The shallow fault was about 32 kilometres (20 mi) long around the western side of the town of Meckering. It damaged roads including the Great Eastern Highway, the Eastern Goldfields Railway and the Goldfields water pipeline. It formed a fault scarp up to 1.5 metres (5 ft) high with overthrusting to the west of up to 2 metres (7 ft) and strike-slip displacement of up to 0.9 metres (3 ft). [4]

The effect of the earthquake involved structures in Perth, [6] the capital of Western Australia 130 km west of Meckering. It occurred mid-morning of a public holiday, the Queen's Birthday and theatres were packed with children. [7]

1999 Düzce earthquake

The 1999 Düzce earthquake occurred on 12 November at 18:57:22 local time with a moment magnitude of 7.2 and a maximum Mercalli intensity of IX (Violent), causing damage and at least 845 fatalities in Düzce, Turkey. The epicenter was approximately 100 km (62 mi) to the east of the extremely destructive 1999 İzmit earthquake that happened a few months earlier. Both strike-slip earthquakes were caused by movement on the North Anatolian Fault.

1999 Hector Mine earthquake Magnitude 7.1 earthquake in California

The 1999 Hector Mine earthquake occurred on October 16 at 02:46:50 PDT with a moment magnitude of 7.1 and a maximum Mercalli intensity of VII. The strike-slip earthquake occurred in a remote part of the Mojave Desert, 47 miles (76 km) east-southeast of Barstow, California, inside the Twentynine Palms Marine Corps Base. Its name comes from a nearby quarry named Hector Mine, which is located 22 kilometers (14 mi) northwest of the epicenter. Strike-slip faults are fractures where the blocks have mostly moved horizontally. If the block opposite of an observer looking across the fault moves to the right, the slip style is termed right lateral; if the block moves to the left, the motion is termed left lateral.

1939 Erzincan earthquake Earthquake in Turkey in 1939

The 1939 Erzincan earthquake struck eastern Turkey at 1:57:23 a.m. on 27 December local time with a moment magnitude of 7.8Mw and a maximum Mercalli intensity of XII (Extreme). It was the second most powerful earthquake recorded in Turkey, after the 1668 North Anatolia earthquake. This was one of the largest in a sequence of violent shocks to affect Turkey along the North Anatolian Fault between 1939 and 1999. Surface rupturing, with an horizontal displacement of up to 3.7 meters, occurred in a 360 km long segment of the North Anatolian Fault Zone. The earthquake was the most severe natural loss of life in Turkey in the 20th century, with 32,968 dead, and some 100,000 injured.

1946 Vancouver Island earthquake Canadian natural disaster

The 1946 Vancouver Island earthquake struck Vancouver Island on the coast of British Columbia, Canada, on June 23 at 10:15 a.m. with a magnitude estimated at 7.0 Ms and 7.5 Mw. The main shock epicenter occurred in the Forbidden Plateau area northwest of Courtenay. While most of the large earthquakes in the Vancouver area occur at tectonic plate boundaries, the 1946 Vancouver Island earthquake was a crustal event. Shaking was felt from Portland, Oregon, to Prince Rupert, British Columbia. This is one of the most damaging earthquakes in the history of British Columbia, but damage was restricted because there were no heavily populated areas near the epicentre, where severe shaking occurred.

1915 Pleasant Valley earthquake

The 1915 Pleasant Valley earthquake occurred at 22:53:21 on October 2 in north-central Nevada. With a moment magnitude of 6.8 and a maximum Mercalli intensity of X (Extreme), it was the strongest earthquake ever recorded in the state.

1991 Uttarkashi earthquake October 1991 earthquake in Uttarkashi, India

The 1991 Uttarkashi earthquake occurred at 02:53:16 20 October local time with a moment magnitude of 6.8 and a maximum Mercalli intensity of IX (Violent). This thrust event was instrumentally recorded and occurred along the Main Central Thrust in the Uttarkashi and Gharwal regions of the Indian state of Uttarakhand. High intensity shaking resulted in the deaths of at least 768 people and the destruction of thousands of homes.

1980 El Asnam earthquake 1980 earthquake on the Algerian coast

The 1980 El Asnam earthquake occurred on October 10 at 13:25:23 local time with a moment magnitude of 7.1 and a maximum Mercalli intensity of X (Extreme). The shock occurred in the Algerian town of El Asnam. The shocks were felt over 550 km (340 mi) away, with the initial earthquake lasting 35 seconds. It was the largest earthquake in Algeria, and was followed three hours later by a magnitude 6.2 aftershock. The earthquake created about 42 km (26 mi) of surface rupture and had a vertical slip of up to 4.2 m (14 ft). No foreshocks were recorded. The earthquake was found to have occurred very close to the epicenter of the 1954 Chlef earthquake using joint epicenter determination techniques. It occurred at a previously unknown reverse fault.

Earthquakes have occurred in Western Australia (WA) on a regular basis throughout its geological history.

