A proposed earthquake early warning system could have provided several Alaska communities an alert of 10 seconds or more ahead of strong shaking from the magnitude 7.3 quake that occurred south of Sand Point near the tip of the Alaska Peninsula in mid-July.
A proposed earthquake early warning system could have provided several Alaska communities an alert of 10 seconds or more ahead of strong shaking from the magnitude 7.3 quake that occurred south of Sand Point near the tip of the Alaska Peninsula in mid-July.
That analysis is provided by Alex Fozkos of the Alaska Earthquake Center’s systems team at the University of Alaska Fairbanks Geophysical Institute.
“Individuals in Sand Point could have expected approximately 10 seconds of warning time before shaking increased to its strongest,” Fozkos said. “In King Cove, individuals could have expected a warning of approximately 20 seconds.”
