Old Faithful, the iconic geyser in Yellowstone National Park, continues to captivate visitors with its regular eruptions. Recent activity shows that Old Faithful maintains its predictable pattern, erupting approximately 20 times daily. The intervals between eruptions range from 35 to 120 minutes, with an average of 90 minutes. Despite minor changes due to seismic events, Old Faithful remains one of the most reliable geysers, with predictions accurate within 10 minutes about 90% of the time.
What Are the Current Eruption Patterns of Old Faithful?
Old Faithful’s recent activity follows a consistent pattern:
- Eruption intervals: 35 to 120 minutes
- Average interval: 90 minutes
- Eruption duration: 1.5 to 5 minutes
- Eruption height: 106 to 180+ feet
- Daily frequency: Approximately 20 eruptions
The prediction of the next eruption depends on the duration of the previous one. For instance:
| Eruption Duration | Predicted Interval |
