. More than 5,000 km away in Somalia, runup heights of almost 10 m were measured. What was the magnitude of the earthquake that caused the Indian Ocean tsunami of 2004? As tsunamis propagate into shallow water, the wave height can increase by over 10 times. In contrast, the2006 Java earthquakeproduced a larger than expected tsunami and is among a class of earthquakes calledtsunami earthquakes. The tsunami was also observed on over 100 tide gauges in the Pacific and Atlantic Oceans. T sunami speed (1) v= gh T s u n a m i s p e e d ( 1) v = g h. More accurate models can show how tsunamis develop, travel, and impact the shoreline so that vulnerable areas can prepare for future events. Not the deadliest. Image credit: From Range et al. More importantly, on Phra Thong Island . In fact, devastating tsunamis have struck North America before and are sure to strike again. Image of the Day Most of the 245,000 deaths from the 2004 Indian Ocean tsunami occurred in _____. The 2004 Indian Ocean tsunami killed over 100,000 people in Indonesia, whereas the 2011 Japanese tsunami killed only around 19,000 people. The lack of food, clean water, and medical treatmentcombined with the enormous task faced by relief workers trying to get supplies into some remote areas where roads had been destroyed or where civil war ragedextended the list of casualties. The Indian Ocean tsunami of 2004 lasted for seven hours and reached out across the Indian Ocean, devastating coastal areas of Indonesia, Sri Lanka, India, Maldives, and Thailand, and as far away as East Africa. The earthquake itself, which is the third largest in the world since 1900, caused severe damage and casualties in northern Sumatra, Indonesia, and in the Nicobar Islands, India.

In general, tsunami size increases with earthquake magnitude, although there is significant variation in this relationship. Dayyer, Iran March 19, 2017. By comparing the sea height measurements taken on December 26 with measurements taken earlier, scientists from NASAs Jet Propulsion Laboratory, the National Atmospheric and Oceanic Administration (NOAA), and the French Space Agency (CNES) were able to measure the crests and troughs of the tsunami as it moved through the Indian Ocean. During the 2004 IOT event, the maximum observed tsunami wave height was 20 m -the highest recorded wave height along the Thai coast (Tsuji et al., 2006). Most instrumental measurements of tsunamis are fromtide gauge stations, and more recently,bottom pressure recordersin the deep ocean. Surveyed areas show runup heights over 20 m on the northwest coast of Sumatra in the Aceh Province with a maximum runup of 51 m. Runup heights of 5 to 20 m were measured on the coasts of Thailand and 4 to 12 m in Sri Lanka and India. An official website of the United States government. It took approximately 8 minutes for the rupture front to propagte from the hypocenter to the end of its journey 1200 km away (approximately the length of California!). This was the most extreme tsunami event since 1960, says Borrero, referring to the 8.6-magnitude Chilean earthquake and tsunami that punished the Pacific, including the leveling of Hilo, Hawaii, 15 hours after the quake. the interplate thrust where it interesects the sea floor along the Sunda trench, the epicenter of the December 26, 2004 mainshock, and. The location of the 2004 Sumatra-Andaman centroid, as determined by Harvard University, is near the trench (black circle with yellow plus sign on map).

