HONOLULU, HI – A Tsunami Warning has been issued for the entire state of Hawaii following a massive 8.7-magnitude earthquake that struck off the east coast of Kamchatka, Russia this afternoon.

According to the Pacific Tsunami Warning Center (PTWC), the quake occurred at 1:25 PM HST, with the warning going into effect at 2:43 PM HST. Officials confirm that a tsunami has been generated and could cause widespread damage along coastlines of all Hawaiian Islands.

📍 Earthquake Details:

• Location: 52.2° N, 160.0° E
• Region: Off the East Coast of Kamchatka, Russia
• Magnitude: 8.7 (Moment Magnitude Scale)
• Origin Time: 1:25 PM HST

_____ 

The first wave could arrive around 7:17 p.m. HST.

Other regions, including California, Oregon, Washington, and Alaska’s Aleutian Islands, remain under tsunami watch or advisory. However, Hawaii is at the highest alert level due to the potential for destructive waves up to 1–3 meters.

1–3 meters is approximately:

- 3.3 to 9.8 feet or about waist-high to just over head-high on an adult

So a tsunami wave in that range can:

• Knock over vehicles
• Flood low-lying areas
• Damage buildings
• Sweep people off their feet

Even “small” tsunami waves carry powerful, fast-moving water that can be deadly.

🌊 Tsunami Impact and Urgency

Authorities are urging immediate evacuation of low-lying coastal areas. The first wave is expected to reach Hawaii by 7:17 PM HST tonight (Tuesday), but officials stress that:

• A tsunami consists of multiple waves — each wave can last 5–15 minutes or more
• The first wave may not be the largest
• Flooding may recur for several hours
• All shores are at risk, regardless of orientation to the epicenter
• Tsunami waves can wrap around islands, creating danger on all sides

Debris carried by the surge, strong and erratic currents, and high surf may amplify destruction, especially during simultaneous high tide conditions.
