. Īlthough the human body will not literally "feel" those massive numbers, it will definitely feel something. The height, thickness, and width of the falling lip Ĥ. The salinity of the water (the world's average is 3.5 percent) Ģ. So let's do some math.Īccording to physicists, a breaking wave can apply a pressure of between 250-6,000 pounds per square foot (1,220-29,294 kilograms per square meter), depending on its height.Ĭan you handle numbers like this? There are many variables involved:ġ. But until then, those liquid curtains will not wait for a rider's lucky escape in order to fall over the flats. When a wave breaks, it loses part of its energy. Whether we get caught on the inside or miss an unexpected wave set, it's always tough to feel the weight of the salted water on our heads and back. The JMA is warning people in affected areas to be on their guard against landslides and flooding.How big is the largest wave you've ever surfed? Wave height is one thing the weight of waves is quite another. 1 up to 200 millimeters of rain is expected in the Izu Islands, 100 mm in the Tokai region and 80 mm in the Kanto region in eastern Japan, with more heavy rain in these areas and the Tohoku region the following day.

It cautioned people on the islands to refrain from unnecessarily going out, and to keep away from windows while indoors. The casualties and the economic damage were unprecedented.

The following day waves reaching 11 meters are forecast near the Izu Islands, while 6 to 8 meter waves are likely in other areas from western to northeastern Japan. 30, waves of up to 8 meters are expected around the Izu and Ogasawara islands south of the capital, while areas near the Okinawa, Kinki and Tokai regions from southern through central Japan are expected to see waves of up to 6 meters, the agency said. Winds of up to 25 m/s (90 kph) were forecast within 280 kilometers of the typhoon's center.Īfter approaching the Izu Islands, the typhoon is expected to pick up speed and move northeast to the east of Japan, before weakening into an extratropical cyclone by Oct. It had a central atmospheric pressure of 940 hectopascals, with a maximum wind speed near its center of 45 meters per second (162 kph) and a maximum wind gust speed of 65 m/s (234 kph). 30, the typhoon was located south of Japan and heading north-northeast at a speed of 25 kilometers per hour.
