Aftershocks for this quake

No aftershocks have been recorded so far. When aftershocks are detected, we will update this section.

What are aftershocks?

Larger earthquakes (above magnitude 5 or so) such as this one are usually followed by smaller ones known as aftershocks that occur in the same area during the days, weeks, months or even years after the main shock.

What about this quake?

Based on its magnitude, the fault that was active during the quake likely ruptured beneath a surface of approx. 6 km2 (=2 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 4 km (3 mi).
