Mercalli Intensity Scale
The Modified Mercalli intensity scale (MM, MMI, or MCS), developed from Giuseppe Mercalli's Mercalli intensity scale of 1902, is a seismic intensity scale used for measuring the intensity of shaking produced by an earthquake. It measures the effects of an earthquake at a given location, distinguished from the earthquake's inherent force or strength as measured by seismic magnitude scales (such as the "" magnitude usually reported for an earthquake). While shaking is caused by the seismic energy released by an earthquake, earthquakes differ in how much of their energy is radiated as seismic waves. Deeper earthquakes also have less interaction with the surface, and their energy is spread out across a larger volume. Shaking intensity is localized, generally diminishing with distance from the earthquake's epicenter, but can be amplified in sedimentary basins and certain kinds of unconsolidated soils. Intensity scales empirically categorize the intensity of shaking based on the effect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2018 Hawaii Earthquake
On May 4, 2018, an earthquake with a magnitude of 6.9 struck Hawaii island in the Hawaii archipelago at around 12:33 p.m. local time. The earthquake's epicenter was near the south flank of Kīlauea, which has been the site of seismic and volcanic activity since late April of that year. According to the United States Geological Survey the quake was related to the new lava outbreaks at the volcano, and it resulted in the Hilina Slump moving about two feet. It was the largest earthquake to affect Hawaii since the 1975 earthquake, which affected the same region, killing two people and injuring another 28. The earthquake had a maximum strength on the Mercalli intensity scale of VIII (''Severe''). The earthquake was preceded by a smaller event, measuring 5.4, that was felt across the island and as far away as Oahu. The earthquake produced a minor tsunami that reached a maximum height of 40 cm (15.7 in.) in Kapoho, 20 cm (7.9 in.) in Hilo and 15 cm (5.9 in.) in ...

2006 Kiholo Bay Earthquake
The 2006 Kīholo Bay earthquake occurred on October 15 at with a magnitude of 6.7 and a maximum Mercalli intensity of VIII (''Severe''). The shock was centered southwest of Puakō and north of Kailua-Kona, Hawaii, just offshore of the Kona Airport, at a depth of . It produced several aftershocks, including one that measured a magnitude of 6.1 seven minutes after the main shock. The Pacific Tsunami Warning Center measured a nondestructive tsunami of on the coast of the Big Island. Tectonic setting The island of Hawaii is affected by earthquakes related to three main causes. Some are associated with the movement of magma and tend to be shallow focus (less than depth). The largest earthquakes are those caused by overall gravitational spreading of the volcano, whether within the volcano's flanks or at the base of the volcanic pile. They tend to have focal depths in the range . The final group of earthquakes are those caused by flexure of the oceanic lithosphere underlyin ...

1983 Kaoiki Earthquake
The 1983 Kaoiki earthquake struck southern Hawaii Island on the morning of November 16, 1983. Measuring 6.7, it was the largest to hit the island since 1975. The epicenter was located 50 km (30 mi) southeast of Hilo with an approximated depth of 12 km (7 mi). The shallow strike-slip earthquake was assigned a maximum intensity of IX (''Violent'') on the Modified Mercalli scale. 6 people were injured, widespread damage and landslides were reported across the island. Tectonic setting The epicenter in Kaoiki lies within a valley between the western slope of Mauna Loa, and northwest of Kīlauea. Seismicity in the area is caused by the continuous movement of the Kilauea and Mauna Loa slumps generated by the continuous magmatic flow underground. This strain forms the many faults around the Kilauea block and the notable Hilina Slump. The slump is situated underwater—below the southern flanks of Kilauea. As the block continues to stretch at around 10 cm/year s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

1975 Hawaii Earthquake
The 1975 Hawaii earthquake occurred on November 29 with a moment magnitude of 7.7 and a maximum Mercalli intensity of VIII (''Severe''). The shock affected several of the Hawaiian Islands and resulted in the deaths of two people and up to 28 injured. Significant damage occurred in the southern part of the Big Island totalling $4–4.1 million, and it also triggered a small brief eruption of Kilauea volcano. The event generated a large tsunami that was as high as on Hawaii'i island and was detected in Alaska, California, Japan, Okinawa, Samoa, and on Johnston and Wake Islands. Significant changes to the shorelines along the southern coast of the Big Island with subsidence of was observed, causing some areas to be permanently submerged. The source of the event was the Hilina Slump, which was also responsible for the more powerful 1868 Hawaii earthquake and tsunami.

1868 Hawaii Earthquake
The 1868 Hawaii earthquake was the largest recorded in the history of Hawaii island, with an estimated magnitude of 7.9 and a maximum Mercalli intensity of X (''Extreme''). The earthquake occurred at 4 p.m. local time on April 2, 1868 and caused a landslide and tsunami that led to 77 deaths. The aftershock sequence for this event has continued up to the present day. Background The island of Hawaii (commonly called the "Big Island") is the currently active volcanic center of the Hawaiian Islands formed over the Hawaii hotspot. Two of the active volcanoes on the Big Island are Kīlauea and Mauna Loa with a newer submarine volcano forming the Kamaʻehuakanaloa Seamount (formerly Loihi) to the southeast of the island. Continued growth of the southeastern part of the island is accompanied by major slumping and southeastward movement of the flanks of the two volcanoes. This flank displacement is linked to extension within the rift zones associated with both of the active volcanoes, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Earthquakes
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For ex ...
