In 25 localities, where more diagnostic environmental effects occurred, we have applied the ESI 2007 scale (Guerrieri & Vittori 2007) in order to evaluate the intensity: in the Straits area the ESI values are one or two degrees lower than the MCS values (the maximum ESI value is X, while the maximum MCS value is XI). The approach is here applied to compute the coseismic displacements along selected 2-D cross sections intersecting the Messina Straits (southern Italy), where one of the most catastrophic tsunamis hitting the Italian coasts was generated by the December 28, 1908, M=7.2 earthquake. Effects of the 1908 earthquake.

And they can be made resistant to earthquake vibrations. Most of our building codes are designed to protect first the building occupants, and second the building integrity. Messina earthquake and tsunami of 1908. In southern Italy in 1909 more than 100,000 people perished in an earthquake that struck the region. In the 1811-12 earthquakes the sand blows were enormous and covered large regions of the Missouri bootheel.

On June 25, 1896 an earthquake off the Japanese coast generated a tsunami that hit the shore with wave heights ranging from 10 to 100 feet. Messina and Reggio Calabria were almost totally destroyed. We have to consider that the ESI scale is calibrated on the MM and MSK scales, which provide intensity estimates lower than the MCS scale for the highest degrees.

Few minutes after the earthquake, both sides of the Straits were inundated by several tsunami waves, worsening the ruinous effects due directly to the earthquake.

The double catastrophe almost completely destroyed Messina, Reggio di Calabria, and dozens of nearby coastal towns. At 7 AM, as survivors from a nearby station (located higher up the cliff but considerably damaged and evacuated when the waves hit) were searching for survivors, the tsunami arrived 2200 km at Hawaii away where a series of waves struck the islands killing 159 more people.

Use, Smithsonian Portions of the coast were lost, especially on the Calabrian side, most of them because of landslides and the combined action of the tsunami erosion and the earthquake shaking (at Lazzàro the shoreline retreated landward 175 m; Novarese, 1909). In 1992-93 three large tsunamis occurred: one in Japan, Indonesia, and Nicaragua. These waves are typically more devastating to the coastal region than the shaking of the earthquake that caused the tsunami. We need different levels of resistance for different classes of structures. Often unstable regions of hillsides or mountains fail. When a tsunami approaches the shore, the water depth decreases, the front of the wave slows down, the wave grows dramatically, and surges on land. The generation mechanism of earthquake-induced tsunamis is generally assumed to be related to the sudden displacement of the seafloor induced by the seismic shock. This goal can be accomplished by means of a hybrid approach we developed recently, which solves the equilibrium equations of linear elasticity in two dimensions through both the analytical FFS solutions and a finite element code. 80 slope movements occurred in many Sicilian and Calabrian localities (especially between Reggio Calabria and Bagnara) mainly along coastal areas, but also inland.

Tsunamis pose no threat in the deep ocean because they are only a meter or so high in deep water. In 1883 the volcanic eruption of Krakatoa resulted in the collapse of a caldera that initiated a tsunami which killed 36,000 people on nearby islands. Occasionally large landslides can be triggered by earthquakes. The same material would eventually fail with increased time, but earthquakes trigger many slides that do much bit of damage. The aftereffects of the earthquake were well-documented both in the United States and Italy. Okada, 1992).

The double catastrophe almost completely destroyed Messina, Reggio di Calabria, and dozens of nearby coastal towns. At 7 AM, as survivors from a nearby station (located higher up the cliff but considerably damaged and evacuated when the waves hit) were searching for survivors, the tsunami arrived 2200 km at Hawaii away where a series of waves struck the islands killing 159 more people.

Use, Smithsonian Portions of the coast were lost, especially on the Calabrian side, most of them because of landslides and the combined action of the tsunami erosion and the earthquake shaking (at Lazzàro the shoreline retreated landward 175 m; Novarese, 1909). In 1992-93 three large tsunamis occurred: one in Japan, Indonesia, and Nicaragua. These waves are typically more devastating to the coastal region than the shaking of the earthquake that caused the tsunami. We need different levels of resistance for different classes of structures. Often unstable regions of hillsides or mountains fail. When a tsunami approaches the shore, the water depth decreases, the front of the wave slows down, the wave grows dramatically, and surges on land. The generation mechanism of earthquake-induced tsunamis is generally assumed to be related to the sudden displacement of the seafloor induced by the seismic shock. This goal can be accomplished by means of a hybrid approach we developed recently, which solves the equilibrium equations of linear elasticity in two dimensions through both the analytical FFS solutions and a finite element code. 80 slope movements occurred in many Sicilian and Calabrian localities (especially between Reggio Calabria and Bagnara) mainly along coastal areas, but also inland. A very nice site with a description of historical and recent tsunamis events. Agreement NNX16AC86A, EGU General Assembly Conference Abstracts, Is ADS down? According to Michelini et al. Tsunamis pose no threat in the deep ocean because they are only a meter or so high in deep water. In 1883 the volcanic eruption of Krakatoa resulted in the collapse of a caldera that initiated a tsunami which killed 36,000 people on nearby islands. Occasionally large landslides can be triggered by earthquakes. The same material would eventually fail with increased time, but earthquakes trigger many slides that do much bit of damage. The aftereffects of the earthquake were well-documented both in the United States and Italy. Okada, 1992). Also descriptions of gas emissions have been collected as well as a number of testimonies of rumbles and lights. Tsunami information is readily available on the world-wide-web, here are some links to check out: A nice site with photos, articles, and links to other tsunami sites. Thus Macelwane Hall resonates at about 0.3 seconds period, and Griesedeck at about 1.4 seconds. Change ), You are commenting using your Facebook account. The analysis of the contemporary sources allowed us to reconstruct a representative distribution of ground coseismic environmental effects of the 1908 earthquake, which was not available so far. Moreover, the strong earthquakes that struck this area in 1894, 1905 and 1907 had certainly weakened the buildings, many of them constructed using fluvial stones and poor quality mortar, which had been badly restored afterwards. Change ), You are commenting using your Google account. (or is it just me...), Smithsonian Privacy Fortunately many tall buildings are constructed to withstand strong winds and some precautions have been taken to reduce their tendency to shake.

Moments after the earthquake, a 12-meter (39-foot) tsunami struck nearby coasts, causing even more devastation; 91% of structures in Messina were destroyed and some 70,000 … This is a very interesting "log" of a deadly 1946 tsunami.

The damages were particularly catastrophic along the Calabrian … The earthquake was followed by tidal waves and fires and left many people homeless.

technical and photographic reports, newspapers and other archive material. together and have the entire structure behave as a single stiff unit that moves with the ground, or you construct a strong and flexible structure that distorts but doesn't break and absorbs some of the shaking energy.
