The earthquakes in Vancouver also appear to have a tidal base. The first of these occurred as an M 6.2 at 2019 UT. This is within minutes of local solar noon, a prime time for tidal triggering when vertical solar effects are maximized.

9 03 03 27 57 2016 40.406 -125.470 10 5.7 Off the Coast of Northern California 10

NEIC reported it was felt with intensity II-III in Ferndale, Loleta, Petrolia, Rio Dell, Samoa, Fortuna, Eureka, Scotia, Hydesville, Bayside, Arcata, Whitethorn, McKinleyville, Redcrest, Myers Flat, Garberville, Trinidad, Blue Lake, Piercy, Bridgeville, Hoopa, Fort Bragg, Laytonville, Crescent City, Mendocino, Albion, Comptche, Elk, Willits, Lewiston, The Sea Ranch, Redding, Anderson, Sonoma, Vallejo, Belvedere Tiburon, San Francisco, Pleasant Hill, Alameda, Boulder Creek, Sparks, Nevada, Hughson, Tillamook, Oregon and in general within about 500 km of the epicenter. A regional foreshock of M 3.0 about 100 km northwest of this epicenter within about 30 minutes of local solar noon may have indicated the tidal promotion of this activity. This event was reported felt with intensity I-II in Crescent City and Eureka, California. This event had been expected in this summary to occur at this time as a result of tidal stresses associated with the eclipse of September 1 combined with effects on North America by landfall of Hurricane Hermine on the coast of Florida.

9 03 12 02 44 2016 36.430 -96.932 5 5.8 Oklahoma

Intensity VI was felt as far as 110 km to the south at Alva and Shawnee City, Oklahoma and V was reported from Kiowa, Stillwater, Kaw City, Carney, Oklahoma City, Bixby, Okmulgee, Shawnee, Coweta, Haysville, Tuttle, Oklahoma and in Andale, Wichita, Mulvane, South Hutchinson, Lindsborg, Ottawa, Kansas; Fort Smith, Arkansas. It was also felt with intensity up to IV as far as 500 km from the epicenter in Missouri, Texas, Arkansas and Nebraska. Minor damage was common but no major damage has been reported at this writing. A considerable amount of light to moderate damage occurred and included, among others, fallen plaster, crumbled brickwork and damage to items that fell from shelves in the shaking. At least one major injury was reported.

It is likely that the earthquake occurred in the Near Islands not in the Andreanof Islands. The location of the previous event in the Andreanof Islands is probably a transcription error (note the epicenter is the same on either side of the International Date Line).

The great Tokyo earthquake. This event caused up to $3 billion (U.S. Dollars) damage. More than 142,000 were killed. A tsunami was generated. This earthquake is usually referred to as the Kwanto earthquake. Up to 38,000 residents of Tokyo were burned to death in an open area where they had congregated following the earthquake for safety. The firestorm which followed the quake destroyed libraries, museums, at collections, archives and scientific data among other irreplaceable structures and items. The earthquake was located in Sagami Bay southwest of Tokyo. At least 15 lines of vertical faults were found with displacement up to 6 feet. Leveling showed uplifts up to 2 meters along the Sagami Bay. The tsunami reached up to 10 meters. Many groundwater effects were observed including pulsating earthquake fountains. More than 128,000 houses were destroyed in the quake and up to 450,000 were burned in the ensuing fire. A hotel built one year earlier with great ability to move (architect: Frank Lloyd Wright) survived with only a few cracks and was used as hospital and first aid station following the earthquake. Building techniques in Tokyo contributed to the firestorm. These included building close to the ground and paper thin walls.

