In summary, a mainshock is the largest earthquake in a series and is followed by smaller aftershocks which can continue for a long time. The magnitudes 6.8 and 6.0 represent strong and moderate earthquakes, respectively. The mainshock and aftershock are usually within the same region. There is always a possibility of more aftershocks, but their frequency and intensity decrease over time. If you are in the affected area, it is important to follow instructions from local authorities and be prepared for potential aftershocks.

FAQ: M 6.8 mainshock and 6.0 aftershock coming in NOW on seismo system

What is a mainshock and aftershock?

A mainshock is the largest earthquake in a series of earthquakes, usually followed by smaller earthquakes known as aftershocks. Aftershocks can continue for weeks, months, or even years after the mainshock.

What do the magnitudes 6.8 and 6.0 mean?

The magnitude of an earthquake is a measure of the energy released by the earthquake. A magnitude 6.8 earthquake is considered a strong earthquake, while a magnitude 6.0 earthquake is considered a moderate earthquake.

How close are the mainshock and aftershock to each other?

The distance between the mainshock and aftershock can vary, but they are usually within the same general region or area.

Is there a possibility of more aftershocks?

Yes, there is always a possibility of more aftershocks following a mainshock. The frequency and intensity of aftershocks decreases over time, but they can continue for weeks, months, or even years after the mainshock.

What should people do if they are in the affected area?

If you are in the affected area, it is important to follow any instructions or evacuation orders given by local authorities. It is also important to stay informed and be prepared for potential aftershocks by having an emergency plan and supplies ready.
