Antarctica has the least earthquakes of any continent, but small earthquakes can occur anywhere in the World.
Which country has the most earthquakes? Japan has the most recorded earthquakes in the world as it sits on a highly active seismic area, but research by the US Geological Survey suggests the answer is not quite as straightforward as it may seem.
More than 200 people are killed and 1,000 are injured in a powerful 7.2-magnitude earthquake which hits south-eastern Turkey; many of the victims are in the town of Ercis, where dozens of buildings collapse.
In 2019, a total of 1,637 earthquakes with magnitude of five or more were recorded worldwide.

The shaking will feel violent and it will be difficult to stand up. The contents of your house will be a mess. A large earthquake far away will feel like a gentle bump followed several seconds later by stronger rolling shaking that may feel like sharp shaking for a little while.
Upsurge in big earthquakes predicted for 2018 as Earth rotation slows. Scientists have warned there could be a big increase in numbers of devastating earthquakes around the world next year. In their study, Bilham and Bendick looked at earthquakes of magnitude 7 and greater that had occurred since 1900.

California and Alaska have the most earthquakes in the U.S.
Few will be surprised to hear that California is the earthquake capital of the U.S. Serious quakes have occurred in recent memory in the state, including the 1989 Loma Prieta quake near San Francisco, which caused 63 deaths.Starting on December 28,
2019, and progressing into 2020, the southwestern part of the island of
Puerto Rico was struck by an
earthquake swarm, including 11 that were of magnitude 5 or greater.

On Dec 26, 2004, a 9.0 magnitude earthquake struck off the Indonesian island of Sumatra, triggering a tsunami that killed tens of thousands of people in several countries.
2, 2019. A strong earthquake struck off the coast of Indonesia's Java island on Friday, swaying buildings as far away as the capital and prompting national authorities to urge those in coastal areas to head to higher ground in case of a tsunami.
2018 Indonesia quakes and tsunamis: Facts, FAQs, and how to help. More than 400 people are reported dead after a tsunami struck western Java and southern Sumatra islands during the evening of Dec. 22, 2018.
On 22 December 2018, a tsunami that followed an eruption and partial collapse of the Anak Krakatau volcano in the Sunda Strait struck several coastal regions of Banten in Java and Lampung in Sumatra, Indonesia.
Q How long does it take a tsunami to reach land? Once generated, a tsunami wave in the open ocean can travel with speeds greater than 800 kilometres an hour (500 miles an hour). These waves can travel across the Pacific Ocean in less than one day. Locally generated tsunamis can reach coastlines in just minutes.
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. When the rocks break, the earthquake occurs.
Usually, it takes an earthquake with a Richter magnitude exceeding 7.5 to produce a destructive tsunami. Most tsunamis are generated by shallow, great earthquakes at subductions zones. More than 80% of the world's tsunamis occur in the Pacific along its Ring of Fire subduction zones.
A tsunami is a large ocean wave that is caused by sudden motion on the ocean floor. This sudden motion could be an earthquake, a powerful volcanic eruption, or an underwater landslide. Tsunamis travel across the open ocean at great speeds and build into large deadly waves in the shallow water of a shoreline.
The greatest run-up height of the tsunami was measured at a hill between Lhoknga and Leupung, on the western coast of the northern tip of Sumatra, near Banda Aceh, and reached 51 m (167 ft). The tsunami heights in Sumatra: 15–30 m (49–98 ft) on the west coast of Aceh. 6–12 m (20–39 ft) on the Banda Aceh coast.
A powerful earthquake off the coast of Sumatra, Indonesia, on December 26, 2004 sets off a tsunami that wreaks death and devastation across the Indian Ocean coastline.

Earthquakes with a magnitude of 5.0 or lower occur almost daily in Indonesia, while more major earthquakes have occurred about once a year throughout the nation's history. These earthquakes often trigger tsunamis or floods that devastate communities.
This is an incomplete list of more recent recorded major earthquakes that have occurred within the boundaries of Indonesia—as indicated by the geology of the region, and the volcanic activity—much large numbers of earthquakes of smaller magnitude occur very regularly due to the meeting of major tectonic plates in the
A powerful quake off the Indonesian island of Java has rattled the capital Jakarta but there appear to have been no major casualties or damage. A tsunami warning after the quake, recorded by US monitors as being magnitude 6.9, was later cancelled.
