Note: The inclusion criteria for adding events are based on WikiProject Earthquakes' notability guideline that was developed for stand-alone articles. The principles described also apply to lists. In summary, only damaging, injurious, or deadly events should be recorded.
The 1977 Tonga earthquake took place on 23 June at 01:08:33 local time some 200 km southwest of Tongatapu, with shocks affecting all islands of the kingdom of Tonga. The earthquake measured 8.0 on the moment magnitude scale and had a maximum intensity of VIII (Severe) on the Mercalli intensity scale. The earthquake caused considerable damage to ...
The American wharf in Nukuʻalofa sustained cracks in addition to those caused by the 1977 earthquake. A ship, sunk in 1949 near Toula, Vavaʻu apparently burst open and its load of copra came floating to the ocean surface. A landslide occurred at Hunga island in Vavaʻu, when the ground at a steep cliff along the shore began sliding into the sea.
Several events caused significant numbers of fatalities especially in Iran which had 3 earthquakes throughout the year with a combined death toll of around 1,120 people. The deadliest earthquake occurred in Romania in March and was the worst in the country's history. 1,641 people were killed in this event.
The earthquake was at a depth of 24.8 km (15.4 miles) that struck the sea at about 211 km (131 miles) east of south-east of Neiafu, according to the United States Geological Survey (USGS). "Based ...
A pie chart comparing the seismic moment release of the three largest earthquakes for the hundred-year period from 1906 to 2005 with that for all earthquakes of magnitudes <6, 6 to 7, 7 to 8, and >8 for the same period. The 2011 Japan quake would be roughly similar to Sumatra. Earthquakes of magnitude 8.0 and greater from 1900 to 2018.
Historical earthquakes is a list of significant earthquakes known to have occurred prior to the early 20th century. As the events listed here occurred before routine instrumental recordings — later followed by seismotomography imaging technique, [1] observations using space satellites from outer space, [2] artificial intelligence (AI)-based earthquake warning systems [3] — they rely mainly ...
In December 2014 and January 2015, a volcanic island 1 km wide by 2 km long was created adjacent to the island of Hunga Tonga–Hunga Ha'apai 65 kilometers northwest of Nuku'alofa. The volcanic eruption has built the new island to a height of 100 m composed of ash and large rock fragments. [4]
