We can divide the effects of an earthquake into those known as the primary effects and those known as the secondary effects. Primary effects of an earthquake are those resulting directly from the earthquake itself. These include; buildings collapsing; roads cracking; bridges giving way; shattering of glass and injuries / deaths resulting from these. Secondary effects are those that result from the primary effects. For example ground shaking may result in the cracking of gas and water pipes (primary effects) this can result in severe fires due to explosion from escaping gas and difficulties in putting out fires due to lack of water from burst mains (secondary effects). Other secondary effects include, homelessness, business going bankrupt and closing etc.

It is said to have erupted many times, but the most famous eruption was on May 18, 1980, which took out most of the forest around it.
Effects on the landscape: 400 meters of the mountain was blown off and a 500 meter horse shoe crater was made. Approximately 7000 animals died within 25km north side of the volcano. Every tree within 30km was flattenedThe melted ice created mudflows down the mountains flowing into streams killing about 12 million salmon. The eruption destroyed 250 homes, 47 bridges, 15 miles of railways and 185 miles of highwayEffects on people:57 people died whilst most were evacuatedAsh clogged up car engines and farm machinery. The cost of ash damage totalled £100 million.15cm of ash fell cancelling flights and causing traffic chaos Telephone lines and electricity supplies were cut offTourists no long visited the area causing a reduction in the local economy.
volcano eruptions are triggered by seismic activity, meaning earthquakes and such. Mt St Helens is along the ring of fire, which is full of seismic activity.
yes
a lot of ash and fires
The 1980 eruption of Mount St. Helens in Washington state resulted in the loss of 57 lives, significant destruction of the landscape, and caused widespread ash fall across several states. It also led to the formation of a large crater at the summit of the volcano and resulted in the outpouring of lava flows.
It killed animals and stuff. And people. Look at wikipedia.
