The U.S. Pacific Tsunami Warning Center said Monday evening that a magnitude 7.8 earthquake had occurred off the coast of Russia's Kamchatka Peninsula.
"Based on preliminary earthquake parameters... hazardous tsunami waves are possible for coasts located within 300 km (186 miles) of the earthquake epicenter," the center wrote in an official message.
Tsunami waves, however, were unlikely to reach Kamchatka's eastern coast, some 500 km (310 miles) away.
The quake was followed by several aftershocks, including a couple above magnitude 5.0.
The earthquake was originally reported as a 7.4 magnitude, but it was subsequently upgraded to 7.8.
The Kamchatka unit of the Russian emergencies ministry said it expected the tsunami wave to be no bigger than 0.5 meters. It told Interfax that Nikolskoe residents reported feeling tremors as did some people living in Petropavlovsk-Kamchatsky, the provincial capital. The quake comes shortly after a powerful spewing of ash from the Klyuchevskoy volcano in Kamchatka. The ash plume rose to a height of 6 kilometers above sea level, prompting an advisory for planes flying in the region, local media reported.

While I understand the rule I really dislike needing to use the article title from a source..
The title of this thread reads like the Tsunami wave is a guaranteed thing yet reading the article says" waves are possible"

What?
How did they know? Is that what you're saying? Russia announced this 12 hours before it occurred? I'm confused.
