Son of Godzilla
The Radioactive Sonde was a major part of the Weather Control Capsule. It would spay a gas that would change the climate. However, something went wrong, and the Sonde exploded, releasing radiation onto Sogell Island. The radiation caused a heat wave and terrible storms. The radiation also caused the native giant mantis to mutate into Kamacuras. The Sonde was deployed again, this time successfully, and caused the island to cool drastically.
