What is a seismic gap?

A seismic gap is a region along a tectonic plate boundary where there has not been a significant earthquake in a long time, even though there is strain building up in the Earth's crust. These areas are considered to be at higher risk for a major earthquake in the future, as the built-up stress is likely to be released in a sudden rupture.

Seismic gaps are identified through the study of historical earthquake records, GPS measurements of crustal deformation, and observations of the movement of tectonic plates. By monitoring these gaps, scientists can better understand the potential for future earthquakes in a given region and help to improve earthquake forecasting and preparedness efforts.

It is important for residents and authorities in areas with seismic gaps to be aware of the potential risk of a future earthquake and to have emergency plans in place to mitigate the impact of such an event. Additionally, ongoing monitoring of seismic activity in these regions can help to provide early warning of impending earthquakes and allow for timely evacuation and preparedness measures to be implemented.
