If the application does not load, try our legacy Latest Earthquakes application. The concept of Earthquake Duration Magnitude - originally proposed by E. Bisztricsany in 1958 using surface waves only - is based on the realization that on a recorded earthquake seismogram, the total length of the seismic wavetrain - sometimes referred to as the CODA - reflects its size.Thus larger earthquakes give longer seismograms [as well as stronger seismic waves] than small ones. Record-setting features of the Sumatra-Andaman earthquake of Dec. 26, 2004, include the longest fault rupture ever observed (720 to 780 miles or 1,200 to 1,300 kilometers) and the longest duration . The earthquake lasted between 8 and 10 minutes (one of the longest ever recorded), and lifted the ocean floor several meters, creating a tsunami with 30-meter waves that devastated whole communities. A magnitude 6 earthquake several hundred kilometres away can be often be felt for 30-40 seconds. "Normally, a small earthquake might last less . "Normally, a small earthquake might last less than a second; a moderate sized earthquake might last a few seconds. So the larger the area of the fault that ruptures, the longer the duration of the earthquake. The Sumatran-Andaman earthquake on December 26, 2004, is the longest lasting earthquake ever recorded. Thirty days before and after each group of earthquakes (i.e., T = ±30) was also regarded as the seismic activities period, and the rest of the time was regarded as the non-seismic activities period , as it had the highest identification rate when the duration of seismic activity T = ±30. THE LONGEST recorded earthquake in the history of the world lasted for 32 years and may have killed thousands, according to new research. A magnitude 6 earthquake several hundred kilometres away can be often be felt for 30-40 seconds. Javascript must be enabled to view our earthquake maps.

The major earthquake that struck on the Fairweather Fault had a moment magnitude of 7.8 and a maximum perceived intensity of XI (Extreme) on the Mercalli intensity scale.The epicenter of the quake was at latitude 58.37° N, longitude 136.67° W near the Fairweather Range, 7.5 miles (12.1 km) east of the surface trace of the Fairweather fault, and 13 miles (21 km) southeast of Lituya Bay. According to new information about the earthquake of December 26, 2004, it was the longest-lasting earthquake ever recorded. Most earthquakes will shake for about a second. It was too subtle and gradual to be noticed during its course, but a . Quakes around magnitudes 5-6 often last up to 30 seconds. The aftershocks included the most energetic earthquake swarm ever observed. Unfortunately, there is no fixed time set for how long an earthquake can shake for. In particular, this work is aimed to investigate the recharge system in a carbonate aquifer and to assess its changes caused by a series of strong seismic events. Long-duration earthquakes were defined in this study as those ground motions that have significant duration of a minimum 40 s. The following conclusions can be made: Several cases of rupture of reinforcing bars in RC buildings have been reported after the 2010 Muale earthquake in Chile which were believed to be due to low-cycle fatigue. Latest Earthquakes in the world. Physics of the Earth and Planetary Interiors, 4 (4), 289-300.

In the case of the recent Nepalese earthquake, if the fault movement area was larger, then this potentiallycould have resulted in a larger magnitude, longer duration earthquake. The Sumatra earthquake of 2004 was one of the worst and longest in history. Shaking duration reported between 4 and 10 minutes, devastating Tokyo, Yokohama, Chiba, Kanagawa, and Shizuoka. The moment magnitude of the event was eventually estimated as 9.3, making it one of the largest recorded .

With a magnitude of between 9.1 and 9.3, it is the second largest earthquake ever recorded on a seismograph. Daniel Lao Davila answered on 13 Jun 2014: It seems that the 2004 Sumatra earthquake of magnitude 9.2 had the longest shaking ever recorded for an earthquake. earthquakes today - recent and latest earthquakes, earthquake map and earthquake information. 4,566 earthquakes in the past 30 days. Javascript must be enabled to view our earthquake maps. With a magnitude of 9.1 to 9.3, it lasted at least 10 minutes. The actual duration of slip on the earthquake fault is usually quite brief — just a few seconds for a magnitude 6 for example. A minute before 8 o'clock in the morning local time, a colossal earthquake began to shake the northern part of Sumatra and the Andaman Sea to its north. The first is the length of time it takes for the fault to rupture and the second is the length of time shaking is felt at any given point (e.g. As rightly mentioned by Daniel, the longest recorded earthquake was the 2004 Sumatra earthquake, which shook for about 10 minutes. We would like to show you a description here but the site won't allow us. What is the longest duration of an earthquake? Shaking slid the 93-ton Great Buddha statue at Kamakura almost two feet forward . This earthquake had the longest duration of faulting ever observed, between 8.3 and 10 minutes. It produced a 500-mile-long rupture zone extending from Talca, Chile to the Chiloe Archipelago. The different source models of the Nicaragua earthquake confirm that it had a long duration of 100 to 150 s so that the rupture propagation was slow, of 1.0 to 2.2 km s −1 on average (28, 32, 42, 43). 58,149 earthquakes in the past 365 days. The concept of Earthquake Duration Magnitude - originally proposed by E. Bisztricsany in 1958 using surface waves only - is based on the realization that on a recorded earthquake seismogram, the total length of the seismic wavetrain - sometimes referred to as the CODA - reflects its size.Thus larger earthquakes give longer seismograms [as well as stronger seismic waves] than small ones. This decades-long, silent earthquake—known as a "slow-slip event"—was the longest sequence of its kind ever detected. Now, it seems that tragic event was no isolated incident: It actually marked the end of the longest earthquake ever recorded, which crept through the subsurface for a whopping 32 years. Generally, most earthquakes last only few seconds. There are two ways to think about the duration of an earthquake. Seismological evidence for a lithospheric normal faulting—The Sanriku earthquake of 1933. Record-setting features of the Sumatra-Andaman earthquake of Dec. 26, 2004, include the longest fault rupture ever observed (720 to 780 miles or 1,200 to 1,300 kilometers) and the longest duration of faulting (at least 10 minutes). An earthquake lasted 32 years, and scientists want to know how. Seismological evidence for a lithospheric normal faulting—The Sanriku earthquake of 1933. Seven minutes later a stretch of the Indonesian subduction zone 1200 kilometers long had slipped by an average distance of 15 meters. To access USGS earthquake information without using javascript, use our Magnitude 2.5+ Earthquakes, Past Day ATOM Feed or our other earthquake feeds . According to new information about the earthquake of December 26, 2004, it was the longest-lasting earthquake ever recorded. 1,104 earthquakes in the past 7 days. And larger magnitude earthquakes have larger fault areas. This depends on the size of the earthquake and the observer's distance from it, because earthquake waves spread out as they travel whilst becoming weaker. Numerous large earthquakes have occurred in this area before and after the May 22, 1960 event. This was a megathrust earthquake that occurred at a depth of about 20 miles, where the Nazca Plate is subducting beneath the South American Plate. Various studies have placed it at 9.4-9.6 on the moment magnitude scale.

Dramatic new data from the December 26, 2004, Sumatran-Andaman longest earthquake that generated deadly tsunamis show the event created the longest fault rupture and the longest duration of faulting ever observed, according to three reports by an international group of seismologists published Thursday in the journal "Science." "Normally, a small earthquake might last less than a second . The duration of an earthquake is related to its magnitude but not in a perfectly strict sense. So there is a general relationship between duration and magnitude. The Sumatran-Andaman earthquake, which had a magnitude of 9.1 to 9.3, occurred at the bottom of the Indian Ocean in the subduction zone between the Indo-Australian and . It starts at a point and then the rupture propagates along the fault at around 2 kilometers or so per second.
