Chile's northern coast has been hit by more than 300 earthquakes in the past week in what seismologists warned Tuesday could be the precursor to a long-overdue disaster.
Most of these quakes have been too small to be felt on land, but people living near the city of Iquique have experienced the rumbling of up to a dozen tremors per day.
Experts analyzing this flood of data are worried the increased seismic activity could be a sign the region is about to experience its first devastating quake in 137 years. The last event, a magnitude-8.5 quake in 1877, killed thousands of people and created a deadly tsunami that reached Hawaii and Japan.
"It is very unusual activity and we are trying to find out what is causing it," said Mario Pardo, deputy head of the seismology center at the University of Chile.
"We usually get around 10 earthquakes per day in this area [many of them very small], but now we have been getting up to 100 per day," he told NBC News via telephone from the country's capital Tuesday.
Pardo told NBC News that seismologists are particularly concerned about this cluster of quakes because press reports following the 1877 event said there was a similar "swarm" of tremors beforehand.
"We have been waiting for a big one in this area for some time - this is a place where we are expecting an earthquake of over 8.5 magnitude," he said.
Paulina Gonzalez, an expert at the University of Santiago, backed up this analysis. "The latest string of quakes is noteworthy because the last one happened in this seismic zone more than 130 years ago. It's a zone where quakes should happen more often, and they haven’t in a very long time," she told The Associated Press.

Tsunami waves up to 1.8 meters high struck the coast of Chile after the U.S. Geological Survey reported a magnitude 8.2 earthquake about 95 kilometers off the country’s northern coast.
The Chilean emergency services said they had not received any reports of major damage. A tsunami warning was issued for the entire Chilean coast, Peru and Ecuador after the quake hit around 9 p.m. local time.
The temblor cut power in parts of the country, according to TVN, the Chilean national broadcaster. The station reported waves of up to 1.8 meters in the port city of Iquique and Pisagua in northern Chile. Authorities have ordered evacuation of the coastline.
Un fuerte terremoto sacudió el martes el norte de Chile, desatando un tsunami que llevó a evacuar a varias ciudades y disparó alertas hasta Centroamérica, aunque no se reportaron víctimas o daños graves a la infraestructura de inmediato.

La Armada chilena, que decretó una alarma de tsunami inmediatamente después del sismo, dijo que las olas golpearon las costas y que la marea aumentó en un rango de 1,58 a 1,8 metros según su monitoreo.
De certa forma "já se estava à espera" disto. Notícia do dia 25 de Março:
Quase que acertaram na magnitude até.
Curioso, HAARP queres ver ?
