The Richter scale [1] (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale".

[14] [15] [16] It was considered the worst earthquake to affect Pakistan since the 2005 Kashmir earthquake. Many survivors suffered broken bones or lost a limb when the buildings they were inside collapsed. [17] The earthquake affected a sparsely populated region of southern Pakistan where most of the population live in poverty.
Local date: 11 January 1693 (): Local time: 21:00 [1] [2]: Duration: 4 minutes: Magnitude: 7.4 M w: Epicenter: 3] The exact location of the epicentre remains uncertain: Areas affected: Southern Italy, notably Sicily, and Malta [4]: Max. intensity: MMI XI (Extreme) [5]: Tsunami: 5–10-metre high waves devastated the coastal villages on the Ionian Sea and in the Straits of Messina. (Ambraseys ...
The earthquake caused $7 billion in damage. [56] Direct economic loss represented 0.24 of the nation's GDP, or $308 million. [57] Some homes in older parts of Marrakesh and portions of the city walls collapsed, [58] leaving families trapped beneath debris. [59]
ECDM map. The earthquake occurred as a result of oblique reverse and strike-slip faulting.The rupture had an area of 51 km (32 mi) × 28 km (17 mi), and occurred on either a moderately dipping oblique reverse and right-lateral fault striking east, or a steeply dipping oblique reverse and left-lateral fault striking west.

The swarm began in December 2020 at depths greater than 15 km (9.3 mi) beneath the peninsula's northeast. By mid-March 2021, the earthquake swarm migrated to shallower depths above 15 km (9.3 mi). Most earthquakes after May 2021 occurred at 10–15 km (6.2–9.3 mi) depth. The M w 7.5 earthquake occurring after the swarm was deemed "rare". The ...
An earthquake struck west of Paphos, Cyprus on 11 January 2022, with a moment magnitude of 6.6. [3] The earthquake was the largest tremor to occur in the Mediterranean Sea since the 2003 Boumerdès earthquake, [4] and the largest to occur in Cyprus since 1996. [5]
The China Earthquake Networks Center said the seismic sequence was consistent with a mainshock–aftershock type event. Within 200 km (120 mi) of the earthquake's epicenter, only three earthquakes greater than magnitude 6.0 have occurred. [16] In 1936, a M s 6.8 earthquake caused significant destruction and deaths in Kangle County, Gansu. [17]
