Final answer:
The eruption of Mount St. Helens can be analyzed on a minute-by-minute basis to understand the sequence of events and their impact. The eruption occurred on May 18, 1980, with an explosive release of ash and gas. The collapsing northern side of the mountain triggered landslides, pyroclastic flows, lahars, and ash fall throughout the day, causing significant destruction.
Step-by-step explanation:
Volcanic Eruption of Mount St. Helens
Minute-by-minute information about volcanic eruptions is especially relevant for monitoring and analyzing volcanic activity. In this case, the eruption of Mount St. Helens can be tracked on a minute-by-minute basis to understand the sequence of events and the impact they had.
On May 18, 1980, at approximately 8:32 a.m., Mount St. Helens erupted explosively. The eruption produced an enormous vertical plume of ash and volcanic gas, and the northern side of the mountain collapsed, triggering a massive landslide.
Following the collapse, pyroclastic flows, lahars, and ash fall continued throughout the day. The eruption caused significant destruction, including the loss of forests, alteration of the landscape, and the loss of human lives.
