6.5-magnitude
quake hits south of Fiji Islands -- USGS
SUVA,
March 26 (Xinhua) -- An earthquake measuring 6.5 on the Richter scale
jolted south of the Fiji Islands at 03:29:37 GMT on Wednesday, the
U.S. Geological Survey said.
The
epicenter, with a depth of 504.0 km, was initially determined to be
at 26.248 degrees south latitude and 179.363 degrees east longitude.

Experts
in Chile fear catastrophe, as 300 earthquakes strike in one week

2014 – CHILE – More
than 300 earthquakes have shaken Chile’s far-northern coast the
past week, keeping people on edge as scientists say there is no way
to tell if the unusual string of tremors is a harbinger of an
impending disaster.
The unnerving activity began with a strong
magnitude-6.7 quake on March 16 that caused more than 100,000 people
to briefly evacuate low-lying areas, although no tsunami materialized
and there was little physical damage from the shaking.
But the land
has not settled down. More than a dozen perceptible quakes were felt
in the city of Iquique just on Monday. “The situation is out of the
ordinary. There’s a mix of a string of tremors and their
aftershocks that make things more complex to evaluate,” Mario
Pardo, deputy head of the Universidad de Chile seismology center,
told the local newspaper La Tercera.
“We can’t rule out a larger
quake.” Chile is one of the world’s most earthquake-prone
countries. A magnitude-8.8 quake and ensuing tsunami in central Chile
in 2010 killed more than 500 people, destroyed 220,000 homes, and
washed away docks, riverfronts and seaside resorts.
The strongest
earthquake ever recorded on Earth also happened in Chile — a
magnitude-9.5 tremor in 1960 that killed more than 5,000 people.
The
last recorded big quake to hit the northern area around Iquique was a
devastating magnitude-8.3 in 1877. It unleashed a 24-meter-high
(nearly 80-foot-high) tsunami, causing major damage along the
Chile-Peru coast and fatalities as far away as Hawaii and Japan.
“The
latest string of quakes is noteworthy because the last one happened
in this seismic zone more than 130 years ago,” said Paulina
Gonzalez, an expert on seismic analysis at the Universidad de
Santiago. “It’s a zone where quakes should happen more often, and
they haven’t in a very long time.”
A major quake in the country’s
north would be a potential threat to the economy of Chile, which is
the world’s top copper producing nation. Most of the Chilean mining
industry is in the northern regions.
Chile’s worrisome seismic
activity can be traced to just off the country’s 4,000-kilometer
(2,500-mile) Pacific coast, where the Nazca tectonic plate plunges
beneath the South American plate, pushing the towering Andes
cordillera to ever-higher altitudes.
The 2010 quake released so much
energy it shortened the Earth’s day slightly by changing the
planet’s rotation. –NBC
