The epicenter was near Itacarambi, in the São Francisco Craton area.
The "mb" in 4.9 mb stands for . This scale measures the P-waves (primary waves) that travel through the interior of the Earth. It is specifically useful for deep-focus earthquakes or those occurring at distances where other scales might be less accurate. 4. Why This Matters Today
Ensuring infrastructure can withstand rare but possible tremors. (4.9 MB)
At a magnitude of , the quake was powerful enough to cause significant local concern.
Researchers continue to study the Caraíbas–Itacarambi earthquake to improve hazard maps for Brazil. Understanding these "sleeping" faults helps in: The epicenter was near Itacarambi, in the São
It was one of the first times an earthquake in this specific region was documented with such precision, helping geologists map hidden fault lines beneath the Brazilian soil. 3. Understanding the "mb" Scale
Identifying where stress might be building within the South American Plate. It is specifically useful for deep-focus earthquakes or
This event is particularly notable in seismology because it was an , meaning it happened in the middle of a tectonic plate—an area usually considered geologically stable.
