chernobyl nuclear disaster #1
the Chernobyl nuclear disaster began in the early hours of Saturday 26 April 1986 within the Chernobyl nuclear power plant. an explosion and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR (soviet union) and Europe. it is considered the worst nuclear power plant accident in history and is one of only two classified level 7 event on the International Nuclear Event Scale. The other being the Fukushima nuclear disaster in 2011. -
chernobyl nuclear disaster #2
the disaster began during a system test reactor number four of the Chernobyl plant. there was a sudden surge of power output, and an emergency shut down was attempted a more extreme spike in power output occurred, which led a reactor vessel to rupture and a series of explosions. these events exposed the graphite moderator of the reactor to air, causing it to ignite. the resulting fire sent a plume of highly radioactive smoke into the atmosphere and over an extensive geographical area. -
mt. st. Helens eruption #1
At 8:32 a.m. on may 18, 1980, the volcano located in southern Washington called Mt. St. Helens erupted, sending a massive avalanche and killing 57 people, and ash from the eruption fell as far as Minnesota. Seismic activity at Mt. St. Helens, which is about 96 miles south of Seattle, began on march 16. A 4.2-magnitude tremor was recorded four days later and then, on march 23-24, there was 174 different recorded tremors. -
chernobyl nuclear disaster #3
nearly 400 million people resided in territories that were contaminated with radioactivity at a higher level than 4 kBq/m2 (0.11 Ci/km2) from April to July 1986. nearly 5 million people (including, more than 1 million children) still alive with dangerous levels of radioactive contamination in Belarus, Ukraine, and European Russia -
Mt. St. Helens eruption #2
The first eruption occurred on march 27, when a 250-foot wide vent opened up at the top of the mountain. Ash was blasted 10,000 feet in the air, some of which came down nearly 300 miles away in Spokane. The ash caused static electricity and lightning bolts. Authorities issued a hazard watch for a 50-mile radius around the mountain. -
Mt. St. Helens eruption #3
The National Guard set up road blocks to prevent access to the area, but these were easily avoided by using the region’s unguarded logging roads. Many residents of the area evacuated, but a substantial number refused. Harry Truman, 84—no relation to the former president—was one resident who refused to move and, after receiving a great deal of positive media coverage for his decision, became a national icon as well as, later, the subject of a local memorial. -
Hubble space telescope #1
On April 24, 1990, after years of false starts and delays, the Hubble space telescope was launched into low-earth orbit as part of a multi billion-dollar project led by NASA and the European Space Agency. The bus-sized observatory is equipped with an 8-foot-wide focusing mirror and an array of cameras capable of seeing visible, infrared and ultraviolet light, and its eye popping images have provided scientists and amateur astronomers alike with a glimpse into the inner workings of the universe. -
Hubble space telescope #2
The Hubble telescope was responsible for the deepest images of the universe. In late-1995, Hubble's operators allowed the telescope to star for 10 days at a seemingly empty sliver of sky. many doubted whether the lengthy exposure would be of value, but the resulting image, known as the "Hubble deep field," was astonishing. by looking beyond the milky way, it revealed a plethora of never-before-seen galaxies, including some of the most distant star systems ever discovered. -
Hubble space telescope #3
astronomers repeated the experiment with 2004's "Ultra deep field," and they have since released several more images that used infrared and combined exposures to peer farther into space than ever before. Some of the images as far as 13.2 billion light years away. Since the light from these galaxies has taken eons to reach our solar system, it offers astronomers a window onto what the universe looked like only a short time after the Big Bang some 13.7 billion years ago. -
9/11 disaster
on September 11, 2001, 19 militants associated with the Islamic extremist group al-Qaeda hijacked four airliners and carried out suicide attacks against targets in the United States. two of the planes being flew into the towers of the world trade center in new york, NY, a third plane flown into the pentagon just outside Washington, D.C., and the fourth plane flew into a field in Pennsylvania. Often referred to as 9/11, the attacks lead to major damage and tragedy. -
9/11 disaster
American Airlines Boeing 767 loaded with 20,000 gallons of jet fuel crashed into the north tower of the World Trade Center in New York City. The impact left a gaping, burning hole near the 80th floor of the 110-story skyscraper, instantly killing hundreds of people and trapping hundreds more in higher floors. As the evacuation of the tower and its twin got underway, television cameras broadcasted live images of what initially appeared to be a freak accident. -
