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.

The answer is b. Constitutional monarchy. I know this because all of the other ones are examples of other types of governments. This is the only one that is a true cross between the two
i want to say it is D. because i believe that they are nocturnal animals and they are found in deserts.
Answer:
Explanation:
Given that:
Area = 475 acres
The length of the channel (L) = 6870 feet
The average water shield slope (S) = 100 feet/mile
Since; 1 mile = 5280 feet
Burst duration D = 15 min
∴
100 feet/mile = 100/5280
The average water shield slope (S) = 5/264
Using hydrograph method:
The time of concentration 
where;
L = 6870
S = 5/264
min
Since 60 min = 1 hour
32.34 min will be (32.34*1)/60
= 0.539 hour
Lag time 
The time to peak i.e
Since D = 15 min is not equal to 
, then we hydrograph apart from duration lag time.
Then;
Now, we need to determine the peak discharge 
by using the formula:
where
484 = peak factor
Recall that A = 475 acres, to miles, we have:
A = 0.7422 mile²
∴
