Introduction In this paper, three case-histories of bridges investigated by the Geotechnical Extreme Events Reconnaissance (GEER) teams during several visits after the 2010 M8.8 Maule earthquake are presented. The region is prone to earthquakes, and in 2010 a magnitude-8.8 earthquake caused widespread damage in Maule (see Chile earthquake of 2010). No damage was observed by the first author. Maule Earthquake On February 27, 2010 a magnitude 8.8 earthquake struck Maule, Chile causing widespread damage and casualties. According to government statistics, 370,000 dwellings had severe damage (MINVU, 2010). The MSK-64 seismic intensities inside the damage area of the 2010 Maule earthquake are estimated. With this purpose, field surveys of damage to typical The massive shockwaves and accompanying tsunami of the 2010 Maule, Chile, earthquake (magnitude 8.8) killed more than 300 people, affected nearly 2 million others, and damaged or destroyed approximately half a million homes, schools, hospitals and other buildings . At least 521 people were killed, 56 missing, about 12,000 injured, 800,000 displaced and at least 370,000 houses, 4,013 schools, and 79 hospitals damaged or destroyed by the earthquake and tsunami. 1. 2. On February 27, 2010 a magnitude 8.8 earthquake struck Maule, Chile causing widespread damage and casualties. Extensive bridge damage was reported after the 2010 Maule earthquake in Chile due to inadequate seismic design. The tsunami associated with the 1906 earthquake produced some damage in Hawaii, with reported run-up heights as great as 3.5 m. Approximately 870 km to the north of the February 27 earthquake is the source region of the magnitude 8.5 earthquake of November, 1922. earthquake in the Maule region of Chile caused severe damage to buildings which were designed based on the Chilean codes. On June 22, 2021, Peru experienced an earthquake of magnitude 6.0 on the Richter scale. To understand the implications of the observed failures in Maule construction for in the United States, it was essential to undertake a methodical study of the buildings that failed and An earthquake measuring 8.8 on the Richter scale occurred in the Maule region of Chile. A small tsunami was reported. By Raul Madariaga. Maule region The Maule region, which includes the cities of Constitución and Talca, was the area most affected by the earthquake, with more than 580 deaths. Short-Period Rupture Process of the 2010 M w 8.8 Maule Earthquake in Chile. As was brought up earlier, the M=5.9 quake yesterday occurred near the rupture zone of the 2010 M=8.8 Maule earthquake, which killed 525 people and resulted in billions of dollars worth of damage.

Damage Assessment and Seismic Intensity Analysis of the 2010 (Mw 8.8) Maule Earthquake - Maximiliano Astroza, Sergio Ruiz, Rodrigo Astroza, 2012 For each tsunamigenic earthquake in the catalog, the models capture the entire lifespan of the resulting tsunami—from 983,400; (2017) 1,044,950. Five levels of damage are depicted in the map, with level 5 being the worst: level 5 (red), level 4 (orange), level 3 (yellow), level 2 (green), and level 1 (white). This may explain the small number of slope failures caused by the earthquake. The magnitude of the earthquake is estimated as Mw 8.8. in comparison to the other earthquake-hit countries. South of Concepción, the source of the 2010 earthquake adjoins a fault rupture nearly 1,000 km long that produced the largest 20th-century earthquake worldwide, the giant … In earthquake-prone regions such as Chile,(re)insurers need more sophisticated tools to quantify the risks facing their businesses, including models with the ability to estimate secondary losses. 2. Constitución, which was also struck by waves from the tsunami, suffered some of the heaviest damage. The agency is reporting a depth of 30.9 km (19.2 miles). Damage observed after the 2010 Maule Earthquake. We believe thatthe mainresponsible ofthese variationsarethe surface Many people were also seriously injured. 225 people killed. The earthquake caused damage to high- There was no observed or - reported damage in any of the seven subterranean levels. 9. LESSONS LEARNED FROM THE EARTHQUAKE ... Table 7 summarizes the characteristics and earthquake-induced damage patterns of bridges with a skew angle of 20 degrees or more. I saw a healthy mixture of truth and falsehood in the answers, and considerable confusion in the question.