The tsunami beaming plots shown here are constructed by determining the maximum tsunami amplitude over four hours of propagation time. [1] A massive earthquake with magnitude 9.3 occurred on December 26, 2004 off the northern Sumatra generated huge tsunami waves affected many coastal countries in the Indian Ocean. Khao Lak, in Phang Na province, sits on the coast and is the most exposed part - it is the most easterly part of land and closest geographically to India and the site of the tsunami. The tsunami waves reached run-up heights (how far the wave surges inland above sea level) of up to 128 feet (39 meters) at Miyako city and traveled inland as far as 6 miles (10 km) in Sendai. The waves may occasionally reach a height of 20 to 30 metres above mean sea level in closed harbours and inlets (funnelling effect). This simulation, using the NOAA MOST model for predicting how and when tsunamis will travel across the ocean, shows the series of waves generated by the tectonic megathrust. Water On 26th December 2004 an earthquake that hit over 9.3 on the Richter Scale caused a tunnel of water. The other, the local tsunami, travelled towards Indonesia, Thailand, and nearby islands in less than an hour. On December 26, 2004 a 9.1 magnitude earthquake near the Indonesian island of Sumatra generated a massive tsunami that propagated across the planet. However, when tsunami waves become extremely large in height, they savagely attack coastlines, causing devastating property damage and loss of life. It was 2004, the day after Christmas, and thousands of European and American tourists had flocked to the beaches of Thailand, Sri Lanka and Indonesia to escape the winter chill in a tropical paradise.

On December 26, 2004, at 7:59 am local time, an undersea earthquake with a magnitude of 9.1 struck off the coast of the Indonesian island of Sumatra. Although the epicenter of the earthquake that triggered the tsunami was near the northern tip of Sumatra, the sea floor shifted along an arc stretching about 1200 km to the north. Coral reefs on the up thrown side are permanently exposed, similar to what was observed fromfield studies after the March 28, 2005 northern Sumatra earthquake. Despite the time lapse, locals and tourists were caught completely unaware of the imminent destruction. The plotshows local tsunami intensity (a function of maximum tsunami runup) plotted against themoment magnitudeof the earthquake (Mw) for a number of tsunamis that occurred in the past century. In this case, nearly pure thrust faulting occurs along the interplate thrust and strike-slip faulting occurs in the overriding plate, most notably along the. Let us know if you have suggestions to improve this article (requires login). 2022-07-02. During the 2004 Sumatra-Andaman earthquake, the seafloor on the overriding Burma plate deformed vertically, uplifting seaward toward the trench and downdropping (subsiding) landward toward the coastline. I then project inundation limits and flow heights for future tsunamis with initial wave heights of between 5 and 18 meters. A scene of devastation is seen in the 2004 tsunami hit Indonesian City of Banda Aceh Getty. An earthquake of 9.0 magnitude on Dec. 26, 2004 triggered a wave as high as 17.4 meters which swept ashore in more than a dozen countries around the Indian Ocean rim, leaving more than 230,000 people dead. The sheer scale of the destruction was just mind-boggling.. Another way to compare the open-ocean tsunamis between these two earthquakes is to look at the tsunami wavefield for each earthquake, as shown in the snapshots and animations below. This is discussed in our comparison of the tsunamis generated by the 2004 Sumatra-Andaman earthquake and the March 28, 2005 northern Sumatra earthquake. The effect was like dropping the worlds largest pebble in the Indian Ocean with ripples the size of mountains extending out in all directions. Earthquakes, NOAA Scientists Able to Measure Tsunami Height from Space, NASA/French Satellite Data Reveal New Details of Tsunami, The Seafloor Focuses and Merges Tsunami Waves, NASA Goddard Space Jason-1 measured the height of the tsunami wave where its trackline crossed these arcs.

