What makes a tsunami and what to do if one comes
Briefly

A significant 8.8-magnitude earthquake struck off the coast of Russia, prompting tsunami alerts in several Pacific regions, including Hawaii and Japan. Residents in Hawaii, such as Siri Zama, reacted with concern and fled inland as dark clouds and rain intensified. Areas close to the earthquake experienced flooding, while no substantial damage or fatalities have been reported. Tsunami generation requires a strong earthquake, typically of at least magnitude 6.5 to 7, especially if it occurs underwater or near coastlines. The Ring of Fire is a notable zone for such seismic activity.
"Tsunami alerts lit up Siri Zama's phone on Tuesday. The 28-year-old high school teacher in Kapolei, Hawaii, fled inland, feeling scared and worried as he watched the dark clouds."
"An 8.8-magnitude earthquake struck Russia's Far East early Wednesday, sending tsunami waves toward Japan, Hawaii and other areas across the Pacific, while flooding occurred near the quake's epicenter."
