Four additional aftershocks occurred on Sunday, December 12.
A 2.4 aftershock occurred at 7:51 am.
A 2.3 struck at 10:13 am.
The largest, a 2.8 hit at 5:19 pm.
Finally, a 2.2 occurred at 10:57.
By definition, these seismic tremors after aftershocks because:
- They occur after an earthquake of 4.0 or higher on the Richter Scale
- They all occur within the vicinity of the original earthquake
- They register lower on the Richter Scale than the earthquake which proceeded them
Sometimes, aftershocks can last days or weeks after the initial earthquake. The larger the earthquake, the longer the aftershocks will last.