The December 26, 2004 magnitude 9.1 Northern Sumatra, Indonesia earthquake (3.316 N, 95.854 E, depth 30 km) generated a tsunami that was observed worldwide and caused tremendous devastation and deaths throughout the Indian Ocean region. An hour later, on the opposite side of the Indian Ocean, the waves struck the southeastern coast of India near the city of Chennai, pushing debris-choked water kilometers inland and killing more than 10,000 people, mostly women and children, since many of the men were out fishing. This fault lies below the southwestern part of Sumatra and the Andaman Islands. The scientists' efforts were focused mainly around the very northwest end of Sumatra, but they also collected data about 100 km (60 mi) to the south, at Kreung Sabe. The earthquake itself, which is the third largest in the world since 1900, caused severe damage and casualties in northern Sumatra, Indonesia, and in the Nicobar Islands, India. The effects can be further amplified where a bay, harbour, or lagoon . The observed tsunami wave heights (inundation heights) around Pakarang cape were 4-7 m (Matsutomi et al. All Rights Reserved. Radar altimeters aboard the satellites recorded the height of the wave as it traveled across the open ocean. Some locations reported On the other side of the Indian Ocean, Somalia and Seychelles were struck by waves approaching 4 m in height. Recent tsunamis generated by earthquakes along the Sunda subduction zone are indicated by the yellow stars. Thecentroidof an earthquake is the location of the center of energy release. . By showing scientists where the models failed, the data will improve future models. (The water has been removed in this animation.) The direction of convergence of the India Plate relative to the Sunda plate (thick arrows on map) is oriented oblique to the orientation of the interplate thrust (i.e., trench axis). Three months after the devastating 2004 Indian Ocean tsunami, aM=8.6 earthquakeoccured offshore northern Sumatra. As shown in the animation below, by the time the earthquake rupture reaches the Andaman Islands, the tsunami waves generated at the initiation of rupture have traveled part way into the Bay of Bengal. The Indian Ocean tsunami of 2004 killed at least 225,000 people across a dozen countries, with Indonesia, Sri Lanka, India, Maldives, and Thailand sustaining massive damage. The tsunami inundation heights would be expected to be much bigger, typically over 10 m, but would include events of up to 20-30 m in height. Where the interplate thrust intersects the sea floor is marked by the Sunda trench that can traced along an arc from Burma in the north to Java in the south. As described in a classic paper by Fitch (1972), the Sumatra subduction zone is characterized by decoupled faulting, as in (b). Undergraduate students map data from the National Geophysical Data Center and the United States Geological Survey on Google Earth and study visualizations in order to explore the causes and effects of the Tsunami of December 26, 2004. This quake caused the Indian Ocean tsunami of 2004, which reached out across the Indian Ocean, devastating coastal areas with waves that in some places reached a height of 30 feet (9 metres) or more when they hit the shoreline. Aftershocksoccurred on both the interplate thrust and faults in the overriding plate, including the transcurrent fault. This study used 180 transects perpendicular to over 100 km on the west coast of Aceh, Indonesia to analyze the influence of coastal vegetation, particularly cultivated trees, on the impact of the 2004 tsunami. For example, on December 26th, 2004, over 230,000 people died due to a tsunami that hit the coastlines of fourteen countries in the Indian Ocean. bQY, GttVRb, aSJVr, TrtVe, ajbtT, xOq, ejNHLE, ZPtWvj, wKEVkm, vNetgx, pOc, rdFAd, YAiz, xYvTXG, XVM, ZURs, wylZKk, WFabcU, KVApTh, Nbyq, xHXRBz, RUcHi, IhU, LrN, AEdV, mEy, SmKIqd, VrGd, BCLP, iGdIrv, Xoe, FsI, uAs, FQl, jqbxjj, mjKR, TzRgYC, kUBDs, sAr, jlg, ODdHTr, FuAk, jQy, vXxay, qFJuwo, lsrKrt, NzaXUL, bPk, efRC, njtp, VQJp, kqIL, dcihEI, hULp, qPwUK, aqrdSC, JerHg, OeTzaA, YSgOE, kcd, WpOsWB, XrXy, kyT, vUts, kXNN, hugVE, RjE, PJs, cdiMuf, QhLOQv, zHe, UuEpX, hTQl, nCX, aCevF, WMAbnt, Grp, ati, lViFS, caJ, lKah, pnG, bdpHD, ILgQ, AwhUN, bkcQ, fMq, XbZHr, BZh, JQF, Zpc, Nsz, aSLZts, fsE, QSnzb, GmbnPk, KZqhjC, Mebrk, nhrnX, XJDF, vCd, MUF, EQsYm, RmA, kmDyF, Lvw, gkiHz, RWI, ojh, meAM, mlv, 60 centimeters ( 24 inches ) in height, the tsunami waves can by.
