The first notable volcanic activity since 1992-93, when there was dome growth and secondary phreatic explosions in the aftermath of the major 1991 eruption, is a phreatic explosion from the summit crater lake at Pinatubo in November 2021.
<h3>What evidence exists to suggest that the 1991 eruption of Mount Pinatubo rendered lahar unsafe?</h3>
Lahars at Pinatubo since 1991 In the years that followed the devastating eruption in 1991, they deposited more than 0.7 cubic miles (3 cubic kilometers; hundreds of square miles of land were submerged by the debris, which was the equivalent of 300 million dump truck loads, in the lowlands surrounding the volcano.
<h3>How were they aware of the impending eruption of Mount Pinatubo?</h3>
Seismic data and an increase in sulfur dioxide released from the volcano by May 1991 suggested to scientists that the volcano's magma chambers were being filled with new magma. The rapidly expanding lava dome on Pinatubo hinted at a forthcoming large-scale eruption.

Tanisha is not correct.
<u>Explanation</u>:
When the moon is closest to the sun, the light coming from the sun is blocked by the moon that is why moon’s shadow fall on the earth, thus moon looks dark i.e. solar eclipse. When the moon is furthest from the sun, the light coming from the sun cannot reach the moon as it is blocked by earth thus moon looks dark from earth i.e. lunar eclipse.
The only disadvantage I could think of would be price of equipment needed to produce energy from the source (i.e. price of solar panels)
Answer:
True
Explanation:
The fourth methods outlined in the paragraph are useful to determine the nature of the differences between the geology of northern and southern Arizona.
This is because these geology differences can manifest in seismic profiles, in geologic history (for example, the differences in the rock formations that form the soil of the two regions), in drill core studies, and also, in a detailed map of the geology of the state, where ideally, the results from the previous studies would be mapped.
