powerful quake, a 7.7 magnitude event that spawned a potent tsunami and has killed, at last count, more than 300 people.
Just last year
a powerful quake struck further north near the border with Peru, killing six people.
These all suggest the region has the potential to experience an even more
powerful quake.
In 1811 three
powerful quakes in a row — measuring approximately 7.5 to 8.3 on the Richter scale — ripped along the fault there, ringing church bells as far away as Boston.
It will extend the country's monitoring capabilities out to where the most
powerful quakes are born, buying perhaps another 10 precious seconds of warning before shaking starts or a tsunami floods the coast.
There will be more horror to come there and in other places prone to
powerful quakes.

quake was to the east of the more
powerful 7.8 magnitude earthquake on 25 April that killed more than 8000 people.
The team also analyzed how deep the earthquakes occur underground and concluded that as
quakes occur deeper, the rocks become stronger and the stress drop, or force behind the earthquakes, becomes more
powerful.

quake, which was the most
powerful ever recorded to hit Japan, may have occurred earlier than it might have otherwise, said Andreas Mavrommatis, a graduate student in Stanford's School of Earth Sciences.

quake, a magnitude 9.0 on the Richter scale.
The earthquake — estimated at magnitude 9.0 on the Richter scale — occurred in a total area much smaller than previous large earthquakes, such as the 8.8 Chilean earthquake last year, arguing that the slippage was much greater for the Japan
quake, one of the four most
powerful earthquakes on record.
Although it's impossible to pinpoint when such a
quake might occur, Floyd says this one could be
powerful — on the order of a magnitude 7 temblor, or stronger.
After investigating seismic waves observed during the earthquake in the Sea of Okhotsk, the researchers found the initial
quake triggered four other
powerful shocks, one of magnitude 7.8, one of magnitude 8.0 and two of magnitude 7.9.
Now, thanks to a newly available set of data collected in the aftermath of the disaster, the National Institute of Standards and Technology (NIST) is providing Chile and other
quake - prone areas worldwide with a
powerful tool toward becoming more resilient to future seismic events.
An investigation of the most
powerful earthquake ever recorded deep within the Earth suggests deep
quakes may be better at dissipating pent - up energy than similar
quakes near the surface, researchers say in a new study.
The recent earthquake swarm, beginning on March 24 and climaxed by a 4.9 magnitude tremor on Saturday, has produced no reports of injuries or severe damage but has rattled nerves in a region where Idaho's most
powerful known
quake, measured at 6.9, killed two children in 1983.
She discusses the mechanics of
quakes, the increase in human - induced tremors, the ways cities are safeguarding infrastructures (or not) against damage, and advances in technology that make these fleeting but
powerful phenomena easier to predict.
On March 11, a
powerful, magnitude 9.0
quake hit northeastern Japan, triggering a tsunami with 10 - meter - high waves that reached the U.S. west coast.
A «nightmare scenario», he says, is a massive tsunami following a
powerful but slow - rupturing
quake that causes little or no ground shaking, because people often then ignore any warnings.
A lighter roof that might fare better in a
quake may fly off in a storm with
powerful winds, like a tropical cyclone.
Just how
powerful is
Quake now?

The government's decision to pursue major publishers on antitrust charges has put the Internet retailer Amazon in a
powerful position: the nation's largest bookseller may now get to decide how much an e-book will cost, and the book world is
quaking over the potential consequences.

Obviously,
Quake has a very
powerful set of tools, no question about it, but this is really a next - generation toolset with the mesh editor and the lush graphical content and the sheer density of the natural settings and the lighting options and the weather options.
More than a thousand schools in Oregon are ready to fall in a
quake that could be 32 times more
powerful than the one that shattered eastern Sichuan province.
One disturbing aspect of the disaster is that a
powerful 7.2 magnitude earthquake in nearly the same location on March 9 — almost assuredly related, in terms of geophysics, to the super
quake overnight — can only be recognized as a foreshock after the fact.
The most
powerful earthquake on record was 9.5
quake which occurred in Chile in 1960.
In addition, a
quake that struck the New Madrid Fault in Missouri in December 1811 was so
