Earthquakes that caused the greatest loss of life, while powerful, were deadly because of their proximity to either heavily populated areas or the ocean, where earthquakes often create tsunamis that can devastate communities thousands of kilometers away.

Volcanic eruptions are not rare, and the area is prone to earthquakes and tsunamis because of this.

The volcanic disturbance can often cause severe earthquakes, which in turn can also cause tsunamis.

The Philippines sit astride typhoon belt and are usually affected by 15 and struck by five to six cyclonic storms per year ; landslides ; active volcanoes ; destructive earthquakes ; tsunamis.

These stresses may cause earthquakes and tsunamis.

The Greek historian Thucydides suggested in 426 BC that tsunamis were related to submarine earthquakes, but the understanding of a tsunami's nature remained slim until the 20th century and much remains unknown.

Major areas of current research include trying to determine why some large earthquakes do not generate tsunamis while other smaller ones do ; trying to accurately forecast the passage of tsunamis across the oceans ; and also to forecast how tsunami waves would interact with specific shorelines.

The Sumatran region is not unused to tsunamis either, with earthquakes of varying magnitudes regularly occurring off the coast of the island.

In Japan, the community is well-educated about earthquakes and tsunamis, and along the Japanese shorelines the tsunami warning signs are reminders of the natural hazards together with a network of warning sirens, typically at the top of the cliff of surroundings hills.

several hurricanes in recent years ; frequent and severe droughts and floods ; occasional earthquakes ; rare tsunamis

The fast decomposition of such deposits is considered a geohazard, due to its potential to trigger landslides, earthquakes and tsunamis.

Mountainous and volcanic, Honshu has frequent earthquakes ( the Great Kantō earthquake heavily damaged Tokyo in September 1923, and the earthquake of March 2011 moved the whole island by while causing devastating tsunamis ); the highest peak is the active volcano Mount Fuji at, which makes it the world's 7th highest island.

Given the great depth of Lake Tahoe, and the locations of the normal faults within the deepest portions of the lake, modeling suggests that earthquakes on these faults can trigger tsunamis.

In the winter of 2005 and beginning of 2006, tsunamis and earthquakes devastated much of Southeast Asia and Pakistan.

Under the Broadcast Act, NHK is under the obligation to broadcast early warning emergency reporting in times of natural disasters such as earthquakes and tsunamis.

: Floods and landslides are common ; earthquakes ; tsunamis ; tropical cyclones

Increased volcanic eruptions, for example, increase the amount of dust in the atmosphere, lowering global temperature ; earthquakes in a body of water may produce tsunamis ; and the shortage of nuclear fuel for a nuclear power-dependent civilization may potentially trigger nuclear war.

Poseidon, as well as being god of the sea, was also known as the " Earth Shaker " because when he struck the earth in anger he caused mighty earthquakes and he used his trident to stir up tidal waves, tsunamis and sea storms.

Underwater earthquakes or volcanic eruptions do not normally generate such large tsunamis, but landslides next to bodies of water resulting from earthquakes can, since they cause a massive amount of displacement.

The Moro Gulf is also an area of significant tectonic activity with several fault zones in the region capable of producing major earthquakes and destructive local tsunamis, such as the devastating 1976 Moro Gulf Earthquake which killed over 5, 000 people and left over 90, 000 people homeless as it hit the coast of Mindanao.

Inevitably after events such as earthquakes and tsunamis, there is an immediate response by the aid agencies as relief operations get underway to try and restore basic infrastructure and provide the basic fundamental items that are necessary for survival and subsequent recovery.

typhoons, earthquakes, and severe flooding are quite rare.

: Occasional earthquakes, hurricanes along Atlantic coast ; frequent flooding of lowlands at onset of rainy season and landslides ; active volcanoes ( See Climate of Costa Rica ).

Natural hazards: prone to earthquakes, major flooding during the snow melt.

Pakistan is subject to frequent earthquakes which are often severe ( especially in north and west ) and severe flooding along the Indus after heavy rains ( July and August ).

* Natural hazards: flooding and earthquakes

More recently, the B ' nai B ' rith Disaster Relief Fund has responded to the 2010 earthquakes in Haiti and Chile, the 2011 Japan tsunami and the multiple tornadoes and subsequent flooding that hit six states in the South and Midwest in 2011.

Atlantis perished through flooding and submergence in 9, 564 BC, and its destruction is explained by claiming successive disturbances in the axial rotation of Earth which caused earthquakes which led to the sudden sinking of Atlantis.

