Homework Statement
A recent earthquake occurred in SE Mexico and was recorded in Ohio.
1. Which Component (BHZ: Up-Down, BHE: East-West, BHN: Noth-South) of hte seismogram should we look at for the best recording of the P wave?
2. Which Component (BHZ: Up-Down, BHE: East-West, BHN: Noth-South) of hte seismogram should we look at for the best recording of the SH wave?
Homework Equations
I know that P waves propagate in every direction and SH waves are the s waves that are horizontal.
The Attempt at a Solution
From the given seismograms I choose for P waves BHE and for SH waves I choose BHZ.
I understand this problem is dictated by location from earthquake in SE Mexico to Ohio, but I can't understand how to look at it. If that were the case, wouldn't SH wave be best East-to-west (BHE) instead of BHZ?
