Tsunamis can be Detected in 8.5 Minutes

Using a special algorithm, the system conclude whether the tsunami will come or not.

Seismologists to develop a system that can be used to detect the occurrence of tsunamis within minutes after the earthquake.
The system, called by the name RTerg, is expected to help reduce the number of victims by providing more time for residents to evacuate to safety.
Technology development conducted by researchers from the Georgia Institute of Technology was published in the journal Geophysical Research Letters.
"We developed a system in real time successfully identified the 7.8-scale earthquake in the Sumatra earthquake tsunami in 2010 as a rare and potentially damaging," said Andrew Newman, a researcher from the School of Earth and Atmospheric Sciences, as quoted by Science Daily, Tuesday, 22 March 2011.
By using this system, according to Newman, seismologists can warn the local population and minimize the death toll from the tsunami.
For information, rather than ordinary earthquakes that took place more quickly and directly to shake, quake tsunamis generally occur slowly, lasts longer, and do not release much energy.
To find out whether there will be a tsunami, RTerg be sent a notification from the nearest tsunami warning centers that an earthquake has occurred.
Notification that provides information about the location, depth, and approximate magnitude quake. If the detected level of 6.5 or higher, the system only takes about 1 minute to extract data from about 150 earthquake detection stations around the world.
After the data collected, the system will use algorithms to measure the shocks and see if there is growth and rising energy ascertain whether it is an earthquake-tsunami earthquake or not.
When detect tsunamis in the Sumatra earthquake in 2010, RTerg system takes 8 minutes 30 seconds to ensure that the tsunami would occur.
This system would then send the notification after the counting is completed.
"Most of the tsunami arrived on the coast about 30 to 40 minutes after the shock occurs. So, we've got about 20 to 30 minutes to disseminate the information to relevant agencies, "said Newman.
Currently, Newman explained, the institute is trying to slash the time needed to generate tsunami information system. "We will also rewrite the algorithms required for this system can be installed around the center monitors all over the world," he said.