The severity of the natural disasters preceding the tyrant's emergence was reduced, as a worldwide famine leading to cannibalism, and earthquakes and flooding in various European cities, had clearly not taken place.

Berlín was heavily damaged by flooding and landslides resulting from Hurricane Mitch in 1998 and by the earthquakes of January and February, 2001.

This can be brought on by landslides, a hurricane, earthquakes, or other natural disasters that influence flooding, but while a homeowner may, for example, have earthquake coverage, that coverage may not cover floods as a result of earthquakes.

Various phenomena like earthquakes, landslides, volcanic eruptions, floods and cyclones are all natural hazards that kill thousands of people and destroy billions of dollars of habitat and property each year.

Investigations can include the assessment of the risk to humans, property and the environment from natural hazards such as earthquakes, landslides, sinkholes, soil liquefaction, debris flows and rockfalls.

While many phantom islands appear never to have existed, a few ( such as, perhaps, Thompson Island or Bermeja ) may have been actual islands subsequently destroyed by volcanic explosions, earthquakes or submarine landslides, or low-lying lands such as sand banks that are no longer above water.

earthquakes most severe in south and southwest ; geologic structure and climate promote landslides

They are caused by earthquakes, landslides, volcanic explosions, glacier calvings, and bolides.

A natural disaster is a major adverse event resulting from natural processes of or effecting the Earth, for example floods, tsunami, tornadoes, hurricanes and cyclones, volcanic eruptions, earthquakes, heatwaves and droughts, wild fires, landslides, blizzards, ice storms and avalanches.

Tsunamis can be caused by undersea earthquakes as the one caused in Ao Nang, Thailand, by the 2004 Indian Ocean Earthquake, or by landslides such as the one which occurred at Lituya Bay, Alaska.

In addition to gradual processes such as erosion, earth movement caused by earthquakes or landslides or volcanoes can cause a differential in land heights which interfere with the natural course of a water flow, and result in waterfalls.

These earthquakes did not cause a significant loss of life or property, since the area is very sparsely populated, but they did trigger thousands of landslides.

They also faced constant upheaval from both physical and social disasters ( earthquakes and landslides ; wars and governments ).

Natural crises, typically natural disasters considered as ' acts of God ,' are such environmental phenomena as earthquakes, volcanic eruptions, tornadoes and hurricanes, floods, landslides, tsunamis, storms, and droughts that threaten life, property, and the environment itself.

Three experiments remained on Atlantis: Extreme Temperature Translation Furnace ( ETTF ), a new furnace design allowing space-based processing up to 871 degrees Celsius ( 1, 600 degrees Fahrenheit ) and above ; Commercial Protein Crystal Growth ( CPCG ) complement of 128 individual samples involving 12 different proteins ; and Mechanics of Granular Materials, designed to further understanding of behavior of cohesionless granular materials, which could in turn lead to better understanding of how Earth ’ s surface responds during earthquakes and landslides.

In the midst of a savage hand-to-hand battle, a volcano suddenly erupts: the entire area is stricken by earthquakes and landslides that overwhelm both tribes.

Such waves are distinct from tides, caused by the Moon and Sun's gravitational pull, tsunamis that are caused by underwater earthquakes or landslides, and waves generated by underwater explosions or the fall of meteorites — all having far longer wavelengths than wind waves.

Although these approaches were not always welcomed ( at least initially ) by specialists in the subjects examined, SOC has nevertheless become established as a strong candidate for explaining a number of natural phenomena, including: earthquakes ( which, long before SOC was discovered, were known as a source of scale-invariant behaviour such as the Gutenberg-Richter law describing the statistical distribution of earthquake sizes, and the Omori law describing the frequency of aftershocks ); solar flares ; fluctuations in economic systems such as financial markets ( references to SOC are common in econophysics ); landscape formation ; forest fires ; landslides ; epidemics ; and biological evolution ( where SOC has been invoked, for example, as the dynamical mechanism behind the theory of " punctuated equilibria " put forward by Niles Eldredge and Stephen Jay Gould ).

This achievement was even more remarkable in light of the series of major earthquakes, landslides, and floods suffered by Ecuador in 1949 and 1950.

Studies of possible local ' mega-tsunamis ' in the Hawaiian Islands draw distinctions between the tsunami wave periods caused by landslides and subduction-zone earthquakes, arguing that a similar collapse in Hawaii would not endanger Asian or North American coastlines.

Turbidites from lakes are also important as they can provide chronologic evidence of the frequency of landslides and the earthquakes that presumably formed them, by dating varves above and below the turbidite.
