Earthquakes and Volcanic Eruptions

Timeline created by tothtech21
  • Mt Vesivius Eruption 1631

    On 10th December 1631 residents of Torre del Greco stated they heard the mountain roaring from the inside, with such a stirring of subterranean spirits, that they could hardly sleep at all during the night. This was the first activity at Mt Vesuvius in 500 years. A large eruption of Mt Vesuvius began at dawn on 16th December 1631. A Plinian column erupted up to 28 km high accompanied by tephra fallout for a few hours. Tephra fallout occurred on the eastern side of the volcano, sparing Naples.
  • Cascadia Earthquake

    On January 26, 1700, what is now the US Pacific Northwest was shaken by a Magnitude 9.0 earthquake. Oral traditions tell of collapsed houses, from shaking that was so stong that people could not stand. The quake caused many landslides. A tsunami was created that destroyed at least one village. However, since the people living in the area did not have a written language, so what we know of the quake is from sketchy oral tradition and traces left in the geological record.
  • Libson Earthquake

    On November 1, 1755, Lisbon, Portugal was shaken by a large earthquake just offshore. Lisbon was not only a city of 250,000 people but the capital of the Portuguese empire, which spread around the world. It was one of the most important cities in Europe. Although Portugal had been hit by quakes in the past it had been 200 years since the last major earthquake. The quake hit at 9:40 AM on All Souls Day. outside.
    The quake triggered
  • Mt Pericutan Eruption 1759-1774

    Subterranean noises were first heard in late June of 1759, increasing by 17th September. On 29th September several earthquakes were felt and a dark cloud erupted from Cuitinga Creek. Phreatic and phreatomagmatic activity occurred in the initial stages of the eruption and covered the surrounding area with sticky mud. Incandescent bombs began to be ejected on 8th October 1759. Violent eruptions continued through 1764, the year of greatest activity, and lesser eruptions.
  • Mt Vesiveus Eruption 1794

    An explosion occurred at the summit of Mt Vesuvius on 15th July 1794. A lava flow reached Torre del Greco at 6:00 am the following morning destroying a large part of the town.
  • New Madrid Earthquake

    The New Madrid quakes were actually three great quakes, each of which probably measured over 8.0 on the Richter Scale. They occured from December 16, 1811 to February 7, 1812. They were largest earthquakes in the history of the contiguous United States. Estimated at over Magnitude 8.0 on the Richter Scale, they were felt over most of the Eastern United States, as much as 1,000 miles from the epicenter, just west of the Mississippi.
  • Mt Vesivius Eruption 1834

    An eruption of Vesuvius began on 23rd August 1834 and discharged a large amount of lava. On 24th August a new vent opened on the eastern side of the volcano at Grotta del Mauro, in the location of the 1817 lava flow. On 27th August a lava flow moved towards Mauro, widening as it descended, and reached a width of half a mile, and a depth of 18 feet. The lava flow destroyed 180 houses, leaving 800 people homeless, and covered 500 acres of land.
  • Mt Vesivius Eruption 1858

    On 28th May 1858 lava flowed from six fissured on the northwest side of Mt Vesuvius volcano. Lava continued to flow until 1861 and reached Fosso Grande, Piano delle Ginestre and Fosso della Vetrana.
  • Mt Vesivius Eruption 1861

    A series of earthquakes preceded an eruption of Vesuvius on 6th December 1861. A fracture opened 2 km NE of Torre del Greco, and could be seen from the sea. Eruptive vents opened on the upper part of the fracture killing one woman. Lava flowed towards Torre del Greco and Herculanem until the end of December and destroyed several houses. The coastline rose up to one metre. Carbon dioxide emissions occurred in wells and cellars.
  • Mt Vesivius Eruption 1872

