Large earthquake strikes off coast of Chile, tsunami warnings issued

An 8.2-magnitude earthquake struck Tuesday evening off the northern coast of Chile, prompting worries of a tsunami hitting the country and its northern neighbor, Peru.

The large quake struck just before 9 p.m. local time about 60 miles off the coast of Iquique, Chile.

Two people died and three more were in serious condition, Iquique’s governor told a local radio station, according to Reuters.

Buildings were evacuated after the earthquake. Chilean authorities said they were evacuating all coastal areas, but reported no casualties or significant damage.
The quake also allowed 300 inmates to escape a women’s prison in Iquique and power outages were reportedly widespread.

Landslides blocked roads, an airport was damaged and fires were reported in downtown Iquique.

The Chilean government reported no major damage hours after the tremor, which produced aftershocks of magnitude 6.2 and 5.5.
The tremor was also felt in Bolivia and Peru, and 6-foot waves reportedly hit the Chilean coast.

The quake was only 6.2 miles below the seabed, meaning it felt stronger because it was so shallow.

'This one was big but it's not the Big One'

An 8.2-magnitude earthquake struck off the coast of northern Chile Tuesday night, triggering small landslides, setting off a tsunami and killing at least five people.

But geologists say an even larger quake in the region is lurking."This magnitude 8.2 is not the large earthquake that we were expecting in this area," said Mark Simons, a geophysicist at Caltech in Pasadena, California. "We're expecting a potentially even larger earthquake." It could be tomorrow. Or it could be 50 years. "We do not know when it's going to occur," he said.

Here's why:
Chile sits on an arc of volcanos and fault lines circling the Pacific Ocean known as the "Ring of Fire." This area sees frequent earthquakes and volcanic eruptions. The country itself has seen no shortage of seismic activity in recent years. Since 1973, Chile has had more than a dozen quakes of magnitude-7.0 and above. Powerful earthquake strikes off Chile, triggers tsunami
In 2010, about 500 people died when an 8.8-magnitude earthquake hit. That quake was so violent, it moved one whole city about 10 feet west.

Simons says Tuesday's quake is of interest because the fault line along Chile's coast has constantly shifted during the last 140 years. In recent weeks, this area has seen a cluster of activity-- something like 50 to 100 smaller quakes. Then, late last month, a 6.7 and a 6.1 magnitude quake struck.

When quakes happen, the surface ruptures. The two sides of the fault slip past each other.
But the area to the north and south of Tuesday's quake "did not rupture in this event," Simons said. And it's "still an area that hasn't ruptured in 140-odd years."

Given that it's an area of frequent quakes, and frequent ruptures, it may only be a matter of time.
"We expect another 8.8-8.9 earthquake here sometime in the future," Simons said.
The good news? "It may not occur for many, many years."

Nieuwe beving treft Chili
De tsunamiwaarschuwing voor Chili is ingetrokken. Volgens de autoriteiten is het gevaar van een vloedgolf geweken en kunnen mensen teruggaan naar huis.

Vannacht was er opnieuw een beving in de oceaan voor Chili. De schok had een kracht van 7,8 op de schaal van Richter.

Mensen in de noordelijke kustgebieden werden opgeroepen om naar hoger gelegen plekken te gaan. Ook president Bachelet, die vanwege de aardbeving van maandagavond in het gebied overnachtte, gaf daaraan gehoor.

Zeebeving
Het noorden van Chili werd maandagavond opgeschrikt door een zeebeving met een kracht van 8,2 op de schaal van Richter. De beving kostte zes mensen het leven.

Ook na die beving werd een tsunamiwaarschuwing afgegeven. Golven van zo'n twee meter hoog bereikten uiteindelijk de kust, maar richtten geen verdere schade aan. Wel werden duizenden mensen in veiligheid gebracht.
