School Notice in the figure how it forms the tsunami: wave velocity is higher in deeper waters ... And lower in profile ... the bottom in the shallow Sea The speed of the tsunami is reduced as it draws near to the beach (less depth). See the figure "How is a tsunami," the last waves, have greater speed, piling up the waves that are in front, increasing the height and breadth of these. Thus, as the wave approaches ground, its frequency and its height increases and speed decreases. See more details in the "Waves". Table 2 Waves You must have realized that natural phenomena of origin in internal geodynamics are propagated by waves: seismic waves of earthquakes, the tsunami waves. Just remember, the waves are mechanical in question because propagate in a material medium (water). If a wave which propagates in a medium, is the surface of another medium can undergo reflection, absorption and / or refraction. The latter is the case tsunami. The illustration shows the parameters that characterize a wave: length and wave amplitude (crest, valley and height), and the oscillation frequency and propagation speed. Note that the amplitude is measured from sea level (the case of ocean waves) and the height is the vertical distance between the crest of a wave and the wave valley adjacent.

Although tsunamis occur most frequently in the Pacific Ocean, can occur anywhere. There are many ancient descriptions of sudden and catastrophic waves, particularly in the region of the Mediterranean Sea. Thousands of Portuguese who survived the great earthquake of Lisbon in 1755 were killed by a tsunami that followed a few minutes later. Before the big wave hit the coast, the harbor waters retreated, revealing lost cargo and abandoned shipwrecks. Environmental Dimension of Geographical Space

Škola Obavijest na slici kako to čini tsunamija: val brzina je veća u dubljim vodama ... I niže u profilu ... dno u plitkim More Brzina od tsunamija je smanjena jer se približava plaže (manje dubine). Vidi figura "Kako je tsunami," posljednji valovi, ima veću brzinu, gomilaju valove koji su ispred, povećavajući visinu i širinu tih. Dakle, kao val približava zemlju, svoju frekvenciju i njezine visine povećava i brzina smanjuje. Pogledajte više detalja u "Valovi". Tablica 2 Valovi Morate imati shvatio da su prirodni fenomeni podrijetla u unutarnjim geodinamici razmnožava vala: seizmičkih valova potresa, tsunamija valova. Samo zapamtite, valovi su mehanički u pitanje jer propagirati u materijalnom mediju (voda). Ako je val koji se širi u mediju, je površina neki drugi medij, može proći razmišljanje, apsorpciju i / ili loma. Potonji je slučaj tsunamija. Slika prikazuje parametre koji karakteriziraju val: val duljine i amplitude (grb, dolina i visina), i oscilacija frekvencije i brzine prostiranja. Imajte na umu da je amplituda se mjeri na morskoj razini (slučaj valova oceana), a visina je okomita udaljenost između brijeg vala i doline vala susjedna.

Iako tsunami najčešće se javljaju u Tihom oceanu, može se pojaviti bilo gdje. Postoje mnogi drevni opisi naglih i katastrofalan valova, osobito u području Sredozemnog mora. Tisuće Portugalaca koji su preživjeli veliki potres u Lisabonu 1755 ubijeno tsunami koji je uslijedio nakon nekoliko minuta kasnije. Prije veliki val pogodio obalu, luka vode povukla, otkrivajući izgubio tereta i napuštenih brodskih olupina. okoliša Dimenzija zemljopisnim