    On 26th April 1872 an eruption began at Vesuvius with lava flowing from a fissure on the northwestern side of the mountain. The lava blocked the escape route for 20 spectators who were killed. The lava flow forked at Observatory Hill. One flow passed through Fossa della Vetrana and Fossa Faraone and destroyed the inhabited centres of Masa and S Sebastiano al Vesuvio. The second fork of the lava flow surrounded the Volcano Observatory and stranded staff for days.
  • 1975 Haicheng Earthquake

    The Haicheng quake is the most successfully predicted earthquake in history. Authorities evacuated the city of 1 million people days before this powerful 7.0 magnitude quake hit on February 4, 1975 at 11:36 UTC (7:36 pm local time). Although over 2,000 people were killed, authorities estimate that over 150,000 fatalities could have occured without the evacuation.
  • Japanese Tsunami 1896

    June 15, 1896, 10:30 UT, 34N36, 144E12: Sanriku on the island of Honshu on Japan's Pacific seaboard - An earthquake measuring 7.6 on the Richter scale unleashed a tsunami causing a death toll of more than 27,000.
  • Mt Peelee Eruption 1902

    Jan 31, 1906, 15:36 UT, 1N00, 81W30: Ecuador - an earthquake registering 8.8 on the Richter scale off the coasts of Colombia and Ecuador produced a tsunami claiming about 1,000 lives.
  • Mt Vesuvius Eruption 1906

    An eruption began at Mt Vesuvius on 4th April 1906 when an effusive vent opened on the southern slope at an altitude of 1200 m, near Casotto delle Guide. At midnight on 4th April the lava flow ceased when a new fracture opened up near the cistern of Casa Fiorenza at an elevation of about 800 m elevation. At about 8:00 a.m. on 6th April a third vent opened near Bosco Cognoli at 600 m altitude on the same fracture zone.
  • 1906 San Fransico Earthquake

    The California earthquake of April 18, 1906 ranks as one of the most significant earthquakes of all time. Today, its importance comes more from the wealth of scientific knowledge derived from it than from its sheer size. Rupturing the northernmost 296 miles (477 kilometers) of the San Andreas fault from northwest of San Juan Bautista to the triple junction at Cape Mendocino, the earthquake confounded contemporary geologists with its large, horizontal displacements and great rupture length.
  • Mt Paricutin Eruption 1943

    Paricutin was born on February 20, 1943 when a fissure opened on the lands of Rancho Tepacua. At 10:00 hr subterranean noises were heard and at 16:00 hr thunderous noises accompanied the opening of the first fissure. The earth was described as rising like a wall 1 m high, 10 m long, and 2 m wide. by midnight on the first day the cone at Paricutin had reached a height of 6m. By afternoon of 21st February a 50 m high cone had formed and was ejecting bombs 500 m high.
  • Mount Vesuvius Eruption

    A two week long eruption of Mt Vesuvius volcano began on 18th March 1944 with a lava flow from the summit crater. Eruptions changed to explosive activity on 21st March with eight lava fountains. The lava fountains increased with time, and the last one on 22nd March was the most intense, reaching heights of 1000 m. A transition to mixed magmatic–phreatomagmatic activity was marked by emissions of ash columns.
  • Mt Lamington Eruption 1951

    Three days of tremor preceded the eruption at Mt Lamington volcano. Landslides, ash emission, glowing volcanic bombs and lightning were witnessed and ignored by the people living around the volcano. Media reports stated officials did not to tell the the volcanologists about the activity and discouraged locals from leaving the area. The paroxysm at Lamington occurred at 10:40 am on the 21st January 1951. A roar was heard 320 km away and a catastrophic avalanche ripped apart the side of the mount.

