Chile – M 4.8 – Moderate quake 55 km from Conception

Earthquake Report comment :
A for Chilean standards very moderate earthquake in the coastal waters near Conception.
The shaking in the coastal towns of Talca and Conception was felt as “weak”

On Februari 27, 2010  a powerful Magnitude 8.8 earthquake struck in the same area killing more than 521 people (most of them by a coastal Tsunami).  Thanks to the strict building codes enforced by the government since the early seventies, a greater tragedy has been avoided.
Seismologists estimate that the earthquake was so powerful that it may have shortened the length of the day by 1.26 microseconds and moved the Earth’s figure axis by 8 cm or 2.7 milliarcseconds.
