Helens remains one of the most extensively monitored eruptive periods for gas emission at any volcano worldwide.

Was Mt St Helens predicted?
Thirteen eruptions of Mount St. Helens between June 1980 and December 1982 were predicted tens of minutes to, more generally, a few hours in advance. The last seven of these eruptions, starting with that of mid-April 1981, were predicted between 3 days and 3 weeks in advance.
What is Mount St. Helens current activity status?
Its been 40 years since Mount St. Helens famously roared to life, sending ash and gas 15 miles high, flattening 135 square miles of forest, and killing 57 people in the countrys deadliest eruption. Today, the volcano is still one of the most dangerous in the United States, and the most active of the Cascade Range.
What monitoring equipment is currently deployed around Mount St. Helens?
The passive-source seismic monitoring will use solar-powered seismometers at 70 sites over about 3,600 square miles centered on Mount St. Helens, and will record local earthquakes and large quakes that occur much farther away, as well as other types of events.
How many died Mount St. Helens?
57 people It was shortly after 8:30 a.m. on May 18, 1980 when Mount St. Helens erupted in Washington state. The eruption would quickly become the deadliest in U.S. history, killing 57 people.
Is it safe to live near Mount St. Helens?
Its nothing to worry about, according to people who live and work beneath Mt. St. Helens. With recent tremors at only 2 on the Richter scale, there is confidence here that the 1980 eruption of the volcano isnt about to be repeated.
How far away from a volcano is safe?
The safe distance from an active volcano is generally 5kms or more but you should check for the latest CDEM information. Beyond this distance the major hazards will be ashfall and volcanic gas. Breathing in small amounts of ash particles infrequently may only cause discomfort rather than pose a health hazard.
Can you outrun a volcano?
Could I outrun the lava and make it to safety? Well, technically, yes. Most lava flows — especially those from shield volcanoes, the less explosive type found in Hawaii — are pretty sluggish. As long as the lava doesnt find its way into a tube- or chute-shaped valley, it will probably move slower than a mile per hour.
