In March 2011, a 9.0 earthquake hit offshore Japan. It triggered 200+ aftershocks as well a massive tsunami that hit other locations, including Hawaii.

What time did the tsunami in japan happen their time?
The earthquake giving rise to the tsunami occurred at 6,000 feet below sea level 80 miles from northern Japan and 240 miles from Tokyo. Seismic waves (sound traveling through the solid crust of the earth below the ocean floor) move at around 14,000 KM/hr or about 8,300 miles/hr. This means that the shock wave hit northern Japan (80 miles away) about 36 seconds after the quake. Japan knew, at least at this point, that a tsunami and probably a tidal wave were on their way and would hit the island nation within minutes. With the modern warning systems that are in place using both radio and sound equipment, Japan knew the moment the quake occurred that a tsunami was on its way.
A tsunami travels at about 600 mph which means that it would have reached northern Japan (80 miles away) about 8 minutes after the quake and Tokyo (240 miles away) in about 24 minutes. The actual time was probably slightly greater because a tsunami slows as it gets into shallow water so it was probably attenuated considerably from its spot of origin to the various points of contact with land thus increasing the time of travel somewhat.
How much of Japan was destroyed by the 2011 tsunami?
This city of Sendai was 80 miles (128 km) from epicenter of Earthquake.
Where in Japan was first hit by the Tsunami?
The first recorded tsunami that hit Japan occurred off the shore of the Kii Peninsula, Nankaido, Shikoku, Kii, and Awaji region. It has been estimated to be a magnitude 8.4

How far from the epicentre were the effects of japan's earthquake felt?
The USGS reported that the quake shifted portions of northeastern Japan by as much as 2.4 m (7.9 ft) closer to North America and made portions of Japan's landmass wider than before. This was a result of the 9.0 magnitude earthquake on March 11, 2011.
What damage did the tsunami japan 2011 cause?
One thing you could do is to improve buildings by making them triangle shape so that it has a wide surface area at the bottom or we can build one storied buildings so that they cant topple over. :)
How many people died in the worst earthquakes?
10 000 people died during the Mexico City earthquake, but there were also 50 000 injuries, and 250 000 people were made homeless.
Why did the Japan tsunami 2011 occur?
The earthquake that hit Japan was a magnitude of 8.8 which means the shaking triggered the waves of the ocean and made them grow larger and larger until it hit land. The tsunami was past 15 feet and killed many people.
How many people died during the Japanese earthquake?
The most recent count is over 2500 people, but there are still thousands missing.
Earthquakes happen all the time, but most are too small for anyone to get excited about. Since all geologists who record earthquakes operate mostly independently of those in another part of the world, there's no way at this time to tell which earthquake was technically last recorded.
The last major earthquake, however, was recorded October 12, 2008 at 20:55:42 UTC (Roughly equivalent to GMT). It was at latitude 20.060°S and longitude 64.940°W, which is in Chuquisaca, Bolivia. The quake originated 356.3 km (221.4 miles) below the surface of the Earth. No fatalities resulted from the 6.2 magnitude quake.

What is the place of origin of an earthquake?
If you want to know what the name is, it is called the epicenter.
If you want to know a location where all earthquakes originate, there isn't one. Earthquakes can occur along faultlines, or in the middle of a continent.
Where was the epicenter of this earthquake in Japan?
Yes, there was one in Niigata in 2004 or 2005. The emperor went to visit the victims.
What were the worst hit cities in the Japan 2011 earthquake?
Japan's most severe earthquake was on Friday 11th March 2011 which was an 8.9 magnitude, this happened because there are two plates which can push together right under Japan, but it was not just an earthquake, after the earthquake there was a tsunami which was 10m high.
How many buildings collapsed in the JAPAN earthquake?
There are reports from 7,400 - 125,000 buildings and homes damaged or destroyed depending on which news source you look at. Looks like the higher number is closer to the truth and will be while until all the numbers are in.
It's impossible to separate the damage of the March 11 magnitude 9.0 earthquake from the tsunami and hundreds of aftershocks that followed so the counts must include the total damage.
Which Japanese city was hit by and earthquake in 1995?
9.0. It was originally thought to be 8.9, but after official measurements came in, it was found to be 9.0.
This is 5th largest earthquake worldwide since the beginning of the 20th century.
How was the 1994 Northridge earthquake caused?
It is believed that movement on a blind thrust fault underneath the San Fernando Valley caused the Northridge earthquake.
The fault is known as 'blind' as it does not show any surface features, meaning that seismologists did not know the fault existed before the earthquake.
How did japan recover from the earthquake?
- Members of the Japan Maritime Self-Defense Force get ready to search for the victims of the March 11 tsunami.
- Fire crews, rescue teams, and volunteers are now digging through the wreckage left by the tsunami, as evacuation efforts continue around the Fukushima Daiichi Nuclear Power Station and engineers work to regain control of the failing reactor.
How many people died in the genocide in Rwanda?
An estimated 800,000 to 1 million people were killed during the genocide in Rwanda in 1994. The majority of victims were Tutsis, but moderate Hutus were also targeted by extremist Hutus. The genocide lasted approximately 100 days.
What are the benefits of Tsunami?
There are no positive effects of a tsunami. A tsunami does enormous damage to coastal areas, destroying buildings and killing people.
- it would clear a place for new buildings to be built.
- slows greenhouse emissions as factories are closed.
- reduces world population which is rising very fast.
Addenda
Any of the perceived benefits stated would be more than offset.
Clearing those buildings would almost certainly mean loss of life, home and workplace.
The greenhouse emissions produced replacing those factories and buildings would be greater than those the factories produced.
The deaths caused would have no measurable impact on the overall population rate of increase.

What was the cost of damage from the Japan earthquake in 2011?
The damage due to buildings and infrastructure in the March 2011 earthquake, tsunami, and resulting fires and explosions is estimated over $180 billion or 3 percent of Japan's annual economic output.
Other estimates up to US $300 billion for reconstruction excluding costs caused by the Fukushima nuclear accident.
What should Tokyo residents do to protect themselves if there is a meltdown at Fukushima Reactor?
Look to the related link below for additional precautions :
The following are guidelines for what you should do if a nuclear power plant emergency occurs. Keep a battery-powered radio with you at all times and listen to the radio for specific instructions. Close and lock doors and windows.
If you are told to evacuate:
- Keep car windows and vents closed; use re-circulating air.
If you are advised to remain indoors:
- Turn off the air conditioner, ventilation fans, furnace, and other air intakes.
- Go to a basement or other underground area, if possible.
- Do not use the telephone unless absolutely necessary.
If you expect you have been exposed to nuclear radiation:
- Change clothes and shoes.
- Put exposed clothing in a plastic bag.
- Seal the bag and place it out of the way.
- Take a thorough shower.
Keep food in covered containers or in the refrigerator. Food not previously covered should be washed before being put in to containers.
