Kenji Satake Kenji Satake is a Japanese seismologist who has made significant contributions to subduction and tsunami research. Along with Brian Atwater and David Yamaguchi, Satake assembled disparate pieces of information regarding a Japanese tsunami that had no known origin. The three scientists worked together to pinpoint a date, time, and location for the 1700 Cascadia earthquake – 9 p.m on January 26, 1700 – on the Cascadia Subduction Zone off the Pacific Northwest coast of North America.

1700 Cascadia earthquake The 1700 Cascadia earthquake occurred along the Cascadia subduction zone on January 26 with an estimated moment magnitude of 8.7–9.2. The megathrust earthquake involved the Juan de Fuca Plate that underlies the Pacific Ocean, from mid-Vancouver Island in British Columbia, Canada, south along the Pacific Northwest coast as far as northern California. The length of the fault rupture was about 1000 km with an average slip of 20 m .

1946 Vancouver Island earthquake The 1946 Vancouver Island earthquake occurred with a moment magnitude of 7.5 that struck Vancouver Island, on the Coast of British Columbia, Canada, at 10:15 a.m. on June 23. 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.

1707 Hōei earthquake The 1707 Hōei earthquake ("Hōei jishin" 宝永地震 ) struck south-central Japan at 14:00 local time on October 28, 1707. It was the largest earthquake in Japanese history until the 2011 Tōhoku earthquake surpassed it. It caused moderate to severe damage throughout southwestern Honshu, Shikoku and southeastern Kyūshū. The earthquake, and the resulting destructive tsunami, caused more than 5,000 casualties. This event ruptured all of the segments of the Nankai megathrust simultaneously, the only earthquake known to have done this, with an estimated magnitude of 8.6 M. It might also have triggered the last eruption of Mount Fuji 49 days later.

1970 Tonghai earthquake The 1970 Tonghai earthquake occurred at with a moment magnitude of 7.1 and a maximum Mercalli intensity of X ("Extreme"). The strike-slip rupture originated on the Red River Fault, which had not experienced an earthquake above magnitude 7 since 1700, and affected Tonghai County, Yunnan province, China. At least 10,000 people were killed, making it one of the deadliest in its decade. The tremor caused between US$5 to $25 million in damage, felt over an area of 8781 km2 . In Hanoi, North Vietnam, almost 483 km from the epicenter, victims left their homes as the rupture rumbled through the city.

1717 Guatemala earthquake The 1717 Guatemala earthquake struck Guatemala on September 29 with an estimated moment magnitude of 7.4, and a Mercalli intensity of approximately IX ("Violent"). The earthquake essentially destroyed much of the architecture of Antigua Guatemala, which was the colonial capital of Central America at the time. Over 3,000 buildings were ruined including many temples and churches. Such was the effect of the disaster that the authorities considered moving the headquarters to a settlement which was less prone to natural disasters.

1792 Unzen earthquake and tsunami The 1792 Unzen earthquake and tsunami resulted from the volcanic activities of Mount Unzen (in the Shimabara Peninsula of Nagasaki Prefecture, Japan) on 21 May. This caused the collapse of the southern flank of the Mayuyama dome in front of Mount Unzen, resulting in a tremendous tsunami, killing 15,000 people altogether. It was also called "Shimabara erupted, Higo affected" (島原大変肥後迷惑), (Shimabara means the central mountain of the Shimabara Peninsula) since many people were killed by this tsunami in Higo (Kumamoto Prefecture, situated 20 km away across the Ariake Sea).

2003 San Simeon earthquake The 2003 San Simeon earthquake occurred with a moment magnitude of 6.6 on the Central Coast of California, about 7 mi northeast of San Simeon. It occurred at 11:15 PST (19:15 UTC) on December 22. The earthquake probably occurred on the Oceanic fault zone in the Santa Lucia Mountains. It was caused by thrust faulting and propagated southeast from the hypocenter for 12 miles (19 km). The most violent ground movement occurred within 50 miles of the epicenter, though the earthquake was felt as far away as Los Angeles. It was the most destructive earthquake to hit the U.S since the 1994 Northridge earthquake.

2013 Okhotsk Sea earthquake The 2013 Okhotsk Sea earthquake occurred with a moment magnitude of 8.3 at 15:44:49 local time (05:44:49 UTC) on 24 May. It had an epicenter in the Sea of Okhotsk and affected primarily (but not only) Asian Russia, especially the Kamchatka Peninsula where the shaking lasted for five minutes. Due to its great depth (609 km), it was not particularly intense at the surface, but was felt over a very large area. Such a deep-focus earthquake could be felt not only in areas surrounding the Okhotsk Sea but also in places as far as Tokyo (JMA 1) (about 2,374 km away), Nanjing (more than 4,000 km away), Atyrau (MM V) (about 7,196 km away), and Moscow (about 7,370 km away). The shaking prompted almost 900 residents to leave their homes in Moscow.

1931 Dogger Bank earthquake The Dogger Bank earthquake of 1931 was the strongest earthquake recorded in the United Kingdom since measurements began. It had a magnitude of 6.1 on the Richter magnitude scale, and it caused a shaking intensity of III ("Weak") to IV ("Light") on the Mercalli intensity scale. The location of the earthquake in the North Sea meant that damage was significantly less than it would have been had the epicentre been on the British mainland.
