India Meteorological Department (IMD) Director (Amaravati) S. Stella told The Hindu that this was a minor, low-intensity earthquake. Typically, cracks in roads and buildings begin to appear in quakes measuring 5.0 or higher, though the impact depends on various factors. In the case of G. Madugula, the tremor was likely not that strong, which is why it was felt only in nearby areas such as Visakhapatnam, Vizianagaram, and Srikakulam.
She added that road damage generally occurs in earthquakes measuring 5.3 or higher, though this is not certain and depends on factors such as proximity to the epicentre and the quake’s specific intensity. Earthquakes with a magnitude between 5.0 and 5.4 usually cause minor damage, while those around 6.0 can be destructive in localized areas. Quakes reaching 7.0 or above tend to cause severe damage across a wider region.
