The shindo scale ranges from shindo one, a slight earthquake felt only by people who are not moving, to shindo seven, a severe earthquake. Shindo two to four are still minor earthquakes that do not cause damage, while objects start to fall at shindo five, and heavier damage occurs at shindo six and seven. Every household should keep a survival kit with a flashlight, a radio, a first aid kit and enough food and water to last for a few days.
Avoid placing heavy objects in places where they could easily fall during an earthquake and cause injury or block exits.
Have a fire extinguisher. Familiarize yourself with the designated evacuation area in your neighborhood. Falling objects, toppling furniture and panic present the greatest dangers during an earthquake.
Try to protect yourself under a table or doorway. Do not run outside, and try to remain as calm as possible. If you are in the streets, try to find protection from glass and other objects that may fall from surrounding buildings. After a strong earthquake, turn off ovens, stoves and the main gas valve.

Some of the most destructive earthquakes occurred almost a century ago, while others happened in the recent past.
On September 1st, , an earthquake with a magnitude of 7. The aftermath also triggered a massive city fire, and casualties rose to over , The earthquake not only led to major fires in the metropolitan region but also resulted in a meter-high tsunami wave that hit Sagami Bay. The bay, located in the south of Kanagawa Prefecture, was also the hypocenter of the earthquake, and the landmasses of the bay shifted two meters upwards during the quake. On January 17th, , an earthquake with a magnitude of 7.
With a magnitude of 9. The ocean megathrust earthquake occurred off the Sanriku coast by Miyagi Prefecture, about km east of Sendai and km northeast of Tokyo.
According to the current status of June , 15, people died in the triple disaster, and 2, are still missing today. The destruction and nuclear disaster forced almost half a million people to leave their apartments and houses. Just as the Kanto and Kobe Earthquakes had, the Tohoku earthquake altered the plate tectonics.
The main island of Honshu shifted 2. In the days and weeks after the disaster, around earthquakes with a magnitude of 5. Most modern Japanese buildings have earthquake-proof construction of cushioned pillars anchored in massive concrete foundations. It will ensure that you will get through unscathed during such an event in Japan. And finally, the earthquake has to be shallow.
Today's earthquake was shallow — about 6 miles 10 km underground — but the epicenter was on land, meaning there aren't likely to be any dangerous tsunamis as a result, Caruso said. Given said he hasn't seen many damage reports yet, but Japanese authorities and scientists at the USGS will be monitoring the area for potentially dangerous aftershocks, which are smaller quakes that follow the largest event in a series and that generally decrease in strength.
Additional damage can be expected. No one can predict that. Follow Denise Chow on Twitter denisechow. In Japan, you will sometimes hear sudden beeping noise interrupting your TV program and words flashing across the top of the screen - that is a public announcement of the occurrence and magnitude of any earthquake or natural disaster that just occurred in Japan.
At the same time, an alarm, warning or evacuation directive will be declared if there is a risk of tsunami. Particularly in order for the earthquake alert to be useful to you, it may be helpful to understand some basic earthquake indicators.
However, before getting into terms like "magnitude" and "seismic scale," let's explore the relationship between Japan and earthquakes--so that you can at least understand a bit about what's happening under your feet first. There are actually well-documented geological reasons why Japan is so earthquake-prone. An earthquake occurs due to the stresses caused by the movements of tectonic plates that comprise the earth.
Japan and earthquakes go hand in hand due to the country's position along the "Pacific Ring of Fire," where it lies across three tectonic plates, including the Pacific Plate under the Pacific Ocean and the Philippine Sea Plate. As earthquakes can also occur within a tectonic plate, thus occurring on land rather than in the sea and radiating outwards, it is it is foreseeable that a major quake may strike directly under Tokyo or another large urban city that is not accustomed to earthquakes or seismically retrofitted.
Fortunately, though, many buildings are outfitted to better withstand earthquakes. Some are actually designed with the top part able to move with a given earthquake as it happens, while others are meant to actually absorb it and stay steadfastly grounded.
Such innovative technology shows that the relationship between Japan and earthquakes--although certainly frightening at times--has produced some useful technology that can help save lives. The intensity of an earthquake is measured using the term "magnitude", while the impact of the earthquake that can be felt is measured on the "seismic intensity scale. Of course, as you will see below, seismic activity in Japan has been known to go above even the highest level on the scale.
Actual effects vary depending on various factors including distance from the epicenter and the geological condition of the area. With a magnitude of 9, the Great Tohoku Earthquake that originated off the coast of Japan was the most powerful earthquake ever to have struck the country and the fourth strongest earthquake in the world since record-keeping began in As Japan earthquake information available through smartphone apps, the internet and other media will tell you, however, many much smaller tremors and quakes occur daily and even hourly without any destructive effects.
