Unraveling Morocco's 'Blind Earthquake': Satellite Data, Aid Bafflement, and Risk Reduction

Satellite data collected from 430 miles above Earth is providing scientists with crucial information about the recent earthquake in Morocco. The data, obtained through a technique called InSAR, reveals that the earthquake involved both horizontal and upward movement of the land. Analysis suggests that an ancient fault called the Tizi n’Test fault may have been responsible for the quake, despite being inactive in recent history. These "blind earthquakes" are challenging to study as they do not crack through to the surface. The findings contribute to a better understanding of the event and could help assess future risks.
