7.5 magnitude earthquake in Alaska triggered a small tsunami


A 7.5 magnitude earthquake occurring around Sand Point, Alaska triggered a small tsunami, with two waves reaching 130 centimeters (4 feet, 3 inches) high.

A #tsunami with a height of 1.5 ft/0.45 m has been observed at King Cove in addition to the 2 ft/0.6 m wave seen at Sand Point, AK. The tsunami warning remains in effect for South Alaska and the Alaska Peninsula.

The National Tsunami Warning Center said Monday afternoon that the earthquake has triggered the two seismic waves, but as per observers onshore, the waves did not reach 1.5 feet (45.7 centimeters) and 2 feet (61 cm) over high tide, CNN reported.

The #tsunami Advisory for South Alaska and the Alaska Peninsula is canceled. No tsunami alerts are in effect anywhere.

On Monday, the US department reportedly downgraded the tsunami advisory it originally prompted earlier that day, saying chances of damages are ‘pretty remote.’

A sand point clinic employee speaking to CNN said they felt the quake and it was a big one. Despite the threat warning has been retracted, people of the region have moved to higher grounds.

Despite the earthquake was felt across the peninsula, the city is thankfully intact, city administrator Gary Hennigh told the Anchorage Daily News.

Local authorities have urged people to stay on the higher grounds unless stated safe to return.

The 7 magnitudes plus quake was followed by a lesser 5.0 magnitude or higher aftershocks. This seismic event comes three months after a 7.8 magnitude earthquake struck a nearby region, AFP noted.

Alaska is, by nature, prone to earthquakes, having situated in the seismically active Pacific Ring of Fire. In 1964, the US state was hit by a 9.2-magnitude earthquake — the largest ever recorded in North America, and one of the world’s largest.

Earthquakes above 7 magnitudes are usually prompted as being destructive. On June 23rd, a 7.4 magnitude earthquake jolted central Mexico killing at least 7 people, We The World reported.

Similar tsunami warnings was prompted, but the risks receded later.
