Now Zhigang Peng, associate professor in Georgia Tech's School of Earth and Atmospheric Scienceshas converted the earthquake's seismic waves into audio files. The results allow experts and general audiences to "hear" what the quake sounded like as it moved through the earth and around the globe.
Audiences can relate the earthquake signals to familiar sounds such as thunder, popcorn popping and fireworks. The different sounds can help explain various aspects of the earthquake sequence, including the mainshock and nearby aftershocks.
What have scientists learned about its cause and consequences?
For example, this measurement was taken near the coastline of Japan between Fukushima the nuclear reactor site and Tokyo. The initial blast of sound is the 9. As the earth's plates slipped dozens of meters into new positions, aftershocks occured. They are indicated by "pop" noises immediately following the mainshock sound.
These plate adjustments will likely continue for years.
However, these historical records cannot quantify the height or inundation area of the Jogan tsunami. Final Wars and 's Godzilla. We apologise for any confusion regarding this film.
As the waves from the earthquake moved through the earth, they also triggered new earthquakes thousands of miles away. In this example, taken from measurements in California, the quake created subtle movements deep in the San Andreas Fault. The initial noise, which sounds like distant thunder, corresponds with the Japanese mainshock.
Afterwards, a continuous high-pitch sound, similar to rainfall that turns on and off, represents induced tremor activity at the fault. The animations not only help scientists explain the concept of distant triggering to general audiences, but also provides a useful tool for researchers to better identify and understand such seismic signals in other regions.
This third recording was taken about 90 miles from the Japanese earthquake's epicenter.
Strange Sounds Around The World
There are two distinct sound waves, both are caused by the mainshock. A "pop" is heard 90 seconds in actual time after the main event.

This pop wasn't recorded at any other nearby stations, leading Peng to believe that either the ground shifted immediately under the measuring station, or the hill slope where the station sits helped to amplify the shaking. It was the strongest reading he found - a ground acceleration of nearly three g. The human ear is able to hear sounds for frequencies between 20 Hz and 20 kHz, a range on the high end for earthquake signals recorded by seismometers.
Peng, graduate student Chastity Aiken and other collaborators in the U. The process also allows audiences to hear data recorded over minutes or hours in a matter of seconds. In this set of before and after pictures, scenes of the devastation are juxtaposed with images of the same spots, cleaned of debris and effectively reclaimed by the Japanese people.
A surge of water from the tsunami caused by the quake knocked out power at the coastal Fukushima plant, leading to the worst nuclear disaster since Chernobyl. Tens of thousands have had to leave the area, and it's unclear whether some will ever be able to move back.
Volunteer and governmental organisations have worked tirelessly to restore the country, and as these pictures reveal, the results show for themselves. Get top stories and blog posts emailed to me each day. Newsletters may offer personalized content or advertisements. Sara C Nelson Eureka!
Integrated GPS measurements allow accurate georeferencing. Green functions are computed for elementary waves of Gaussian shape and grid spacing which is below the resolution of the data. The hail started around 4:
