What shape is mount st helens?
Mount St. Helens produced a very large eruption on May 18, 1980. It was a rather unusual eruption. Unlike most eruptions, which go straight up, this one started with a massive landslide followed by a huge sideways-directed explosion, which resulted in the destruction of the volcano's northern face.
Identify at least four indicators of possible criminal or terrorist activity involving chemicals?
multiple victims nauseous and vomiting unexplained vapor clouds unusual security sudden onset unexplained eye irritation unusual odors
Was there an earthquake before the erruption in 79 ad mt vesuvius?
Vesuvius is a volcano that is prone to frequent eruptions, so for the people of Pompey eruptions were not unusual. However the eruption that destroyed the city happened to be significantly larger than what they were used to. At that time there was little actually known about volcanoes and what they are capable of, so the people of Pompey had no reason to believe they were in any danger.
What was unusual about the eruption of Mount st helens?
Most major explosive eruptions eject a large plume of ash straight up. When Mount St. Helens erupted in 1980, the initial explosion was ejected sideways in what is called a lateral blast.
What are the precautionary measures before volcanic eruption?
the precautionary measures to take during a volcanic erruption are to evacuate the citizens of which the lava would effect as quick as possible that is mandatory and without casing even more destruction vent the sulfuric fumes and redirection of the hot lava into open land or river yes this will evaporate the river and kill all wildlife around but is the only way to prevent destruction of homes and landmarks PEACE OUT the proffessionalist
When it is noticed that you are spending an unusual amount on your credit card a . is triggered?
the answer is; warning
Why are diamonds found in certain areas of the world?
Diamonds are formed deep below the earth's crust, and come to us once the volcanic eruption forces the material to the surface. The vertical geology takes the form of a pipe -- a volcanic pipe. (Read link, below.) This phenomenon is unusual and uncommon in the world, thus lowering the numbers of places where diamonds can be found.
What was the unusual thing Jonas noticed when he went to his jod for the first time?
there was no furniture in the room
What causes deaths in Europe in 1783?
Highly unusual conditions were described in the summer of 1783 after Laki, including poisonous volcanic fumes that killed perhaps 25 percent of the population of Iceland, persistent haze and oppressive heat in Europe, and blood-red sunrises over North America, Europe and other locations. The Laki eruption was believed to have caused thousands of deaths because of unusual conditions in Europe that summer, along with the severe cold of the following winter.
Can volcanic eruption be predicted?
There are precipitating factors that can be used to predict a volcanic eruption, including the volcano’s history, how long since its last eruption, and the usual amount of time between eruptions. Other signs include an increased number of earthquakes and a certain level of gas emissions which can be measured via satellite. However, similar to meteorology, there is an inherent level of uncertainty, and the time and severity of an eruption is very difficult to predict.In the case of the 1980 Mt. St. Helens eruption, the preemptive warnings included earthquakes and steam explosions in the months leading up to the blast, prompting the U.S. Forest Service to evacuate people from near the volcano. Although 57 people died, roughly 20,000 were more than likely saved by the evacuations, according to volcanologist William Rose.Alternatively, when the 2019 White Island eruption happened in New Zealand, there were few warning signs. Although a rise in volcanic tremors caused the alert level to be raised from 1 to 2 in the weeks before the eruption, this isn’t an unusual occurrence and usually doesn’t mean a devastating eruption is imminent. "We don't normally see these eruptions coming, no matter how much we would like to," stated Earth scientist Shane Cronin of the blast.

What does unusual sleep patterns mean?

How did Pliny the Younger think his uncle died?
It is said that he collapsed and died through inhaling poisonous gasses from the eruption of Vesuvius. The cause of death is really unknown, he may have been asthmatic and the volcanic fumes contributed to his death
What is one unusual place that a diamonds have been found?
Water that flows over volcanic pipes can tumble diamonds into the sea, and the mouths of some rivers are mined for diamonds.
What is one unusual place diamonds have been found?
Diamonds erupt from deep within the earth's mantle, and some are carried away from the pipe by running water. It makes sense then, but it is unusual, that diamonds are mined in the ocean, at the mouths of rivers that flow over the volcanic pipes.
How do you receive alerts if unusual activity is detected on a web server deployed on a perimeter network?
Deploy an intrusion detection system (NIDS).
