| In eight groups of rockfalls more than 75,000 years old, broken speleothems are the only record of the prehistoric seismicity. |
| The historic record of seismicity in California is too short to determine confidently how often large earthquakes reoccur. |
| Conversely, when specific seismogenic fault zones have been considered, statistical links between seismicity and eruptive processes are found. |
| High seismicity levels were also observed in 1894 and 1903, due to swarms in the eastern and southern flanks, respectively, apparently not correlated with eruptive activity. |
| Because the bridge is not situated in an area of high seismicity, the earthquake load was not significant and was not a controlling load in the design. |
| This can trigger seismicity in seismically active areas such as volcanoes where there is already a high fluid pressure. |
