No volcanoes were erupting in Kamchatka or the Kurile Islands in January of 1995. In the Pacific northwest a small steam and ash plume erupted from Makushin, a stratovolcano in the Aleutians, on January 30. Makushin has erupted at least ten times since 1768. Aso , Unzen , and Sakura-jima, three volcanoes in Japan that were erupting in January and showed no unusual activity following the earthquake. With a look at the data available to me it appears that the Kobe earthquake did not trigger an increase in volcanism in Siberia, the Pacific Northwest, or Japan.
Some large earthquakes do trigger eruptions.
Details of their model are reported in the article. They also stated that the effect of strain is neither simple nor obvious. Thanks for an interesting question. If you want to discuss this some more you might talk with Professor Tim Kusky at your college, Boston University.
