Vancover, B.C. - A remote volcano on Russia's central Kuril Islands is affecting air travel between Vancouver and Asia.

Air Canada has issued an advisory warning that its flights between Vancouver and Tokyo, Seoul, Beijing, Shanghai and Hong Kong could be disrupted by volcanic activity at Sarychev Peak.

The airline says weather conditions could be affecting the volcano in the North Pacific Ocean and delays or cancellations are expected in the coming days.

Air Canada says impact on its Toronto-Asia flights is expected to be minimal.

Sarychev Peak belched ash plumes on June 12, spreading clouds of volcanic material over several hundred kilometres to the northwest and southeast.

Eruptions have been recorded at Sarychev Peak for more than 200 years, ranging from relatively calm lava flows to explosive blasts.
