Bear in mind that it is not just the Richter scale measurement which determines the severity of a tsunami which results from an earthquake; the location of the earthquake is also relevant. And inland earthquake does not produce the same tsunami as an underwater earthquake. That said, 8.3 is an extremely powerful earthquake which could produce a tsunami that would travel for thousands of miles and cause immense dammage over a very wide area.
No because the New Madrid quakes occurred far inland, so therefore no tsunami was generated by the plate tectonics under a large body of water as is the mechanism for most earthquake-generated tsunamis. However, the New Madrid fault earthquake did cause the Mississippi river to flow backwards.
Most of the world's earthquakes occur along tectonic plate boundaries, particularly in regions known as the "Ring of Fire," which encircles the Pacific Ocean. This area is characterized by high seismic activity due to the movement and interaction of several tectonic plates. Additionally, earthquakes can occur inland along fault lines, but coastal regions and areas near plate boundaries experience the highest frequency of seismic events.
It is because, the earthquake that broke of the coast of sendai happened under the sea and the type of the earthquake was a destructive.Meaning it moved the plates backwards and forwards under the sea bed causing the sea above it to violently move back and forwards creating dangerousley high and powerful waves(4-10M) to reach the coast of sendai and sweep miles through the inland areas.
1. they shake the ground ... up and down or sidewise2. the relieve the internal pressure that builds up as the tectonic plates move.Here effects of an earthquakes: Tsunami A tsunami is a series of huge waves caused by an earthquake under the sea. These waves travel at about 800 km per hour. Before a tsunami reaches the shore, it slows down. The water along the shore recedes as if there were a very low tide. When the water comes back, the height of its waves may reach up to 30 m. It can destroy houses, crops and people as it goes inland and then back to the sea. Seiche An underwater earthquake can also generate a big wave in an enclosed body of water like a lake or a pond. This big wave which can be about 3 m high is called a seiche. A seiche can cause immediate flooding of areas near the lake. Faulting Strong earthquakes can also change the earth's surface. Cracks may form on the crust. When this happens, part of the crust may be displaced horizontally or vertically. In some cases, a section of the crust is raised above the section near it. Shallow gaps may also be formed on the crudt. Landslide Some earthquakes affect hilly or mountainous areas. Continiuous shaking of the ground changes the psition of some rocks or dislodges them. When these rocks roll downhill, they can destroy houses on their path or kill people. Sand Blows When an earthquake occurs in a place where there is much ground water, water is forced out of the ground in the form of an earthquake fountain. When this happens, sand is forced out and deposited on the ground in the form of volcanolike mounds. These are called sand blows. Fire Earthquakes can also cause fire. This happens when electric wires are destroyed and electric posts are upturned. Fire can easily spread to residential houses and other buildings.
Intraplate earthquakes occur farther inland than other earthquakes. These earthquakes occur within a tectonic plate, away from plate boundaries where most earthquakes typically occur. Intraplate earthquakes can be caused by ancient faults or stress within the plate itself.
Earthquakes can occur in Nevada, which is not far from earthquake-prone California. Tornadoes occur in Nevada on occasion, but they are rare and usually weak. Nevada is too dry and too far inland to get hurricanes.
the weather is usually cooler near the coast because of the ocean. the ocean air is cooler than farther inland.
farther inland :)
An earthquake on land can cause extensive damage and loss of life as buildings collapse. If the earthquake happens under the sea, a tsunami can form and destroy coastal areas and some way inland.
Live farther inland.
The Christchurch earthquake in 2011 did not generate a tsunami due to its location on a strike-slip fault, where the movement is horizontal rather than vertical. Tsunamis are typically caused by vertical displacement of the seafloor, which can occur in subduction zone earthquakes or underwater landslides.
Japan was very close to the epicenter of the earthquake; many of their buildings were damaged by the earthquake itself. Parts of the coast line were depressed and indented. Japan is an island nation, and much of the country is at or below sea level anyway. Because of this, the tsunami was able flood farther inland and because of the land features that were altered by the earthquake, the water did not recede.

Yes, earthquakes do occur in the central portion of the US, although they are less frequent and less intense compared to regions like the west coast. The New Madrid Seismic Zone, located in the central US near the Mississippi River, is known for its historic earthquake activity.
it cant there are no volcanoes or earthquakes in florida i should know i lived there
The earthquake that caused the tsunami might be so powerful that the force of the quake travels under the sea to the nearest coastline and causes the water near the shore to head inland with speed and power, destroying all it's path of destruction.
