Hello All,

I am just new to this "sport" of seismology and been having lots of fun watching earthquakes 
on my seismometer come in from places near and far. I noticed that there have not been any 
aftershocks from the M7.1 quake in Ecuador on Aug 12. 

All of the other large quakes that I have seen since I started watching quakes in the spring 
have after shocks. Look at the Baja California quake from April, it is still having after shocks 
from that one. The one in the Mariana Island region form yesterday has already had 
numerous after shocks and a M6.3 just a litlle while ago.

Can someone out there tell me what the difference in this quake is that there have not been 
after shocks compared to a "normal" quake with after shocks?

Thanks,
