Abstract
Several experiments in ice-covered regions are instrumenting balloons or mountain tops with antennas to look for a radio signal from ultra-high-energy neutrinos skimming the Earth’s surface. In addition to the well known "mystery events" observed while ANITA flew over Antarctica, the mountain-top experiment TAROGE-M has recorded an anomalous cluster of radio signals from a nearby glacier from where no human-made backgrounds had been expected at first. There are many observations of radio emission associated with the fracture of ice and other solid materials. The available reports span across different disciplines and consequently focus on frequency ranges and sampling rates below what is relevant for radio neutrino detection. For this contribution we made an inventory of the available literature and attempted to measure radio emission from cracking ice in the laboratory. We intend to alert the radio neutrino community on the possibility that fracture of glacial ice may constitute a background for radio-neutrino experiments.
