The massive bulge, the earthquake, and the snow melting due to magma rising.

∙ 13y agoThere was some warning..... for about two days, there were small earthquakes that couldn't compare to the final earthquake. This final earthquake leveled at 5.1 on the Richter scale.THe volcano fired back with the eruption, thus, these smaller earthquakes were somewhat of a warning. But scientists couldn't crack the code to figure out what was going on. I hope this helped you out in the least bit!

∙ 11y agoDuring the periods of unrest before the eruptions of Mt. St. Helens that have occurred during historical times, people have been warned through different means.
Before the May 18, 1980 eruption there were notifications through daily publications of USGS that the volcano had a potential for an eruption in the near future. As it became apparent to scientists that the eruption was more than likely going to be a large explosive eruption, the police were sent to the houses and forced evacuations of residence within the greatest threat zones near the volcano. Through out all of that however, there were radio broadcasts as well as news coverage of the unrest that the mountain was going through, that led to the eruption.

∙ 13y agoSometimes a volcanic eruption happens with no warning. Other times people may see more smoke than usual and/or feel rumblings in the days leading up to it.