1984 San Pedro Basin earthquake

The 1984 San Pedro Basin earthquake occurred on June 24 at 07:17:14 local time with a moment magnitude of 6.7 and a maximum Mercalli intensity of VII. The event occurred off the southern coast of the Dominican Republic and resulted in an estimated five fatalities.

1967 Mudurnu earthquake Earthquake in western Turkey

The 1967 Mudurnu earthquake or more correctly, the 1967 Mudurnu Valley earthquake occurred at about 18:57 local time on 22 July near Mudurnu, Bolu Province, north-western Turkey. The magnitude 7.4 Mw earthquake was one of a series of major and intermediate quakes that have occurred in modern times along the North Anatolian Fault since 1939.

1994 Java earthquake

The 1994 Java earthquake occurred on June 3 at 01:17:37 local time on June 2, at 18:17:37 GMT off the coast of Indonesia. The epicenter was off the eastern part of the southern Java coast, near the east end of the Java Trench.

1931 Zangezur earthquake

The 1931 Zangezur earthquake occurred on April 27 at 20:50:45 local time with a moment magnitude of 6.5. The earthquake was located in the Zangezur Mountains near the boundary between southwestern Armenia and Azerbaijan's exclave, the Nakhichivan Autonomous Republic. Both territories were part of the Soviet Union at that time.

1977 Sumba earthquake

The 1977 Sumba earthquake occurred approximately 290 kilometres (180 mi) south of Bima, Sumbawa, and beneath the Indian Ocean, at 14:08 local time on 19 August. With a moment magnitude of 8.3, the earthquake is notable for having an unusually great magnitude for a shock with a normal faulting focal mechanism. The shock occurred near the southern section of the Sunda Trench where several other tsunami-generating earthquakes have occurred. The earthquake was at the time the largest outer-rise earthquake ever recorded in Indonesia, and aftershocks along the trench extended about 130 kilometres (81 mi) eastward and 110 kilometres (68 mi) westward from the epicenter.

1999 Ambrym earthquake

The 1999 Ambrym earthquake occurred on November 26 at 00:21:17 local time with a moment magnitude of 7.4 and a maximum Mercalli intensity of VII. The back arc thrust event occurred within the Vanuatu archipelago, just to the south of the volcanic island of Ambrym. Vanuatu, which was previously known as New Hebrides, is subject to volcanic and earthquake activity because it lies on an active and destructive plate boundary called the New Hebrides Subduction Zone. While the National Geophysical Data Center classified the total damage as moderate, a destructive local tsunami did result in some deaths, with at least five killed and up to 100 injured.

1918 San Jacinto earthquake

The 1918 San Jacinto earthquake occurred in extreme eastern San Diego County in Southern California on April 21 at 14:32:29 local time. The shock had a moment magnitude of 6.7 and a maximum Mercalli intensity of IX (Violent). Several injuries and one death occurred with total losses estimated to be $200,000.

1990 Upland earthquake

The 1990 Upland earthquake occurred at 15:43:37 local time on February 28 with a moment magnitude of 5.7 and a maximum Mercalli Intensity of VII. This left-lateral strike-slip earthquake occurred west of the San Andreas Fault System and injured thirty people, with total losses of $12.7 million. Many strong motion instruments captured the event, with an unexpectedly high value seen on water tank near the epicentral area.

2004 Les Saintes earthquake

The 2004 Les Saintes earthquake occurred at 07:41:07 local time on November 21 with a moment magnitude of 6.3 and a maximum Mercalli intensity of VIII (Severe). The shock was named for Îles des Saintes "Island of the Saints", a small island to the south of Guadeloupe, which is an overseas department of France. Although it occurred near the Lesser Antilles subduction zone, this was an intraplate, normal fault event. It resulted in one death, thirteen injuries, and forty people being made homeless, but the overall damage was considered moderate. A small, nondestructive tsunami was reported, but runup and inundation distances were difficult to measure due to a storm that occurred on the day of the event. Unusual effects at a volcanic lake on Dominica were also documented, and an aftershock caused additional damage three months later.

1981 Golbaf earthquake

The 1981 Golbaf earthquake occurred on June 11 at 10:54:25 local time with a moment magnitude of 6.6 and a maximum Mercalli intensity of VIII+ (Severe). Total damage was considered moderate and amounted to $5 million in financial losses, with many injured, and 1,400–3,000 killed.

1974 Lesser Antilles earthquake

The 1974 Lesser Antilles earthquake occurred at 05:50:58 local time on October 8 with a moment magnitude of 6.9 and a maximum Mercalli intensity of VIII (Severe). Four people were injured in what the United States' National Geophysical Data Center called a moderately destructive event.

2000 Banggai Islands earthquake

On 4 May 2000 at 12:21 WITA, Banggai Islands Regency was hit by an earthquake of magnitude 7.5 Mw, followed by a tsunami. The Banggai Islands, an archipelago located at the far eastern end of Central Sulawesi, Indonesia, was the worst affected by the earthquake. Eighty percent of Banggai's buildings were destroyed. Damage also occurred on Peleng. The earthquake triggered a local tsunami of up to 6 m in height that caused significant damage east of Luwuk on the mainland and on Peleng.
