And we have seen quantum improvements in seismology as well as in directional and horizontal drilling, under-sea pipeline construction to name just a few.
His phobia about earthquakes-how can they call seismology a science?
It's a freeware game about reflection seismology, which is imaging underground structures by sending soundwaves into the ground and interpreting the echos.
The ESA / NASA mission SOHO, observing the Sun since 1995, has paved the way for stellar seismology, which is the approach now extended by COROT to the probing of other stars.
Because of the inconvenient ice cover, most Antarctic geology can be studied only by remote-sensing methods such as seismology, which involves setting off explosions, bouncing the soundwaves down through the ice to the earth's crust and recording them on their way back up.
"It seems quite likely that they are related," said Brian Baptie, the survey's head of seismology.
Sergio Barrientos, director of the seismology office at the University of Chile, said Sunday's temblor was itself an aftershock of last year's mega-quake.
September's earthquake in Christchurch was nearly 10 times stronger than Tuesday's tremor, but made less of an impact because it struck further from the city, says Adam Pascale , head of seismology at Environmental Systems and Services, a private seismic observatory based in the Australian city of Melbourne.
"Damage is possible in areas hit by at least intensity 5 and if the buildings are structurally weak," said Renato Solidum, head of the volcanology and seismology institute.
But the grinding plates of the earth move in mysterious ways, and Friday the largest recorded earthquake in Japan's history - a stunning magnitude 8.9 on the short list of most violent events since the dawn of seismology - hit about 230 miles northeast of Tokyo, generating a tsunami that within minutes socked the coast of Honshu, Japan's largest island.
