Term
| lake sediment records as a paleoseismology tool |
|
Definition
| lake sediment records can be used to look at the timing of past landslides. when landslides occur, they dump non-organic material onto lake bed. this is distinct from the organic material that is deposited the rest of the time. Landslides are related to earthquakes, date the landslides and you can date the earthquakes |
