What else can I help you with?
Can a volcanic eruption be preceded by a small eruption?
Yes. This is relatively common for larger eruptions.
Does a pyroclastic flow occur during during small earthquakes?
No. Pyroclastic flows are a result of volcanic eruptions.
Is there any kind of early warning of volcanic eruption?
Yes, there is early warning before most volcanic eruptions. The primary sign is small earthquakes or land tremors and shakes near the volcano.
Eruptions that are characterized by small explosions and thick lava flows are what?
Volcanic eruptions.
Can a volcano cause a storm?
Yes. A volcanic eruption is often preceded by earthquakes and steam coming from the volcano. Sensitive instruments can detect small changes in elevation as molten rock moves underground. Large volcanic eruptions are often preceded by a series of smaller ones.
What three methods do scientist's use to predict volcanic eruptions?
Four clues that scientists use to predict eruptions are... -studying dormant volcanoes -monitoring small earthquakes that occur before the eruption -studying the ratio of gases collected -studying active volcanoes
What causes small earthquakes before a volcanic eruption?
The earthquakes are caused by the movement of magma underground and the breaking of rocks by that magma.
How do you predict a volcanic eruption using GPS?
You don't. Prediction of volcanic eruptions, earthquakes, and other geological phenomena cannot be made. Guesses might be made from measurement of land movement with GPS, small tremors with seismographs, and heat flow with IR scanners, but they aren't accurate enough to call them predictions.
When small earthquakes are a volcano they are what?
When small earthquakes result in a volcano, they are caused by a slip on a fault near an existing volcano. In 1981, the largest felt volcanic earthquake occurred in the Cascades.
How are volcanoes and earthquakes the same?
Earthquakes and volcanoes can both make the ground shake. Both of these natural disasters also cause an extreme amount of damage. A volcano is different from an earthquake in the fact that they produce lava.
What type of material is produced by explosive eruptions?
Explosive eruptions typically produce pyroclastic material, which includes volcanic ash, lapilli (small rocks), and volcanic bombs (larger, rounded projectiles). These materials are ejected with great force during explosive eruptions, causing widespread damage and forming deposits around the volcanic vent.
How many volcanos erupted in last 30 years?
There have been approximately 1500-1600 volcanic eruptions in the last 30 years, with some years seeing more activity than others. Volcanic eruptions can vary in scale and impact, from small, short-lived eruptions to large, catastrophic events.
