31 Οκτ 2023 · By about 30,000 years ago, Mount Mazama began to generate increasingly explosive eruptions and thick flows of silica-rich rhyodacite lava. The change to more explosive and silica-rich eruptions was an outward sign that a large volume of silicic magma had begun to accumulate deep beneath the volcano.
Thousands of years ago Mount Mazama, a 3,700-meter volcanic mountain covered the Crater Lake site. Beneath the mountain was a large chamber of magma, a collection of gas and molten rock. In a tremendously powerful eruption more than 6,000 years ago, cracks opened beneath the volcano and drained away several cubic kilometers of molten material.
23 Οκτ 2023 · The massive volcano erupted violently 7,700 years ago, accompanied by collapse of the entire upper half of the edifice. Prior to its climactic eruption Mount Mazama had a summit elevation of about 3,700 m (12,000 ft). The present high point is Mount Scott at 2,721 m (8929 ft), 3 km (about 2 mi) east of the caldera rim.
30 Οκτ 2023 · The climactic eruption of Mount Mazama devastated the terrain for tens of kilometers from the volcano, sent pyroclastic flows as far as 70 km (43 mi) down every valley heading on the volcano, and produced ash fall throughout much of the Pacific Northwest and parts of southern Canada.
