Earthquake
An earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth's crust that creates seismic waves.
Tsunami
A tsunami also called a tsunami wave train, and at one time incorrectly referred to as a tidal wave, is a series of water waves caused by the displacement of a large volume of a body of water, usually an ocean, though it can occur in large lakes.
Tornado
A tornado (often referred to as a twister or, erroneously, a cyclone) is a violent, dangerous, rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud.
Floods
A flood is an overflow of an expanse of water that submerges land. The EU Floods directive defines a flood as a temporary covering by water of land not normally covered by water
Volcanic Eruptions
Volcanoes can cause widespread destruction and consequent disaster through several ways. The effects include the volcanic eruption itself that may cause harm following the explosion of the volcano or the fall of rock.
Tsunami 1800s
6:12 AM
1833: Sumatra, Indonesia
On 25 November 1833, a massive earthquake estimated to have been between 8.8-9.2 on the moment magnitude scale, struck Sumatra in Indonesia. The coast of Sumatra near the quake's epicentre was hardest hit by the resulting tsunami.
1854: Nankai, Tokai, and Kyushu Japan
The Ansei Quake which hit the south coast of Japan, was actually set of 3 quakes, two magnitude 8.4 quakes and a 7.4 quake all in 3 days.
- The first on Nov 4, 1854 near what is today Aichi Prefecture and Shizuoka Prefecture with tsunami.
- It was followed by another 8.4 the next day in Wakayama Prefecture, Earthquake generated a maximum wave of 28 meters at Kochi, Japan, and the earthquake that tsunami killed 3,000 people. The tsunami washed 15,000 homes away. The number of homes destroyed directly by the earthquake was 2,598; 1,443 people died.
- The third was a 7.4 quake on Nov 7, 1854 in Ehime Prefecture and Oita Prefecture.
The total result was 80,000-100,000 deaths.
1855: Edo, Japan
The following year, the 1855 Great Ansei Edo Quake hit (Tokyo region), killing 4,500 to 10,000 people. Popular stories of the time blamed the quakes and tsunamis on giant catfish called Namazu thrashing about. The Japanese era name was changed to bring good luck after 4 menacing quake/tsunamis in 2 years.
1868: Hawaiian Islands
On April 2, 1868, a local earthquake with a magnitude estimated between 7.5 and 8.0 rocked the southeast coast of the Big Island of Hawaiʻi. It triggered a landslide on the slopes of the Mauna Loa volcano, five miles north of Pahala, killing 31 people. A tsunami then claimed 46 additional lives. The villages of Punaluu, Ninole, Kawaa, Honuapo, and Keauhou Landing were severely damaged and the village of ʻĀpua was destroyed. According to one account, the tsunami "rolled in over the tops of the coconut trees, probably 60 feet high .... inland a distance of a quarter of a mile in some places, taking out to sea when it returned, houses, men, women, and almost everything movable." This was reported in the 1988 edition of Walter C. Dudley's book "Tsunami!" (ISBN 0-8248-1125-9).
1868: Arica, Chile
On August 16, 1868, an earthquake with a magnitude estimated at 8.5 struck the oceanic trench currently known as the Peru-Chile Trench. A resulting tsunami struck the port of Arica, then part of Peru, killing an estimated 25,000 in Arica and 70,000 in all. Three military vessels anchored at Arica, the US warship Wateree and the storeship Fredonia, and the Peruvian warship America, were swept up by the tsunami.
1883: Krakatoa, Sunda Strait, Indonesia
The island volcano of Krakatoa in Indonesia exploded with devastating fury on August 26–27, 1883, blowing its underground magma chamber partly empty so that much overlying land and seabed collapsed into it. A series of large tsunami waves was generated from the collapse, some reaching a height of over 40 meters above sea level. Tsunami waves were observed throughout the Indian Ocean, the Pacific Ocean, and even as far away as the American West Coast, and South America. On the facing coasts of Java and Sumatra the sea flood went many miles inland and caused such vast loss of life that one area was never resettled but reverted to the jungle and is now the Ujung Kulon nature reserve.
1896: Meiji Sanriku, Japan
On 15 June 1896, at around 19:36 local time, a large undersea earthquake off the Sanriku coast of northeastern Honshū, Japan, triggered tsunami waves which struck the coast about half an hour later. Although the earthquake itself is not thought to have resulted in any fatalities, the waves, which reached a height of 100 feet, killed approximately 27,000 people. In 2005 the same general area was hit by the 2005 Sanriku Japan Earthquake, but with no major tsunami.
