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.

Answer: 10, 100
Explanation:
Magnitudes are based on a logarithmic scale (base 10). For each whole number you go up, the amplitude of the ground motion recorded by a seismograph goes up ten times. Using this scale, a magnitude 5 earthquake would result in ten times the level of ground shaking as a magnitude 4 earthquake (and 32 times as much energy would be released).
1 unit increase corresponds to 10 fold increase in magnitude.

According to the graph, the prediction on the future is that there will be c. resource depletion.
<h3>What does the graph show?</h3>
The graph shows that as time goes on, humanity will demand more and more hectares of forest.
This will lead to forests eventually being wiped out after around 700 years which points to resource depletion.
