The Pinatubo eruption on 15 June 1991 was the second largest volcanic eruption of the 20th century. Pinatubo is a complex of lava domes located 100 km NW of Manila city, Luzon Island, Philippines. Prior to the eruption, Pinatubo was a little known volcano and it had been dormant for 400 years.

Pinatubo injected about 15 million tons of sulfur dioxide into the stratosphere, where it reacted with water to form a hazy layer of aerosol particles composed primarily of sulfuric acid droplets. In the case of Mount Pinatubo, the result was a measurable cooling of the Earth’s surface for a period of almost two years.

Botolan (population 51,675), the largest town in Zambales and closest to Pinatubo, also has the largest Aeta population in the province.

It is a subduction-related volcano, formed by the Eurasian Plate sliding under the Philippine Mobile Belt along the Manila Trench to the west. Molten material related to the complex tectonics associated with the subducting slab, rises through the lithosphere and generates the volcanism typical of subduction.

The volcano erupted on the afternoon of January 12, 2020, 43 years after its previous eruption in 1977. According to PHIVOLCS director Dr. Furthermore, Solidum confirmed that there was a magmatic intrusion that was driving the volcano’s unrest.

Scientists have talked about what could happen if Yellowstone’s supervolcano were to erupt in a modern-day setting throughout the United States. One scientist spoke to medically daily and reported that scientists predict that 5 billion people in total would die as a result of an eruption.

If the supervolcano underneath Yellowstone National Park ever had another massive eruption, it could spew ash for thousands of miles across the United States, damaging buildings, smothering crops, and shutting down power plants.

The Yellowstone Volcano is known to be a supervolcano because in the past (2 million years ago) it released over 600 cubic miles of lava and ash in one single event. When the last eruption took place about 640,000 years ago it is believed that it caused the last ice age.

At least five major ice ages have occurred throughout Earth’s history: the earliest was over 2 billion years ago, and the most recent one began approximately 3 million years ago and continues today (yes, we live in an ice age!). Currently, we are in a warm interglacial that began about 11,000 years ago.

A supervolcano in the heart of America’s northwest has the potential to blanket the US in a ‘nuclear winter’. If it were to erupt, the Yellowstone supervolcano would be one thousand times as powerful as the 1980 Mount St Helens eruption, experts claim.

A massive volcanic eruption 250,000 years ago shot dust and ash into the atmosphere and probably caused a winter like that expected by many scientists to follow a nuclear war, according to New Zealand geologists. The New Zealand experts say the Taupo eruption was 1,000 times greater than the 1982 explosion of Mt.

Some conspiracy theorists have claimed a Yellowstone eruption could be triggered by a nuclear bomb, but is this the case? The short answer, according to the United States Geological Survey (USGS), is a resounding no.

In a nuclear attack, the detonation would occur above ground, so the majority of the energy would be released into the air. So in conclusion, nothing would happen and Yellowstone would not erupt if for some reason a nuclear bomb was detonated near the supervolcano.

The explosion of the bomb mixed with the build-up of pressure inside a volcano could amplify the eruption. The force would release even more ash and lava, spreading it even further than it would’ve gone with the volcano’s own power. As cool as it sounds on paper, nuking a volcano just won’t work.

Michael Poland, USGS geophysicist specializing in seismology and volcanic activity at Yellowstone National Park, said: “There’s always rumors about Yellowstone erupting. “[Earthquakes] don’t trigger eruptions. They don’t trigger volcanic activity.

No, earthquakes of magnitude 10 or larger cannot happen. That is, the longer the fault, the larger the earthquake. A fault is a break in the rocks that make up the Earth’s crust, along which rocks on either side have moved past each other.

Yellowstone is one of the most seismically active areas in the United States. Approximately 700 to 3,000 earthquakes occur each year in the Yellowstone area; most are not felt.
