Mapping the 100+ aftershocks from the Turkey-Syria earthquake | Maps News

Turkey has been hit by far more than 100 magnitude-4+ quakes given that a lethal 7.8 earthquake struck the southeastern region along the border with Syria on February 6.

Extra than 5,000 folks have been killed with tens of thousands injured across Turkey and Syria after a magnitude-7.8 earthquake and effective aftershocks struck.

The 1st earthquake strike at 4:17am (01:17 GMT) and was centred in Turkey’s Pazarcik district of Kahramanmaras province. Fewer than 12 hrs afterwards, a 2nd 7.6-magnitude tremor rocked the same area.


100+ effective aftershocks

In the course of the earlier 36 hrs, Turkey has been strike by additional than 100 aftershocks of magnitude 4 and larger. Aftershocks are scaled-down earthquakes that manifest in the exact standard location subsequent a major earthquake.

According to the United States Geological Services (USGS), these seismic actions are insignificant readjustments together the portion of a fault that slipped at the time of the primary quake. The frequency of these aftershocks decreases with time.

The toughness of an earthquake is calculated on the Richter scale and recorded on a seismograph. Magnitudes are dependent on a logarithmic scale, which means for each and every entire-amount enhance on the scale, the magnitude is greater by a factor of 10.

While a magnitude 4 aftershock is typically thought of mild, it does consequence in obvious shaking and may possibly lead to minor damage this sort of as cracks on a wall. A magnitude-5 quake, by definition, is 10 occasions additional intense than a magnitude-4 and can trigger moderate damage to properties.

A magnitude-6 earthquake is deemed strong and is 100 instances stronger than a magnitude-4 just one. This kind of earthquake can result in a great deal of hurt, particularly in heavily populated spots.

In the course of the previous 36 hrs, at minimum 81 magnitude-4 quakes, 23 magnitude-5 quakes, 3 magnitude-6 quakes, and two magnitude-7 quakes have been recorded in southeast Turkey.

The animated map beneath shows a time-lapse of all these quakes:

Strongest quake in Turkey since 1999

Turkey is in a person of the world’s most lively earthquake zones. Monday’s 7.8-magnitude earthquake is the most potent to hit the state considering that 1999.

In August 1999, a powerful magnitude-7.6 earthquake shook Marmara, a densely populated location to the south of Istanbul, Turkey’s greatest metropolis, for 45 seconds. In times, the official demise toll stood at 17,500.

Right here is a swift round-up of Turkey’s worst quakes through the earlier 25 decades:
