THE last quarter of 1947 opened with an earthquake on October 3 which was felt most strongly at Santarem, caused some alarm in the working-class districts of Lisbon, and damaged many buildings in Lisbon, Cascaes and Estoril. There were about ten other strong earthquakes in October in various parts of the world, including the one felt strongly at Coroni in southern Greece on October 6, and another felt strongly and causing some property damage 40 miles south-west of Fairbanks in Alaska on October 16. The latter had an aftershock on October 20. During this month, thirty-eight small earthquakes and "arth tremors were felt in New Zealand, the greatest being on October 13 from an epicentre at lat. 44.2° S., long. 169.0° E., felt over most of the South Island. November opened with an intense earthquake on November 1, 150 miles north-east of Lima in Peru. This caused considerable property damage and also was responsible for the deaths of at‘least fifty-three people. Strong aftershocks of the earthquake occurred on November 7 and 25. Of the fourteen other strong earthquakes during the month, that on November 23 in south-west Montana was felt in Montana and Idaho. In December, some thirteen strong shocks occurred, the European ones being felt on December 13 in the Pyrenees, on December 20 in the Tirol and on December 25 at Lago d‘Iseo in Italy.
