Common Questions about Earthquakes in San Juan
How often are earthquakes recorded in the San Juan area?
In the past 7 days, the number of earthquakes of magnitude 1.5 or above recorded in San Juan was 34. These figures describe the available records, not a prediction of future earthquakes.
What makes an earthquake “significant”?
It is not just about magnitude: reported shaking and estimated impacts also matter. The significant-events filter highlights events that meet the site’s criteria; it is not a warning or a complete list of felt earthquakes.
How strong was the largest recent earthquake in the San Juan area?
The largest earthquake recorded in San Juan in the past 7 days had a magnitude of 3.4. These figures describe the available records, not a prediction of future earthquakes.
How far back does the earthquake data go?
The historical search starts in 1900, but available records vary by region and source. Older and smaller earthquakes may be missing. A long search can reach the list’s display limit, so narrow the date range to explore it in more detail.
