A little more than 650 aftershocks have been recorded off Valparaiso since a M6.9 earthquake hit the region 10 days ago.

This intensification in seismic activity frightens the Chilean population, which has started to prepare in fear of a Big One.

More than 650 earthquakes hit alparaiso, Chile since the M6.9 earthquake on April 25 2017. via CSN and El Informador Chile
A little more than a week after the strong M6.9 earthquake that hit 72 kilometers west of Valparaiso in Chile, the National Seismological Center (CSN) reported that more than 650 aftershocks have been meaured in the region. About 130 tremors hit the region prior the major event.
Sergio Barrientos, director of the CSN and doctor of seismology at the University of California, says there is no way to know how long the replicas will last or how many there will be in total. Everything will depend on the moment when the deformation and the friction of the plates will stop.

This long swarm of quakes is not eluding a mega earthquake in the area

People often forget that earthquakes are measured on a logarithmic scale. For example, the energy difference between a M6.0 and a M7.0 is 32 times more energy, and between a M6.0 and a M8.0 is 900 times more.
