Abstract
THE French test series in the summer of 1970 consisted of eight announced atmospheric explosions in the Tuamoto archipelago in the South Pacific, and ended with a small explosion on August 6 (ref. 1). In this series there were two large explosions on May 30 and July 3. The explosion on May 30 (Dragon) was fired at 1800 GMT above the Fangataufa lagoon about 1,400 km south-east of Tahiti2,3. The explosion on July 3 (Licorne) was fired at 1830 GMT at 1,800 feet above sea level above the Mururoa Atoll, about 60 km north-west of Fangataufa, and had a yield of about one megaton4. This article reports the long period seismologic and microbarologic signals from these two explosions, recorded at the Hagfors Observatory in Sweden. No short period seismologic signals were obtained.