The Charleston, South Carolina earthquake. Up to 60 killed $5 million damage but probably much more. Maximum intensity IX. This earthquake was preceded by four days of small foreshocks which began immediately after an M 8.4 in central Greece. That earthquake may have disturbed the groundwater sufficiently to lubricate the fault responsible for the for the Charleston quakes ultimately triggering the strong event. The mainshock started with an audible noise which gradually became louder to a roar. As the roar began all objects began to shake. This shaking accelerated and frightened many. The initial shock caused many to gather in public places and was followed eight minutes later by a second shock. Further aftershocks continued and further damaged buildings. Railroads and telegraphs were damaged although many fled the area. A tsunami was generated which was observed in Jacksonville, Florida and on the Cooper River. Sulfur gas was evident in the Charleston area. Because much of Charleston was built on landfill liquefaction, amplified shaking and sand blows were all very evident. Chimneys of more than 14,000 homes fell. Three-story buildings showed damage to second story and at the top (this same phenomena caused by the wavelength of vertical waves moving upward through the building was observed in the Kobe, Japan quake of 1995). Wooden buildings fared better than stone. Apparently there were two epicenters for this event - one near Woodstock northwest of Charleston and the other due west of Charleston. Fissures were common in the ground and water extruded from cracks in some cases in high jets. Rails were bent. The quake was felt over an area of more than 1300 km - up to about 2 million square miles. Severe damage occurred at Savannah and Columbia, S.C. Some damage occurred at Augusta, Raleigh, N.C. and Wilmington, N.C. Also felt in Boston, MA, Milwaukee, Wis and Cuba. Felt strongly at New York City. An strong unnamed hurricane passed offshore Charleston on August 24, 1886.

12,000-15,000 killed with maximum intensity X at Dasht-e-Biaz, Iran. Known as the Dasht-e Bayaz earthquake. Disastrous in Khorasan. Many villages were completely destroyed over an area of 4,000 sq. km. 12,000 homes destroyed and more than 70,000 people were left homeless. At Dasht-e Bayaz 3,000 of the 3,500 population were killed most buried under the ruins. Mosques and other public buildings were also destroyed. Two mosques up to 300 years old were destroyed. Adobe houses were almost all completely destroyed however brick buildings held up much better. The main destruction occurred along the fault line which was up to 300 meters in places but damage occurred for tens of km from the fault.

This is the strongest earthquake ever recorded in Canada. Animals and people on Queen Charlotte Islands (Graham Island) were knocked down by the shaking. Chimneys fell and oil tanks collapsed in Terrace. Cars were moved about on the road. At Delkatla, the bridge "writhed like a snake" and the ground was cracked. Horses in the epicentral area became restless up to an hour before the quake and could not be controlled. One crack across the Delkatla Slough was 50 feet long and 6 inches across and the bottom could not be located. Trees were felled in the epicentral area. At Prince George alarmed people ran into the streets. The event was felt from Portland, OR to Jaspar, Alberta, Canada. An area of more than 2 million square miles was affected. As the surface waves passed Ottawa more than 3500 km distant astronomers were unable to use telescopes as the shaking was too great. A surveyor in the Arctic reported he could not find his position as the cross hairs in his telescope could not be held steady.

8 19 5 33 30 1961 36.017 136.767 17 7.3 No. Honshu, Japan

This earthquake known as the Kita Mino earthquake occurred in an area known for destructive earthquakes. The epicenter was located in the Haku-San National Park. 9 killed and 36 injured most from falling rocks. The earthquake was followed by many aftershocks. An unusual distribution of first motions for this earthquake does not follow the normal pattern and the nature of this shock is questionable. It is very likely that this is a classic example of a large shock triggered by a seismic wave from another strong earthquake. The timing between the Peru event and the succeeding Honshu quake is 23 min. 40 sec. The distance between these events is 144 degrees. A core reflection from Peru (PKS or SKP) would have arrived at the Honshu epicenter within 10-15 seconds of the initiation of the rupture in Japan. It seems likely that this phase initiated the deadly earthquake in Honshu.

