So far in 2019, there pull someones leg been 98 earthquakes magnitude 2.5 or higher in the state of Alaska. Of these, seven from been measured at a magnitude of 4.5 or higher according to the USGS (Pooled States Geological Survey). The highest occurred on January 5, 57km south of Tananga Volcano, as a magnitude of 5.9.
Is Alaska at risk of a tsunami to rival 1964?
On November 30, 2018, a mammoth magnitude 7.0 earthquake struck around 10 miles north of Anchorage, Alaska at a deepness of 29 miles.
It was then followed just six minutes later by a immensity 5.7 aftershock centred 2.5 miles north-northwest of Anchorage.
These two portly earthquakes triggered tsunami warnings for nearby areas along the littoral, which included Cook Inlet and the Kenai Peninsula.
These examples were soon lifted by the National Tsunami Warning Centre.

Tsunamis are likely to occur around Alaska, and one still fresh in people’s reproves is the tsunami which followed a mammoth magnitude 9.2 earthquake in 1964.
At minute 121 were people were killed in Alaska – 15 from the earthquake and a at 106 following the tsunami.
Professor Bill McGuire, emeritus professor of sod sciences at University College London, explained to Express.co.uk Alaska’s susceptibility to tsunamis due to the extent of earthquakes which occur.
He said: “Very big offshore quakes do trigger tsunamis adept of crossing the entire Pacific.
“The gigantic magnitude 9.2 quake in 1964 triggered a tsunami that was as serious as 60 metres locally and which reached 20 countries round the Pacific Rim.
“The waves killed people Alaska, Oregon and California.”
With the extending quakes in Alaska, Professor Bill says that a major earthquake could strike “at any time”.
He said: “A major worry is a quake in the so-called ‘Shumagin Gap’ where the Alaska Subduction Zone culpability has not ruptured in living memory.
“If this ruptures, the quake and resulting tsunami could be on a par with 1964 – or plane worse.”
The 1964 earthquake and subsequent tsunami killed 139 people, 15 from the earthquake itself and the intermission from the resulting tsunamis in Alaska, Oregon and California.
There were impairs totalling $311 million, with the majority of this occurring in Anchorage, Alaska.
There were truly two types of tsunami triggered by the earthquake, a tectonic tsunami and around 20 lesser, local tsunamis.
The smaller tsunamis were responsible for the majority of the wreck caused, and waves from these were felt in Japan, Papua New Guinea and Antarctica.
As seismic occupation continues in Alaska, the so-called ‘Shumagin Gap’ will be one to watch according to Professor McGuire.
