Stay away from anything that could fall in the aftershock, like building facades, power lines, or shelves. The answer is yes. small EQs shake a few seconds but the large 04 Sumatra EQ shook for 10min), larger EQs have typically larger horizontal slip, larger EQs also have larger rupture lengths (the distance along a fault over which the slip occurred), short faults are therefore unlikely to produce large EQs, left-lateral strike slip: rake near 0 deg, right-lateral strike slip: rake near 180 deg, upper (hanging) block slides down on lower (foot) block, upper (hanging) block slides over lower (foot) block, events of all sizes; the largest EQs on Earth are typically along subduction zones The size of an earthquake is known as its magnitude.
