Which risk significantly increases downwind when sustained tephra plumes erupt?

💡 Explanation

Long-distance communication systems at lower latitudes face significant risks because tephra particle electrostatic charging and widespread corona discharge causes increased signal attenuation. Therefore interruptions are likely rather than just enrichment since the dust disrupts normal operation.
