8.2 Strikes No. Chile.....Small Tsunami....Foreshock?


Recommended Posts

There were numerous foreshocks and quakes in the weeks prior.

The largest quake ever reported in that area was a 9.5 about 35 yrs ago which killed over 500 and there was considerable coastal subsidence.

SANTIAGO, Chile (AP) — A powerful magnitude-8.2 earthquake struck off Chile’s northern coast Tuesday night, and officials ordered an evacuation of coastal areas before an expected tsunami. There were no immediate reports of injuries or damage from the tremor, which also shook buildings in parts of nearby Peru and Bolivia.

 

The U.S. Geological Survey initially reported the quake at 8.0, but later upgraded the magnitude. It said the quake struck 61 miles (99 kilometers) northwest of the Chilean city of Iquique at 8:46 p.m., hitting a region that has been rocked by numerous quakes over the past two weeks.

 

Waves measuring almost 2 meters (6 1/2 feet) already were striking cities on the coast, and authorities said a tsunami was expected to come ashore later. Local TV images showed residents evacuating calmly.

While Tuesday's earthquake in Chile was large by any measure, seismologists remain concerned it could have been a foreshock to a much larger quake in this region – a section of plate boundary that hasn't seen a major rupture in 137 years.

 

 

The temblor Tuesday struck a small segment of the gap. If the entire segment were to snap all at once, it would produce a much bigger quake, he explains.

 

Indeed, "one of the possible scenarios that we're monitoring right now is that it is still possible that the earthquake we had last night is actually a foreshock to a much bigger earthquake," he says. "For the sake of our Chilean friends, we hope that it doesn't happen."

Aftershock

 

M7.6 - 19km S of Iquique, Chile

2014-04-03 02:43:17 UTC

 

 

IQUIQUE, Chile (AP) — A powerful 7.6-magnitude aftershock hit Chile's far-northern coast late Wednesday night, shaking the same area where a magnitude-8.2 earthquake hit just a day before causing some damage and six deaths.

Chile's Emergency Office and navy issued a tsunami alert and ordered a precautionary evacuation of low-lying areas on the northern coast, meaning many people could be spending another sleepless night away from their homes.
