Can tsunamis cause extensive flooding?
A tsunami’s long wavelength provides more momentum for inundation (flooding)
, so tsunamis often travel much farther inland than normal waves and are more destructive. A large tsunami can flood low-lying coastal areas more than a mile inland.
What can a tsunami cause?

loss of life and mass injuries
, other potential impacts include damage to and destruction of homes and businesses, ports and harbors, cultural resources, utilities, and critical infrastructure and facilities. There may be loss of access to basic services such as power, sewer, and water.
What are 5 effects of a tsunami?
Flood waters can pose health risks such as
contaminated water and food supplies
. Loss of shelter leaves people vulnerable to insect exposure, heat, and other environmental hazards. The majority of deaths associated with tsunamis are related to drownings, but traumatic injuries are also a primary concern.
What kind of damage is caused by tsunamis?
There are three factors of destructions from tsunamis:
inundation, wave impact on structures, and erosion
. Strong, tsunami-induced currents lead to the erosion of foundations and the collapse of bridges and seawalls. Flotation and drag forces move houses and overturn railroad cars.
How far can a tsunami flood?
Tsunami inundation is the horizontal, inland penetration of waves from the shoreline. Flooding can extend inland by

are called tsunamis.
Can tsunamis be good?
Perhaps
one of the most important positive effects of tsunamis is a redistribution of nutrients
. Tsunamis waves can lift up nutrient-rich sediment in estuaries and deltas and disperse it inland. In so doing, tsunamis help to spread nutrients in agricultural areas thus increasing the fertility of the soil.
What are the two 2 types of tsunami?
Tsunamis can occur when the earthquake is shallow-seated and strong enough to displace parts of the seabed and disturb the mass of water over it. There are two types of tsunami generation:
Local tsunami and Far Field or distant tsunami
.
What is the largest tsunami ever recorded?
Lituya Bay, Alaska, July 9, 1958
