Resident shared photos of the damage inside their home showing broken glass and furniture. Seismologists say tonights quake was the main event. Yesterdays 6. 4 quake was a for shock. The fault is growing. Ruptur first earthquake. We ruptured a bit more on the quake this morning. We are rupturing more now. It is moving to the northwest away from the metro area as far as we can tell. By definition because the 7. 1 is the largest we give it the main shock. Yesterday or an hour ago we were calling the 6. 4 the main shock. It is now had an aftershock it is bigger than itself. We change the name. The 6. 4 is a for shock. The large aftershock has become the main shock. As far as we can tell those names are semantic. There are tools for trying to describe what is going on. But when you have a sequence going on every earthquake makes another earthquake more likely. That is what we are seeing right here. They have been several aftershocks one of which was a fivepoint seven magnitude. Seismologis
