The Kurily (in Russian, "smoking") Islands region is of high seismicity. In the General Catalog, one can see many large events, beginning in 1737.
Magnitude
| Period | M=>8 | 7-7.9 | 6-6.9 | 5-5.9 | 4-4.9 | Total |
|---|---|---|---|---|---|---|
| 1737-1861 | 2 | 33 | 174 | 68 | 13 | 271 |
| 1962-1990 | - | 10 | 127 | 782 | 629 | 1666 |
Earthquakes as deep as 100-500 km, and occasionally even more then 600 km are found in the Regional Catalog. For example, in the General Catalog there are:
Depth
| Period | >600 | 500-599 | 300-499 | 100-299 | 50-99 |

| 1962-1990 | 8 | 25 | 70 | 330 | 387 |
The local catalog data for this Region are still unavailable in digital format and are not included in the Composite Regional Catalog. However, the energy class, KFS (after Fedotov) or Kc (after Soloviev & Solovieva), were the source for the magnitude (M) calculation that was included in the General Catalog.
