The magnitude 5.7 Little Skull Mountain (LSM) earthquake the following day, June 29, 1992, at 10:14 UTC near Yucca Mountain, Nevada, is also considered part of the regional sequence and may have been triggered by surface wave energy produced by the Landers earthquake. Foreshock activity, in the form of a significant increase in micro ...
The epicenter region of the earthquake was located in the San Fernando Valley, about 30 km (19 mi) northwest of downtown Los Angeles. The United States Geological Survey (USGS) placed the hypocenter 's geographical coordinates at 34°12′47″N 118°32′13″W / 34.213°N 118.537°W / 34.213; -118.537 and at a depth of 11.31 miles ...
In the Himalayan region, where the Indian plate subducts under the Eurasian plate, the largest recorded earthquake was the 1950 Assam–Tibet earthquake, at magnitude 8.7. It is estimated that earthquakes with magnitude 9.0 or larger are expected to occur at an interval of every 800 years, with the highest boundary being a magnitude 10, though ...
Map of earthquakes in 2011. This is a list of earthquakes in 2011. Only earthquakes of magnitude 6 or above are included, unless they result in damage and/or casualties, or are notable for some other reason. Smaller events in remote areas will be excluded from the list as they wouldn't have generated significant media interest.
A seismogram recorded in Massachusetts, United States. The magnitude 9.1 (M w) undersea megathrust earthquake occurred on 11 March 2011 at 14:46 JST (05:46 UTC) in the north-western Pacific Ocean at a relatively shallow depth of 32 km (20 mi), [9] [56] with its epicenter approximately 72 km (45 mi) east of the Oshika Peninsula of Tōhoku, Japan, lasting approximately six minutes.
1979 Imperial Valley earthquake – magnitude 6.4 earthquake with an epicenter less than 1 km inside Mexico – significant damage and injuries on both sides of the border (60 in the US) 2010 Baja California earthquake (Mexico near S California) – magnitude 7.2 earthquake, 4 fatalities and 100 injuries, none in the United States
If the eastern portion of the megathrust did rupture, then a magnitude of M w 9.0–9.1 is more reflective of the event. [17] The tsunami created by the earthquake suggests a (M t 9.0) event. [4] The earthquake was previously assigned magnitude 9.1 and subsequent analysis have revised it to magnitude 8.6. [21]
The list incorporates high-quality earthquake source (i.e., origin time, location and earthquake magnitude) and fatality information from several sources. Earthquake locations are taken from the Centennial Catalog [ 1 ] and the updated Engdahl, van der Hilst and Buland earthquake catalog, [ 2 ] which is complete to December 2005.
