  1. Earthquake

    The huge M8.8 earthquake at Kamchatka Peninsula last night not only shook the earth. It also generated gravity waves in the atmosphere which echoed around the world, causing the ionosphere to oscillate too.

    Amateur DXers around the world have detected variations in the signal strength and Doppler shifts of HF (3-30 MHz) and VLF (3-30 kHz) radio stations shortly after the earthquake occurred. Some signal plots are attached from 7L4IOU and F5VLB (via the "Dopplergram" Google group).
