Why did the Japan earthquake happen?
Japan is situated on four tectonic plates. The earthquake was the result of movement between two of the plates. The Pacific Plate and the Eurasian Plate.
Was this answer useful?
Thanks for the feedback!
They occur because of the techtonic plates in the Pacific and the Philippines. because the plates move every couple of years, they say it moves as fast as your fingernails, t…hat seems slowley to us but it is actually quite fast there. Also, when the plates press together and rub they can slip and form a strike-slip fault, with this can come tsunamis, and many other natural disasters.
The event was recorded on Friday, March 11, 2011 at 02:46:23 PM local time.
Earthquakes happen all the time. It's just about whether we feel it or not and how much we feel it. Therefore it's impossible to put a number on it.
All countries along the pacific tectonic plate [any country that borders the pacific ocean] are along the most active source of volcano activity and tectonic movement, however… in Japan's case along with most of south east Asia the two tectonic plates there are always under pressure from the fact that the pacific plate is always expanding, and it expands and grows from a fault somewhat close to Japan.
Japan. It has a lot of earthquakes, and is one of the most affected areas in the world. Because of their technology level (compared to countries like Indonesia and Fiji), Japa…n is the country with the most earthquakes reported each year. Though, that doesn't mean it's the country with the most earthquakes. But it certainly has more earthquakes than California.
There are building construction techniques used in Japan (and many other countries, including the USA) that are designed to minimize earthquake damage as much as possible. Mos…t of them have been shown to be effective.
There are many earthquakes in Japan, but the most recent one of note is the magnitude 9.0 earthquake that occurred on March 11, 2011 in the depths of the Pacific Ocean near th…e northeast coast of Honshu, Japan, about 130 kilometers (80 miles) east of the city of Sendai and triggered the massive tsunami that devastated the coast of Japan.
because it was devastating and lots of people died (probably) (hopefully not)
The Earth is covered with tectonic "plates", partial shells of rock. As heat is distributed from the Earth's core, it moves the plates around very slowly. But the plates stick… together around the edges, and as forces build up, the plates jerk or lurch across the Earth's mantle. We call this an "earthquake". The Japan plate touches the Pacific plate, and over the last 100 years or so, considerable stress built up along the boundaries. On March 11, 2011, much of the stress was relieved as the Pacific plate rode underneath the Japan plate. The movement of the Earth was significant, but the jolt caused a movement in the ocean, called a "tsunami". The tsunami is what caused most of the damage and deaths. As of March 20, 2011, the official death toll is over 8,000, but there are about 15,000 people still missing. Most areas of the Earth are subject to occasional earthquakes, especially around the edges of the Pacific plate. Because of the frequency of earthquakes and volcanoes, this is sometimes called the "Ring of Fire". Within the past year, in addition to the March 11 quake, major earthquakes have occurred in New Zealand and Chile.
The magnitude 9.0 earthquake that hit Japan in 2011 occurred at 14:46 JST (05:46 UTC) on Friday 11 March 2011. You can see what time that was in your area in the r…elated links below.
Yes, it did tilt the earth slightly. It may have also shortened the length of Earth's days by about 1.26 microseconds. A microsecond is one-millionth of a second. ~ Look to …the related link below .
Because the Pacific Plate is moving to the northwest, and Japan, New Zealand, Alaska, and California are all located on the boundary of that plate. Haiti and Chili are on the …boundaries of other plates, and when one moves, it effects the one next to it. My bet is on Anchorage Alaska for the next big quake. Another Answer: It's because on plate banged into another one which made it go down and then it flicked up causing an earthquake and a tsunami.
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.
About 275 that can be felt...
most likely, yes Well - another earthquake can certainly happen - but - being linguistically precise and picky, another earthquake can't happen AGAIN because it has not happen…ed yet. Not sure if this was the questioner's intent, but an interesting riddle none the less.
a old lady fell in water thats what caussed the earthquake
Because Japan is located on a huge tectonic plate of the earth's crust. When these plates collide or slide up on top of each other it creates an earthquake. London is probab…ly located in the middle of one of these plates.If you want to find out more on Japanese earthquakes search "the ring of fire" on google.
