Seismicity sometimes occurs in zones, such as has been observed under Mercer Island, or from downtown Seattle towards Kirkland [214] but whether particular zones reflect undiscovered faults, or might be the source of damaging earthquakes, is generally unknown. Ongoing mapping is revealing more faults.
Mackenzie, Muschalik & Broesche (2021) provided comments on the 2018 report in three separately authored sections. [4] Broesche believes that Yellowstone should be ranked higher due to the size of the volcano and the popularity of Yellowstone National Park, and Muschalik considers Mount Rainier to be just as dangerous as Kilauea due to its proximity to large population centers in Washington.
‘Most dangerous volcano in the Cascades’ The lowlands around the Puyallup River, down to Commencement Bay, could be affected by a lahar, said Steve Malone, a retired seismologist with the ...
Twelve volcanoes in the arc are over 10,000 feet (3,000 m) in elevation, and the two highest, Mount Rainier and Mount Shasta, exceed 14,000 feet (4,300 m). By volume, the two largest Cascade volcanoes are the broad shields of Medicine Lake Volcano and Newberry Volcano, which are about 145 and 108 cubic miles (600 and 450 km 3) respectively.
The eruption of Mount Agung on the island of Bali has sparked worldwide interest on possible other eruptions from the globe's volcanoes. Scientists weigh in on 6 volcanoes that are heating up in ...
The Seattle Fault is the structural boundary where 50–60 million years old (early Tertiary) basalt of the Crescent Formation on the south has been uplifted – the Seattle Uplift – and is tipping into the Seattle Basin, where the Tertiary bedrock is buried under at least 7 km (4.3 miles) of relatively softer, lighter sedimentary strata of ...
Mount Ruang spewed lava and and ash on April 17, seen from Sitaro, North Sulawesi. It also triggered lightning in the ash cloud -- a common phenomenon in powerful volcano eruptions.
