The 1980 Mount Saint Helens eruption was the most destructive volcanic eruption in U.S. history. Which statement best describes one major change in strategy that scientists made to reduce the effects of a future eruption from Mount Saint Helens?(1 point)
Scientists dramatically increased the number of seismographs monitoring the volcano’s activity to warn people to evacuate the area.
Scientists installed a metal barrier around the base of the volcano to protect the surrounding forests from a flow of volcanic debris.
Scientists created an invention to collect ash as it pours into the air to prevent pollution.
Scientists established additional campsites closer to the volcano to allow more people to observe the volcano’s activity.

Seismic station installation in Mount St. Helens's crater 1981 lava dome. USGS, in conjunction with the University of Washington, maintain seismic stations at Mount St. Helens. An increase in seismicity (earthquakes) is often the first precursor to an approaching eruption.
:) is 100% correct thank you
thx :)
thank you ":)"
The correct answer is: Scientists dramatically increased the number of seismographs monitoring the volcano's activity to warn people to evacuate the area.
To arrive at this answer, it is necessary to understand the context of the question. The question asks about one major change in strategy that scientists made to reduce the effects of a future eruption from Mount Saint Helens.
To determine the answer, we need to assess the four statements provided as options and choose the one that best describes a change in strategy made by scientists.
Statement 1 suggests that scientists increased the number of seismographs to monitor the volcano's activity and provide early warning for evacuation. This change in strategy is aimed at reducing the effects of a future eruption by giving people more time to evacuate and minimize casualties.
Statement 2 suggests that scientists installed a metal barrier to protect the surrounding forests from volcanic debris. While this could be a valid strategy, it does not specifically address reducing the effects of a future eruption.
Statement 3 suggests that scientists created an invention to collect ash and prevent pollution. While important for environmental concerns, this strategy does not explicitly address reducing the effects of a future eruption.
Statement 4 suggests that scientists established additional campsites to allow more people to observe the volcano's activity. This strategy may promote public awareness and education, but it does not directly tackle reducing the effects of a future eruption.
Based on this analysis, the most appropriate answer is Statement 1: Scientists dramatically increased the number of seismographs monitoring the volcano's activity to warn people to evacuate the area.
