JUNEAU, Alaska >>  Glitches are being reported in Alaska’s tsunami warning system after Thursday night’s 7.3 earthquake in the Aleutian chain.

State Department of Homeland Security spokesman Jeremy Zidek says tsunami warning messages via TV and radio were sent late, about the same time the warning was being canceled.

The Kenai Peninsula Borough reported its sirens, tied to a weather radio system, only went off when the alert was cancelled, causing some anxiety and bewilderment.

Officials couldn’t immediately say why the glitches occurred, though Zidek says the state does not rely on just one system to alert communities to possible dangers.

He says calls are made and emails are sent to emergency officials. The Kenai Peninsula Borough emergency director says he learned of the warning by email.
