What was the Richter scale of the eruption in Monserrat in 1995?
The eruption in Montserrat in 1995 was a catastrophic event but it did not have a specific Richter scale measurement because the scale is typically used to measure earthquakes, not volcanic eruptions. Instead, volcanic eruptions are typically measured using the Volcanic Explosivity Index (VEI) which gives a sense of the eruption's intensity and explosiveness.
What was the Krakatoa eruption on the Richter scale?
The Krakatoa eruption in 1883 is estimated to have been around 6 to 7 on the Volcanic Explosivity Index (VEI), which is used to measure the intensity of volcanic eruptions. The Richter scale, which measures the magnitude of earthquakes, is not typically used to measure volcanic eruptions.
How far did the ash go up into the atmosphere from the eruption?
The ash from volcanic eruptions can reach altitudes of up to 20-30 kilometers into the atmosphere. The exact height can vary depending on the size and intensity of the eruption.
What natural phenomenon occurs when magma breaks through the earths crust?
When magma breaks through the earth's crust, it results in a volcanic eruption. This can lead to the release of lava, ash, gases, and rock fragments onto the surface. Volcanic eruptions can vary in intensity and have the potential to cause widespread destruction and impact local ecosystems.
What happens to the number and intensity or small earthquakes just before an eruption?
Before a volcanic eruption, there is often an increase in the number and intensity of small earthquakes, a phenomenon known as volcanic seismicity. This occurs as magma rises towards the surface, causing pressure to build up and fractures to form in the surrounding rock. The increased seismic activity can serve as a warning sign of an impending eruption, indicating that the volcano is becoming more active. Monitoring these earthquakes helps volcanologists assess the likelihood and timing of an eruption.
What determined how strong a volcanic eruption will be?
The viscosity of the magma
Before a volcanic eruption seismic activity seems to?
increase in both frequency and intensity
What is the significance of the Krakatoa eruption sound recording in understanding the impact of the volcanic eruption?
The Krakatoa eruption sound recording is significant because it provides a firsthand audio record of the powerful explosion and its impact on the environment. By analyzing the recording, scientists can better understand the intensity and scale of the volcanic eruption, helping to improve our knowledge of volcanic activity and its effects on the surrounding area.

What word that mean a volcanic explosion?
A volcanic explosion is an eruption.
What is volcanic throat?
it is the upperpart of the volcanic chimney during an eruption it is the upperpart of the volcanic chimney during an eruption
What is the significance of the Krakatoa sound recording in understanding the volcanic eruption's impact on the environment and surrounding areas?
The Krakatoa sound recording is significant because it provides valuable information about the intensity and reach of the volcanic eruption. By analyzing the sound waves captured in the recording, scientists can better understand the impact of the eruption on the environment and surrounding areas, helping to improve our knowledge of volcanic activity and its effects.

When magma escapes from the mantle to the sufrface of earth it causes a?
