The most dangerous part of Alaska is the South East area. It’s susceptible to flooding, erosion, and tsunamis. There are also active volcanoes in this area. Scientists have discovered active underwater volcanoes. This area is also susceptible to landslides. This part of AK is vulnerable to many natural hazards, making it the most dangerous part of Alaska.
In October 2015, there was an earthquake in the Wrangell-St. Elias park, causing a landslide of 440 billion pounds. This then triggered a tsunami with waves over 600 feet, devastating the Taan Fjord. In June 2016, a 4,000 ft high mountainside collapsed in Glacier Bay National Park, which caused over 100 million pounds of rock to be deposited onto Lamplugh Glacier. Landslides are particularly devastating, and the fact that this area has a large number of them means that this area is dangerous.
The Queen Charlotte-Fairweather Fault lies in South East AK, stretching for 1200 km. Over the past 120 years, there have been six earthquakes that have been 7 or greater. In 2013, there was a 7.5 magnitude earthquake near the town of Craig, which caused scientists concerned because the fault runs offshore, which could cause major issues in the future.