More than 2,300 people died.
  • Mt Bezymianny Eruption 1955

    On 29th September 1955, the first earthquake was recorded beneath Bezymianny volcano. The volcano was wakening after being dormant for 1000 years. From 19th October, earthquakes occurred at a rate of hundreds per day. An eruption commenced on October 22 with strong Vulcanian explosions from a new summit crater. The Vulcanian activity continued during November and the eruptions produced large quantities of ash. The duration of the pre-climactic stage was five months.
  • Dale City Earthquake

    On 22 March 1957, the San Francisco Peninsula was rocked by an earthquake centered in the Daly City area that caused damage in Westlake District of that city, and some damage in San Francisco. Although only magnitude 5.3, this was the largest earthquake on the Peninsula since 1906. Recent work which has attempted to find the epicenter of the 1906 San Francisco earthquake has suggested an epicenter on or near the Peninsula.
  • Southern Chile Tsunami 1960

    May 22, 1960, 19:11 UT, Southern Chile, 39S30, 74W30: A 9.5 strong earthquake was followed by a devastating tsunami affecting Pacific rim countries including the Philippines and Japan. The death toll was 5,700 in Chile, 61 in Hawaii and 130 in Japan.
  • Mt Vesivius Eruption 1960

    On 27th December 1760 a fracture opened up 3 km northwest of Boscotrecase on the southern side of Vesuvius. Fifteen vents opened and effused a large amount of lava. The cone of the central crater collapsed on 29th December diminishing the eruption.
  • 1964 Alaska Earthquake

    The Great Alaska Earthquake that struck the Anchorage area on Good Friday, March 27, 1964 at 5:36 PM registered 8.6 on the Richter Scale, although scientists now favor a different magnitude scale for very large quakes that shows this quake as 9.2. This made it the largest quake that has hit the United States in recorded history and one of the largest known worldwide. Geologically, the effects were widespread and dramatic.
  • 1976 Tangshan Earthquake

    The 7.5 Magnitude Tangshan earthquake struck on July 27, 1976 at 19:42 (GMT), (July 28, 3:42 AM local time). Tangshan is a densely poplulated industrial city of a million people 90 miles east of Bejing. The intitial quake was followed by a major aftershock 15 hours later. Official estimates put the death toll at over 240,000, although unofficial sources estimates run as high at 655,000, with 800,000 injuries. This is the greatest death toll recorded for an earthquake in the last 400 years.

  • Mt Ruiz Eruption 1985

    On 13th November 1985 an eruption of Ruiz caused a lahar which swept through the town of Armero killing 25 000 people. Lahars have the consistency of freshly made concrete. The government officials were responsible for this tragedy as they chose to ignore the warnings by volcanologists. Fumarolic, phreatic and seismic activity had occurred at the volcano for a year before the eruption.
  • Mt Bezymianny Eruption 1986

    During the night of June 22/23 the fourth lava flow after the 1985 eruption began to form. The lava flow ceased on 26th June. During the eruption two pyroclastic flows occurred and traveled up to 2 km long. The temperature of the ash-block flow deposits was about 300°C.

    The 6.7 Magnitude Northridge Earthquake struck early in the early morning of January 17, 1994 at 4:31 AM. The Epicenter was in Northridge, California, a suburb of Los Angeles in the San Fernando Valley. This same general area had been hit by a 6.6 Magnitude quake in 1971. It was one of the most expensive natural disasters in US history, with total damage estimated at $15 billion. The death toll of 57 and 1500 serious injuries is considered low for a quake of this size in a heavily populated area
  • 1995 Kobe Earthquake

    This 6.9 Magnitude earthquake on January 16, 1995 in Kobe, Japan caused extensive damage and loss of life. It has been studied extensively, especially in relation to the Northridge Earthquake in Southern California, almost exactly one year earlier. Both earthquakes had similar magnitudes and resulted from similar faults. The damage in Kobe, however was much worse than in Northridge. One major difference was in the different construction of buildings in California and Japan.
  • Mt Bezimianny Eruption 1997

    There was very little seismic activity prior to the 1997 eruption. The volcano began activity on 19th April 1997 with detection of volcanic tremor. By 8th May continuous tremor was recorded, which corresponded to the extrusion of a spine through the upper part of the dome. On 9th May an explosion produced a 14 km high eruption plume which drifted 600 km NE. Strong explosive activity lasted about 37 min. The eruption destroyed the top of the dome, forming a funnel-shaped crater 200 m across.
