文摘
- •
Pulse periods of interplate records are longer than pulse periods of intraplate records with similar magnitude.
- •
Differences in the pulse period of interplate and intraplate earthquakes imply different local stress drops.
- •
The pulse period is longer at soil sites than at rock sites for smaller earthquakes.
- •
The pulse period values at rock and soil sites converge for larger earthquakes.
- •
The effect of soil conditions on pulse period is not statistically significant at the 10% level.
