📐🧱 Seismologists at #Egypt’s National #Research Institute of #Astronomy and #Geophysics measured vibrations inside the Great #Pyramid of #Giza.

They found its frequency differs significantly from the surrounding #soil, preventing seismic amplification. The stability resulted from centuries of Egyptian architects refining slopes and structural layouts through trial and error.

Congratulations, Anna Kelbert, for thoroughly mapping subsurface electrical resistivity.

We are vulnerable to #geomagneticstorms. Understanding the risk is important, but we also need timely predictions and effective responses.

@SciXCommunity, she is establishing the basis for such capabilities.
