Satellites to predict earthquakes, claim scientists
In what may help save thousands of lives worldwide, scientists have launched a project which they claim could predict exactly when and where earthquakes will happen.
A team of British and Russian scientists has signed an agreement to work together on the project in Moscow.
The TwinSat project involves the launch of two satellites -- one of which the scientists say is about the size of an old TV set and the other smaller than a shoebox -- which will orbit the Earth a few hundred miles apart, 'The Independent' reported.
The two linked satellites will monitor zones with high seismic and volcanic activity, such as Iceland and the Kamchatka Peninsula in the far east of Russia. Data from the satellites will be collated with data from the ground as the scientists try to understand what natural warnings are given prior to earthquakes.
"As stress builds up in the Earth prior to an earthquake, subtle electromagnetic signals are released that can be read from the upper atmosphere.
"We want to try to work out how these signals differ from all the other things that are present at any given time," said Prof Alan Smith of University College London who launched the project.
Prof Vitaly Chmyrev of the Institute of Physics of the Earth in Moscow, one of the Russian partners, said the possibilities for progress in quake research were exciting and the project will "benefit both Russian and British science in addition to making the Earth a safer place".
