First Brazilian Workshop on Ionospheric Disturbances due to Natural Hazards
INPE
Recent advances in observational capabilities — including GNSS-based total electron content (TEC) measurements, ionosondes, incoherent scatter radars and dedicated satellite missions — have substantially enhanced our ability to detect and characterise ionospheric perturbations associated with natural hazards. These signals, often referred to as co-seismic or co-eruptive ionospheric disturbances, provide unique insight into the dynamics of lithosphere–atmosphere–ionosphere coupling.
At the same time, extreme weather events such as tropical cyclones, deep convective systems and atmospheric gravity waves induce their own variability in the upper atmosphere, complicating the identification and interpretation of signals tied to solid-Earth processes. The workshop is designed to confront precisely this interpretive frontier.
Bringing together specialists in seismology, ionospheric physics, atmospheric science and space weather, IonoHazards seeks to consolidate the role of South America — and Brazil in particular — as a leading region for research on geophysical coupling and natural hazard monitoring.
