Which volcano hazard can be dangerous to passing sir planes due to its fine, abrasive quality?
Volcano ash hazard can be dangerous.
Did scientists predict the mount st Helens eruption?
Yes, it was predicted - both generally in years leading up to 1980 and more specifically in the months before the big blast. In the weeks leading up to the Volcano hazard zones were blocked off around the volcano due to an expected eruption. However the scope and exact timing of the eruption were not forseen - hence 57 people lost their lives.
Do shield volcanoes have high silica content in the lava?
No, shield volcanoes are characterized by lava with a low silica content. Consequently, the principal hazard of the volcano is the lava flow rather than the eruption itself.
What is the main hazard of a quiet volcano?
carbon dioxide
Which volcano hazard is made up of rocky particles about the size of a grain of sand?
Volcanic Ash.
The most dangerous hazard of a composite core volcano is the eruption of lava?
False. The greatest hazard comes from pyroclastic flows.
Which volcano hazard can be dangerous to passing sir planes due to its fine, abrasive quality?
Volcano ash hazard can be dangerous.
What is a volcanic bomb and what causes it?
It is simply the name for a piece of molten rock (larger than 2.5 inches) thrown out of a volcano during an eruption. Despite the name, they generally do not explode (ignore movie special effects) but can be a hazard- large bits of VERY hot rock falling out of the sky.

Is a possible eruption of Mount Rainier that would devastate Seattle Washington a nautral hazard?
Yes, that is a natural hazard.
What is the main hazard of a quiet volcano?
carbon dioxide
What is the main hazard from a quiet volcanic eruption?
it could be gas or just few rocks.
The current that is a serious hazard to swimmers is the?
rip current.
Which environmental hazard is the most serious in Japan?
Earthquakes.
If theres a volcano what can citizen do prepare for this hazard?
If there is a volcano, all anyone can do is leave. When the a Volcano in the Philippines destroyed an American Air Force base, the Planes flew to Eglin in Northwest Florida. If there are warning earthquakes indicating the mountain will explode, a person should pack and leave. With a volcano eruption like happens in Hawaii or Sicily, then a person has time to pack before moving. As we know from experiences on the Windward Islands, it is best to move before the poisonous gas phase comes.
The probabiliy of a single hazard occurring is?
proportional to the cumulative probabiliy of all the causes listed for that hazard
