Disclosed is a disaster warning device with a guided surface wave receive structure, an impedance matching network, a power circuit, a data processing circuit, and a warning output. The power circuit and the data processing circuit may be coupled to the guided surface wave receive structure. The power circuit may supply electrical energy to power to the data processing circuit and warning output. The power circuit may receive power from a guided surface wave. The data processing circuitry may receive data communications from a guided surface wave.
