Tuesday’s 6.9 earthquake is said to be the largest within the last 50 years. In 1968, a 7.0 earthquake was reported to have occurred near Trinidad , causing significant damage to neighbouring Venezuela with some damage to Port of Spain.
The 2010 Haiti earthquake resulted in a tsunami which caused at least three fatalities. Trinidad and Tobago experienced tsunamis /’ tsunami -like’ events in 1795, 1825, 1831, 1991 and 1997. It is likely and may be caused by the eruption of Kick ’em Jenny (an underwater volcano located off Grenada) or earthquakes.
The island of Trinidad , off the coast of Venezuela, sits above a risky earthquake zone, a new study reveals. The Central Range fault , previously thought to be inactive, runs through the heart of the island, said geologist and study team member Carol Prentice of the U.S. Geological Survey.
No, earthquakes of magnitude 10 or larger cannot happen . The magnitude of an earthquake is related to the length of the fault on which it occurs . No fault long enough to generate a magnitude 10 earthquake is known to exist, and if it did, it would extend around most of the planet.

An earthquake is caused by a sudden slip on a fault. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel. In California there are two plates – the Pacific Plate and the North American Plate.
Go to an open area away from trees, telephone poles, and buildings. Once in the open, get down low and stay there until the shaking stops. The area near the outside walls of a building is the most dangerous place to be. Windows, facades, and architectural details are often the first parts of the building to collapse.
Indo-Trinidadian and Tobagonians make up the country’s largest ethnic group (approximately 37.6 percent).
Anecdotal evidence abounds of animals , fish, birds, reptiles, and insects exhibiting strange behavior anywhere from weeks to seconds before an earthquake . However, consistent and reliable behavior prior to seismic events, and a mechanism explaining how it could work, still eludes us.
|Magnitude||Earthquake Effects||Estimated Number Each Year|
|6.1 to 6.9||May cause a lot of damage in very populated areas.||100|
|7.0 to 7.9||Major earthquake . Serious damage.||20|
|8.0 or greater||Great earthquake . Can totally destroy communities near the epicenter.||One every 5 to 10 years|
Shallow crevasses can form during earthquake -induced landslides, lateral spreads, or from other types of ground failures, but faults do not open up during an earthquake . If a fault could open up, no earthquake would occur in the first place because there would be no friction locking the two blocks together.
The only scenario where a magnitude 12 earthquake is possible is an impact from an asteroid/comet. The only scenario where a magnitude 12 earthquake is possible is an impact from an asteroid/comet. An impactor that makes it to the surface of the earth transmits approximately half it’s kinetic energy to the ground.
