It was 1:47 of the 21st of September 1999, when a Mw7.7 earthquake at the Chelungpu Fault struck the town of Chi-Chi (or Jiji), in Nantou county, central Taiwan.

https://earthquake.usgs.gov/earthquakes/eventpage/usp0009eq0/

The devastation was huge and so were the human losses:

2400 people killed, 8700 injured and 600,000 homeless.

Dams and bridges were destroyed and landslides created new lakes.

https://doi.org/10.1785/0120000738

It was also felt in Mainland China, including Hong-Kong, and in the Japanese Ryukyu islands.

During the last seven hours, there were four earthquakes with magnitudes varying from 4.5 to 4.9 in the south of the Chocó department, situated in western Colombia.

Fortunately, none of them was shallow.

It was the 6th of September 1833, when a Mw8.0 earthquake ruptured a large segment of the Xiaojian Fault, in the Songming Fault, not far from Kunming, the capital of the southern Chinese province of Yunnan.

https://doi.org/10.1016/j.pepi.2008.04.013

https://doi.org/10.1016/j.pepi.2008.04.013

Due to the tremendous violence of the earthquake, the authorities estimated that more than 80,000 buildings were destroyed and 6,707 people were killed in the affected areas, in great part in consequence of the huge landslides.

https://gallica.bnf.fr/ark:/12148/bpt6k54370177

Analysing the known history of earthquakes along that fault, the 1833 event is incomparably greater than any other seismic convulsions in the last five centuries.

https://doi.org/10.1016/j.pepi.2008.04.013

That poses the question, not yet answered: when there will be a similar earthquake there?

It was 39 minutes past midnight of September 5, 1944, when a Mw5.7 earthquake, the largest known so far in the New York state, hit Massena, a town very close to the border with Canada and the St. Lawrence river.

https://earthquake.usgs.gov/earthquakes/eventpage/iscgem899531/

Apart from much panic, the earthquake caused significant damage in Massena and in the neighbouring town of Cornwall, in Ontario, Canada.

It was felt through a very large geographical area, which comprised in the US all New England and great part of Michigan, Ohio, Pennsylvania, and Maryland.

It was around midday, on the 1st of September 1923, when a Mw8.0 earthquake (followed by strong aftershocks in the next minutes), originated at the Sagami Trench struck the Kanto plain, in central Honshu, Japan.

Although many residents were crushed by falling buildings and debris, wildfires created veritable firestorms that accounted for almost 90% of the casualities.

https://en.wikipedia.org/wiki/Great_Kant%C5%8D_Earthquake

Tokyo and Yokohama were among the most severely hit cities. Half of the first city and nearly the entire second were destroyed, leaving 2,500,000 people homeless.

The advertiser-journal. volume AUBURN NY September 01, 1923, Page 1

The Republican-journal OGDENSBURG NY September 04, 1923, Page 1

The death toll was colossal - estimates vary from 105,000 to 140,000. Besides its human and economical heavy impact, the Kanto earthquake had also political implications. In the aftermath of quake, groups of vigilantes - with the complicity of several police officers and government officials - killed thousands of Koreans, along with anarchists, socialists, and communists. Some even say that isolation of Japan was another consequence, paving the way to the invasion of China and later Pearl Harbour.

It was 9:51 p.m. on August 31, 1886 when a Mw6.9 earthquake violently hit Charleston, South Carolina, destroying many buildings and killing 60 people, which makes it the deadliest earthquake in the US East coast.

https://doi.org/10.3133/cir985

Although damage was concentrated in South Carolina, the earthquake was felt throughout the Eastern half of the United States, including Boston and even Chicago.

The violence of the earthquake surprised everyone, as the area was considered safe in terms of earthquakes. Till then...

On the 31st August 2025, a Mw6.0 earthquake hit the province of Kunar, in northeastern Afghanistan, not far from the border with Pakistan.

It was a shallow earthquake and the affected area is very poor, where most village houses were made of mud-brick.

Heavy rains in the previous days facilitated the occurrences of landslides.

Strong aftershocks in the following days added destruction and victims.

MANILA STANDARD 3 September 2025

The effects of recent war and the Taliban censorship and restrictions about female medical staff worsened the situation, namely among the women.

Although numbers might be even higher, the official estimates point to about 2,200 deaths and almost other 4,000 people injured.

