    Earth was formed

    Earth was formed
    Earth was formed about 4.5 billlion years ago. Also made the third planet from the sun. Earth's rocky core formed first, with heavy elements colliding and binding together. Dense material sank to the center, while the lighter material created the crust. The planet's magnetic field probably formed around this time. Gravity captured some of the gases that made up the planet's early atmosphere. And as we know this is how earth was formed.

    Pangea

    Pangea
    About 300 million years ago, Earth didn't have seven continents, but instead one massive supercontinent called Pangaea, which was surrounded by a single ocean called Panthalassa. DescriptionPangaea or Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from earlier continental units approximately 335 million years ago, and it began to break apart about 175 million years ago. Pangaea was the most recent supercontinent. This was amazing.

    Pompeii

    Pompeii
    Pompeii was an ancient Roman city near modern Naples in the Campania region of Italy, in the territory of the comune of Pompei. Pompeii, along with Herculaneum and many villas in the surrounding area, was buried under 4 to 6 m of volcanic ash and pumice in the eruption of Mount Vesuvius in AD 79. Mount Vesuvius, on the west coast of Italy, is the only active volcano on mainland Europe. It is best known because of the eruption in A.D. 79 that destroyed the cities of Pompeii. Vesuvius killed many.
  • Lisbon, 1755

    Lisbon, 1755
    The 1755 Lisbon earthquake, also known as the Great Lisbon earthquake, occurred in the Kingdom of Portugal on the morning of Saturday, 1 November, Feast of All Saints, at around 09:40 local time. In combination with subsequent fires and a tsunami, the earthquake almost totally destroyed Lisbon and adjoining areas.The devastation caused many Portuguese to question their religious beliefs and the horrific event has shaped Lisbon's history ever since. This earthquake killed 50,000 people. Not cool.
  • The birth of seismology

    The birth of seismology
    Yet, an ultimate goal of seismology, namely, the prediction of earthquakes, is not forthcoming. ... Even after 1922, contributions made by applied mathematicians (Wiener, 1930; Lighthill, 1960), physicists (Jeans, 1923; Born, 1925; Foek, 1946), and engineers (La Coste, 1934), continued to play central roles in seismology. Beno Gutenberg, (born June 4, 1889, Darmstadt, Ger.—died Jan. 25, 1960, Los Angeles, Calif., U.S.), American seismologist noted for his analyses of earthquake waves. wow right.
  • The Great Fault

    The Great Fault
    The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers through California. It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip. Length: 1,200 km (750 mi)
    Cities: San Francisco, San Bernardino
    Plate: North American & Pacific
    Earthquakes: 1857, 1906 (Mw ≈7.8), 1957 (Mw 5.7), 1989 (Mw ≈6.9), 2004
    Movement: Dextral. as we know this is in California today. that a long fault. Amazing.
  • The kantoearthquake

    The kantoearthquake
    The date was September 1, 1923, and the event was the Great Kanto Earthquake, at the time considered the worst natural disaster ever to strike quake-prone Japan. The initial jolt was followed a few minutes later by a 40-foot-high tsunami. A series of towering waves swept away thousands of people. Then came fires, roaring through the wooden houses of Yokohama and Tokyo, the capital, burning everything—and everyone—in their path. This killed thousands of people. It changed peoples lives.
  • Mount Saint Helens

    Mount Saint Helens
    DescriptionMount St. Helens is an active stratovolcano located in Skamania County, Washington, in the Pacific Northwest region of the United States. It is 50 miles northeast of Portland, Oregon and 96 miles south of Seattle, Washington. The 1980 Mount St. Helens eruption was the most destructive in U.S. history. Fifty-seven people died, and thousands of animals were killed, according to USGS. More than 200 homes were destroyed, and more than 185 miles of roads were damaged. This was so horrible.
  • Long Beach earthquake

    Long Beach earthquake
    The 1933 Long Beach earthquake took place on March 10 at 5:54 P.M. PST south of downtown Los Angeles. The epicenter was offshore, southeast of Long Beach, California, on the Newport–Inglewood Fault. The earthquake had a magnitude estimated at 6.4 Mw, and a maximum Mercalli intensity of VIII. On March 10, 1933, at 5:54 p.m., an estimated magnitude-6.3 earthquake hit Southern California. The Long Beach earthquake killed 115 people and damaged buildings throughout the region. very bad day.
  • south Napa earthquake

    south Napa earthquake
    The 2014 South Napa earthquake occurred in the North San Francisco Bay Area on August 24 at 03:20:44 Pacific Daylight Time. At 6.0 on the moment magnitude scale and with a maximum Mercalli intensity of VIII, the event was the largest in the San Francisco Bay Area since the 1989 Loma Prieta earthquake.Total damage in the southern Napa Valley and Vallejo areas was in the range of $362 million to 1 billion, with one person killed and 200 injured. This was terrible. I would not want to be in that.
