This additional load would work is way down the track of the glacier over a period of years. The earthquake occurred at a depth of 16.9 km (11 miles). More likely, this ground shaking is coming from one of the nearby glaciers. This photo shows the earthquake showing up on sensors across our network.

A 5.2 magnitude earthquake shook Southeast Alaska near the Glacier Bay National Park just before 1 p.m. Wednesday, according to the Alaska Earthquake Center. The Bay was completely glaciated (i.e. That time period corresponds to the depth of the Little Ice Age (LIA), which wamists would have you believe was an localized European phenomenon. to a bit below the bottom of the map above) in 1750-1780. The earthquake originated along the Fairweather Fault, which runs along the shore and beneath a narrow fjord known as Lituya Bay. Lituya Bay is an ice-scoured tidal inlet with a max­i­mum depth of 722 feet (220 m). The earthquake hit on Wednesday at 11:58 GMT southwest of Haines, which has a population of over 2,500 people.
