The average lead time for a tornado warning in the U.S. is 14 minutes. Depending on the scale of the event, the potential for a tornado outbreak can be detected up to a week or so in advance.
Volcanoes are trickier. Although signs of activity can be detected months or even years before an eruption, we still cannot predict when an eruption will occur.
What else can I help you with?
Why does volcanoes have too much lava coming out?
Lava erupts out of a volcano because of the pressure building up in the magma below.
How explosively or quietly a volcano erupts is not affected by?
If a volcano erupts more explosively, the lava spewing out tends to reach farther, possibly ruining a near by town. If it erupts more quietly, not as much lava tends to spew out. However, any eruption will cause harm to the atmosphere because it releases harmful pollutants.

What happens in each stage of a volcano?
Active Stage: Volcano erupts, releasing lava, ash, and gases. Dormant Stage: Volcano is not erupting but can become active again. Extinct Stage: Volcano is unlikely to erupt again in the future.
What steps can be taken to reduce the risks of volcanic eruptions?
Sadly, volcano eruptions cannot be reduced or prevented as this is part of nature's occurrence. However, damages caused by volcanic eruptions can be reduced and prevented. For example, evacuation of people during volcano eruption warnings can save lives before the volcano erupts. Property can also be situated further away from the volcano to prevent as much economic losses and so on.
What are you doing before volcano erupts?
Before a volcano erupts, people are just living their lives, going about their daily routines. There typically wasn't much warning before a major eruption, and there still isn't a good early detection and warning system.
How viscosity affect volcanic eruptions?
Viscosity is how thick the magma is and this can impact on how much a volcano erupts and how it flows.
How much rain does the Patagonian Desert get in a year?
in thePatagonian desert it rains alot and when the volcano erupts it rains even more

Why is rhyolite found in Yellowstone National Park?
Yellowstone is the site of a very large volcano that is often referred to as a supervolcano. Much of what it erupts is rhyolite.

How much time did people have to evacuate before Mount Etna erupted?
It can vary depending on the eruption, but typically people have a few hours to evacuate before Mount Etna erupts. The volcano usually displays warning signs such as increased seismic activity, gas emissions, and surface deformation before an eruption, giving authorities time to implement evacuation measures.
What causes an underwater volcano erupts?
Volcanoes underwater erupt in much the same way as those on dry land. They erupt when pressure builds up. The difference between these two types of volcanoes is that the lava produced in an underwater volcano cools dramatically faster than the lava on land.
Why do rocks fly out of volcanoes?
Rocks fly out of volcanoes during eruptions due to the build-up of pressure from the molten rock, gas, and steam inside the volcano. When the pressure becomes too high, the volcano erupts, causing rocks and other materials to be forcefully expelled through the vent.
