valdivia earthquake effects

The eruption initiated itself with a powerful explosive phase, creating a clumn of ash 8 kilometers high from the source. Figure 4[4] is a still from flooding in Quellon, a costal island community several hundred kilometers south of Valdivia. Especially due to somewhat large earthquakes in the 1920s and 1930s, Chilean society still had earthquakes fresh in its mind (Diario Austral, 2010).

The volcano would not erupt again for another 51 years.

The populations of Chile have been adapted to seismic activity for centuries, since the faults lining the Peru-Chile trench are among the most active in the world. [2] Oskin compares the subducting collision of two tectonic plates to rubbing sandpaper together, in that “the crust sticks in some places, storing up energy that is released in earthquakes” (Oskin, 2015). The economic damage totaled $550 million (more than $4.8 billion, adjusted for 2020 inflation). Case Study Boelsche – Valdivia Earthquake 1960, DC Weather Forecast predicts the possible storms, CRED: Centre for Research on the Epidemiology of Disasters, National Geophysical Data Center hazards page, NOAA National Weather Service hazard statistics. Related to the tsumani and the destruction of at least 40% of all structures in the area, flooding ran rampent for several days following May 22. The earthquake hit at 3:11 pm approximately 100 miles (160 km) off the coast of Chile, parallel to the city of Valdivia.The shock is generally agreed to have had a magnitude of 9.5, though some studies alternately proposed that it may have been 9.4 or 9.6. I am now an expert on all things Chilean. Mexico especially sent large amounts of financial aid and donated several schools to the Valdivia area. The Valdivia Earthquake took place on the southern coast of Chile, near the city of Valdivia at 3:11 pm (local time) on May 22, 1960. Most of the problems were structural, since Chile at the time was not nearly as economically affluent as it is today. The second quake would occur slightly over 24 hours later, at 10:30 UTC in the Nahuelbuta National Park, just south of Concepción, reaching 7.1 mw  (USGS, 2016). The immense toll in fatalties and damages was largely due to the secondary effects of the Valdivia earthquake that took place throughout the following days after May 22, inlcuding tsunamies, flooding, lahars, and the even eruption of the Cordón Caulle volcano. I think it was interesting that you included a picture of the flood that was caused by the mass wasting, the reader wouldn’t expect a flood picture to be thrown into an earthquake case study, along with a volcano eruption.

USGS shows the epicenter of the 9.5 mw earthquake situated on the coast just east of Lleulleu Lake, which was actually several hundred kilometers directly north of Valdivia, which appears in Figure 3 (USGS, 2016). When several lahars resulted from the Valdivia earthquake, the Riñihue Lake become completely blocked from a connected outflow river, the San Pedro (Diario Austral, 2010). Add one in the admin panel. In order to engage with the nature of seismology, the reader must have a clear understand of what a subduction zone constitutes. As powerful and destructive that the three Concepción earthquakes were, they would come to alert the rest of the population for what would come. The Force and Effects of the 1960 Valdivia Earthquake.

The 1960 Valdivia earthquake (Spanish: Terremoto de Valdivia) or the Great Chilean earthquake (Gran terremoto de Chile) on 22 May 1960 was the most powerful earthquake ever recorded. I like how you first explain the plates and then introduce the event by starting with the time it started and going from there, it eliminates confusion for the reader and makes your paper sound more scientific.

When the much denser oceanic plate pushes against the less dense continental one, subduction forces the oceanic plate to bend underneath the other, causing the formation of volcanoes, tsunamis and the earth’s largest earthquakes.
