Because The Philippine Institute of Volcanology and Seismology (PHIVOLCS) who were people who studied the mountain realised that it was going to erupt and they evacuated loads of people
Mt. Pinatubo is 1.6 miles wide. The last eruption took place on June 15, 1991. The volcano is located in the Philippines.
Mount Pinatubo, located in the Philippines, is classified as a stratovolcano and is known for its significant eruption in June 1991, one of the largest in the 20th century. The frequency of eruptions at Mount Pinatubo has varied, with its last major eruption occurring in 1991 after a period of dormancy since 1970. Historically, it has erupted several times, with the most notable events occurring every few hundred years. The volcano remains closely monitored for any signs of activity.
Mount Pinatubo, located in the Philippines, is a stratovolcano known for its significant eruptions, particularly its catastrophic eruption in June 1991, which was one of the largest volcanic events of the 20th century. Prior to 1991, it had been dormant for about 600 years, with the last known eruption occurring in 1586. Post-1991, the volcano has shown intermittent activity, including minor eruptions and volcanic earthquakes, but has largely remained quiet. Overall, its eruption frequency is irregular, with significant events occurring roughly every few hundred years.
The eruption of Mount Pinatubo in 1991 injected sulfur dioxide gas into the stratosphere. This gas combined with water vapor to form sulfate aerosols, which scattered sunlight in the atmosphere and resulted in colorful sunrises and sunsets.
The Novarupta volcano eruption in 1912 is estimated to have directly caused the deaths of few to no individuals since the area was sparsely populated. However, indirect deaths due to famine, starvation, and other factors following the eruption are not well-documented.

The June 12-15, 1991, eruption of 1475m Pinatubo volcano, located 100 kilometers northwest of Manila in the Philippines, was one of the largest eruptions of this century and it strongly effected some aspects of our climate.In total the Pinatubo eruption discharged 5 billion cubic meters of ash and pyroclastic debris (including 20 to 30 megatons of sulphur dioxide and aerosols) into the atmosphere via eruption columns which were 18km wide at the base and had heights of up to 30km.

The secondary effects of the Mt. Pinatubo eruption in 1991 included widespread ashfall, lahars (mudflows), and pyroclastic flows that caused destruction of homes, infrastructure, and agricultural land. The eruption also led to a temporary cooling of the Earth's atmosphere due to the release of sulfur dioxide, which resulted in global temperatures dropping by about 0.5°C for a few years.
No eruption has ever killed 100,000 billion people; bear in mind that the total population of the planet Earth is less than 7 billion. Even the most destructive eruption in history (probably the Thera eruption) probably did not kill more than a few thousand people.
None. They were all dead. Very few escaped the eruption .

At first most of the plants die due to the heat and gasses, but then they will come back since they grow well in a volcanic soil. There is a tree that is still alive after the eruption of Pompeii in 79 AD.
I believe it was Yellowstone. If I remember correctly, The eruption was around 2500 times larger than the mount st. Helens eruption a few years ago. We are around 46,000 years over due for an eruption.
Most of the people were surprised by the eruption and died. Only those few that left immediately, survived.http://www.bbc.co.uk/history/ancient/romans/pompeii_portents_01.shtml
