Default 4.8 earthquake felt in the sa area

It's been upgraded to a 4.8 per the USGS.GOV site who monitors earthquakes. This reading would be a record for our area in terms of the strongest felt thus far. Looking at the various comments out there on media outlets it appears that a huge area felt it. Reports of chairs moving and buildings swaying we sporadic in the Medical Center area and downtown SA area. I would imagine that there will be some damage to structures closer to the epicenter. This quake was I believe the same size of the DC area quake that hit recently!

slept right through it (or didn't feel it on the far westside). dogs didn't feel it either. but having lived in an earthquake prone area, i think i also learned to sleep through benign waves

i'm enjoying these news reports, hehehe.

I was not aware that we were in a seismically active region, although technically no part of the Earth is really ever inactive. I'm sure there is a geology aficionado somewhere on this board so would you mind explaining what is going on.

What fault caused this event and what type is it?

What is the seismic history of this region? Was there ever a big one?

I did not feel a thing even though I am very familiar with lots of small ones having lived in the San Francisco Bay area for almost a decade. Does sitting on a big chunk of limestone out here north of 1604 buffer you from seismic wave effects? I'm thinking this would be the opposite effect of the great damage caused by the 1985 Mexico City earthquake due to the ancient soft lake bed the city was built on.

Anyway, I could research all these things, but I'm hoping there is a knowledgeable person out there who wouldn't mind sharing with me/us.

Inquiring minds want to know.

lol a 4.8 isnt going to cause much damage. maybe a few knocked over chairs, MAYBE some damage to older foundations, but that would be it. we have building codes for a reason

Historically, an earthquake this large is rare for the region. Some are attributing this event to deep injection wells from the Eagle ford.

We have the Balcones Escarpment:
Balcones Fault - Wikipedia, the free encyclopedia

I also believe there is an outcrop of the Edwards around Falls City. Not sure if it is active.