On the 29th of August 1420 (September 7, according to the Gregorian calendar) a tsunami hit the coast of Honshu, Japan, but no earthquake was reported. That was what they call an "orphan tsunami"

https://cir.nii.ac.jp/crid/1520290882585459200

https://cir.nii.ac.jp/crid/1520290882585459200

The mystery seems to have been solved with the recent discovery of a field of large boulders in the coast of the desert of Atacama in northern Chile.

https://cir.nii.ac.jp/crid/1520290882585459200

https://cir.nii.ac.jp/crid/1520290882585459200

https://cir.nii.ac.jp/crid/1520290882585459200

The dating of the boulders (between 1408 and 1449 AD) and the size of the causing earthquakes (magnitude between 8.8 and 9.4) match quite well with the tsunami that reached the Japanese coast in 1420.

By the way, it wouldn't be the first nor the last time that a giant earthquake with epicenter close to the South American coasts produced a tsunami that affected the Japanese coasts.

An almost forgotten earthquake, but with a very heavy death toll.

It was 3:51 a.m. of the 28th August 1973, when a Mw7.1 inermediate-depth (depth=84 km) earthquake struck near the triple border of the Oaxaca, Veracruz and Puebla states in Mexico.

https://earthquake.usgs.gov/earthquakes/eventpage/usp000038k/executive

Many buildings collapsed, namely in Orizaba and Ciudad Serdán, killing hundreds of people.

The true death toll is not known and estimates vary from 527, to 1000, 1200 and even 3000 desths, making it the second more deadly Mexican earthquake, just surpassed by the 1985 earthquake.

On the 26th August 2024, that is, two years ago, a M5.3 earthquake woke up (it was 5:12 A.M.) and frightened thousands of people in the Greater Lisbon, Portugal, and throughout the country.
The epicenter was located in the Atlantic Ocean, offshore Sines, town situated in the coast of the Portuguese Alentejo region.

Weeks of aftershocks followed the event.

By a curious coincidence, on another 26th of August, but in 1966, a relatively large (M4.7) earthquake located not very far from this one, but inland, was felt throughout the center and the south of Portugal.

Considered by many as similar to the 1755 Lisbon event, the M7.5 earthquake of August, 24 1356 caused great destruction in Lisbon and Seville, although the number of victims is nok known.

The epicenter was possibly located southwest of the Cape Saint Vincent, Algarve, Portugal, but it was violently felt throughout all the south of the Iberian Peninsula.

On the 22th of August 1902, by 3h01 TUC, a Mw7.7 earthquake at the Tien-Shan range violently struck the regions of Kashgar and Artux/Atushi/Artush in the westernmost province of Sinkiang (China), close to the border with Kyrgyzstan.

Felt in most Central Asia, the earthquake caused grat destruction, killing at least 2500 people, although other estimates put numbers as high as 10,000 deaths.

Apesar da sua baixa magnitude, como teve uma profundidade de apenas 1 km, é possível que alguém o tenha sentido, especialmente se estava em repouso num andar superior.

Por exemplo, ainda em Maio foi sentido um de magnitude 1,8 apenas, perto de Oliveira de Azeméis.

On the night of 12 to 13 August 1948, near midnight (local time), a M5.2 earthquake struck at Condeixa-a-Nova, in the proximity of Coimbra, Portugal, causing some damage and much panic among the residents.

It was widely felt in the northern half of Portugal.

Several aftershocks followed.

Ainda se recordam do medo que os lisboetas sentiram com os sismos de Agosto de 2024 e de Fevereiro de 2025? Pois há um século atrás foi ainda pior...

Eram as 22h10 da noite do dia 9 de Agosto de 1903 no Reino de Portugal, quando um sismo com a magnitude estimada de 5,5 e epicentro ao largo de Sesimbra, sacudiu violentamente a Área Metropolitana de Lisboa, sendo sentido por todo o país e ainda em boa parte do sul de Espanha.

https://www.casadasciencias.org/recurso/7321

O pânico foi imenso e generalizado entre os lisboetas e houve mesmo alguns pequenos estragos nas paredes e mobiliário.

Alguns ainda se recordavam do mortífero terramoto de Setúbal, em 1858.

Desta vez, felizmente, não houve vítimas.

Tanto a imprensa nacional, como a internacional, fizeram eco do acontecimento.
