文摘
- •
We provide insight into earthquake-triggered liquefaction in southern Siberia.
- •
We describe SSDS associated with some recent seismic events.
- •
We suggest criteria to separate the seismogenic dikes from non-seismogenic SSDS.
- •
These criteria make dikes a reliable indicator of paleoseismicity.
- •
Fractures and sinkholes may indirectly also point at a seismic origin of dike.