One of the most powerful historical earthquakes in the Yellowstone area. This event is referred to as the Hebgen Lake earthquake. A great and disastrous avalanche occurred on the south wall of the Madison River Canyon forming a barrier that blocked the gorge and flow of the lake and created a lake 175 feet deep. 28 were killed in this and other nearby slides. Fault scarps occurred up to 21 feet high near Red Canyon Creek. Homes in Hebgen Lake were badly damaged. Many roadways were damaged with total coast up to $11 million U.S. Dollars. The strongest intensity was VIII in northern Yellowstone Park. New geysers formed and hot springs became muddy. Minor damage was observed from Montana, Idaho and Wyoming. Felt throughout western U.S. from Seattle, Washington to Rapid City, So. Dakota on the east and from Elko, Nevada to Regina, Saskatchewan, Canada.

This earthquake was not well located at the time but was relocated at a later date. Dynamic S-waves from this earthquake were probably instrumental in triggering the earthquake in Chile 30 minutes later which was damaging and deadly.

8 17 0 40 0 1906 -33.000 -72.000 60 8.6 Central Chile

Known as the great Valparaiso Earthquake. This was the first fully documented Chilean quake from the modern point of view. The epicenter was near Valparaiso and maximum intensity IX-X extended to the north for several hundred km in which area considerable damage occurred (from Papudo and eastward to Tiltil and Melipilla. Santiago felt the quake with intensity VIII. Two ships offshore were damaged by the seaquake (shaking at sea from an earthquake). On the S.S. Thuringa gangway plates were thrown in the air and damage and leaking from the hull was found. A 50-ton crane fell over and narrowly missed the docked ship. On the S.S. Varda it was feared the ship would break in two and lifeboats were released. Pipes broke and water flooded the engine room but the anchor was not lost. The lower part of Valparaiso was largely destroyed probably due to its location on landfill. A fire followed and destroyed much of the city built on hillsides. A tsunami followed with maximum amplitude of 2-3 feet. A tsunami in Japan was probably the result of the Andreanof Islands earthquake which occurred half an hour earlier. Coastal uplift occurred up to about 1 meter especially at Valparaiso but the uplift was not permanent and later subsided. Felt throughout much of South America from off the eastern Seaboard (aboard a ship off the Atlantic coast of Patagonia) to Buenos Aires, the Juan Fernandez Islands and Peru.

An earthquake off Tanabe, Wakayama Prefecture triggered a tsunami observed at Genko Island. The tsunami caused the sea first to recede and then to agitate. About 20 ha were uplifted and upheavals occurred at Senrigahama (Minabe-machi).

8 14 2 0 0 1868 -18.500 -71.000 0 8.5 So. Peru/Bolivia

This was one of the most widely investigated earthquakes in South America. Damage occurred throughout southern Peru and northern Chile from Guayaquil on the north to Valparaiso on the south. About 150 were killed in Moquequa alone and 3000 in the region of Arequipa but the total number of deaths ranged from several hundred to an estimated 40,000. Many of the dead were killed by the tsunami while seeking protection from the earthquake at sea walls. Arequipa, Moquegua, Mollendo, Ilo and Arica and other villages and towns in the area were largely destroyed. A tsunami was generated which was observed throughout the Pacific Ocean and did damage in New Zealand, Australia, Samoa, Hawaii, California and Japan. At Isla, Peru the sea withdrew suddenly and after a delay of 20 minutes in Arica the first wave reach with maximum height up to 17 meters. This tsunami destroyed what was left of Arica. The third or fourth wave was the highest and was described as a wall of water up to 45 feet high. This wave carried several ships as much as three miles inland where they lay for more than 50 years afterwards. A series of foreshocks preceded the earthquake. Cracks formed near Arica which were 5-8 cm wide and issued flows of mud, water and asphyxiating gasses. The air was charged with electricity such that sparks were observed when fingers were run through dry hair. Earthquake lights were observed throughout the Andes as moving balls of light. Waves could be seen passing over the surface of the earth.
