A submarine, undersea, or underwater earthquake is an earthquake that occurs underwater at the bottom of a body of water, especially an ocean. They are the leading cause of tsunamis. The magnitude can be measured scientifically by the use of either the Richter scale or the Mercalli scale. Understanding plate tectonics helps to explain the cause of submarine earthquakes.

  • A submarine, undersea, or underwater earthquake is an earthquake that occurs underwater at the bottom of a body of water, especially an ocean. They are the leading cause of tsunamis. The magnitude can be measured scientifically by the use of either the Richter scale or the Mercalli scale. Understanding plate tectonics helps to explain the cause of submarine earthquakes. The Earth's surface or lithosphere comprises tectonic plates which average approximately 50 miles in thickness, and are continuously moving very slowly upon a bed of magma in the asthenosphere and inner mantle. The plates converge upon one another, and one subducts below the other, or, where there is only shear stress, move horizontally past each other. Little movements called fault creep are minor and not measurable. The plates meet with each other, and if rough spots cause the movement to stop at the edges, the motion of the plates continue. When the rough spots can no longer hold, the sudden release of the built-up motion releases, and the sudden movement under the sea floor causes a submarine earthquake. This area of slippage both horizontally and vertically is called the epicenter, and has the highest magnitude, and causes the greatest damage. As with a continental earthquake the severity of the damage is not often caused by the earthquake at the rift zone, but rather by events which are triggered by the earthquake. Where a continental earthquake will cause damage and loss of life on land from fires, damaged structures, and flying objects; a submarine earthquake alters the sea bed floor, resulting in a series of waves, and depending on the length and magnitude of the earthquake, huge tidal waves and tsunamis, which bear down on coastal cities causing property damages and loss of life. Submarine earthquakes can also damage submarine communications cables, leading to widespread disruption of the Internet and international telephone network in those areas. This is particularly common in Asia, where many submarine links cross submarine earthquake zones such as the Pacific Ring of Fire.
  • Een zeebeving is een aardbeving waarvan het epicentrum op zee ligt. Hierdoor kan een vloedgolf ontstaan die tot overstromingen kan leiden in landen rondom het epicentrum. Een zeebeving is ten allen tijde een gevolg van een aardbeving. Een zeebeving kan een tsunami veroorzaken doordat een van de aardschollen plotseling omhoog of omlaag gaat. Op open zee zijn deze golven vaker niet hoger dan een paar centimeter, als zo'n golf echter de kustlijn bereikt en het ondieper wordt, kunnen die golven soms wel een tiental meters hoog worden.
  • O Predefinição:PEPB (conhecido popularmente como maremoto) é ocasionado pelo deslocamento das placas tectónicas, que são blocos em que a crosta terrestre está dividida. Os grandes sismos produzem ondas gigantescas chamadas tsunamis que se deslocam por quilómetros a alta velocidade. Às vezes essas ondas atingem ilhas e costas dos continentes, provocando destruição material e mortes nos locais habitados. As ondas originadas podem atingir mais de 30 metros de altura.
  • Маремо́то (от итал. maremoto ← mare + terremoto) — подводное землетрясение, вызывающее приливные волны и цунами. Маремото является феноменом, когда огромный объём воды смещается в вертикальном направлении. Предполагается, что 90 % этих явлений вызывается землетрясениями, и в этом случае они более точно называются тектоническими цунами. Энергия цунами зависит от их высоты (амплитуды волнового колебания) и их скорости. Общая разрушительная энергия цунами в плоской прибрежной зоне зависит также от числа волн (в последнем цунами в Индийском океане было 7 волн).
