5.7 How do we know how to interpret unseen turbidity currents?
A turbidity current documented in 1929 off Grand Banks in SE Canada. Several telegraph cables immediately broke when an earthquake occurred. An hour later, another cable much farther out to sea broke as well. Over the next 17 hours, progressively farther cables continued to break.
The area has since been sampled and we now know that this event moved 175 km3 of sediment—enough to cover the state of Indiana 1 meter deep.
