Russia has no motive to destroy the pipelines it owns. These are valuable, long term assets and the gas that escaped from them yesterday was on its own worth some $600 to $800 million.
A pipeline that could be turned off and on again was a leverage point for Russia that gave it some negotiation power. A destroyed pipeline gives Russia no leverage. This is truly elementary. One can not spin that away.
During the war in Ukraine Russia has not stopped to deliver gas to Europe as contractually agreed. Instead European countries, Poland, Ukraine and Germany have blocked overland and sub sea pipelines that brought gas to Germany.
German people have protested against the U.S. ordered shut down of the Nord Stream II pipeline. (Nord Stream I was recently offline because Siemens was prevented by sanctions from maintaining its compressor turbines.)

Thousands of people in Gera in Germany against Olaf Scholz's policy and the explosion of energy and gas prices. They demand an end to sanctions on Russia and the reopening of the Nord Stream 2 gas pipeline. Demonstrations also in other German cities but EU media censors them.

A day after the protests the pipelines were sabotaged:

HERE IT IS
Footage from the site of a gas leak on the underwater section of the Nord Stream.
The video was published by the Danish military.
Earlier, the Kremlin said that it was most likely about sabotage.
The same opinion was expressed in the German government.

Yesterday's attack on the Nord Stream system is not unprecedented:

In 2015, the annual routine underwater survey of the Nord Stream 1 pipelines came across a remote operated vehicle rigged with explosives right next to one of the lines in Swedish waters.
The umbilical cable had been cut. The drone’s national origin was never disclosed.
In 2015 Pipeline Journal reported:
[T]he Swedish military has successfully cleared a remote operated vehicle (drone) rigged with explosives found near Line 2 of the Nord Stream Natural Gas offshore pipeline system.
The vehicle was discovered during a routine survey operation as part of the annual integrity assessment of the Nord Stream pipeline. Since it was within the Swedish Exclusive Economic Zone (EEZ) approximately 120 km away from the island of Gotland, the Swedes called on their armed forces to remove and ultimately disarm the object.
...
The national identity of the drone has not been verified so far, as many countries use Unmanned Underwater Vehicles (UUVs) of a similar construction, [Jesper Stolpe, Swedish Armed Forces spokesman,] said.
To destroy a sub sea pipeline requires more than a ROV/drone delivered shaped charge.

How strong is a Nord Stream pipe? Quite!
The steel pipe itself has a wall of 4.1 centimeters (1.6 inches), and it's coated with another 6-11 cm of steel-reinforced concrete. Each section of the pipe weighs 11 tonnes, which goes to 24-25 tonnes after the concrete is applied.
It wasn't earthquakes that destroyed the pipelines. These were several well targeted and massive explosions:
A Swedish seismologist said on Tuesday he was certain the seismic activity detected at the site of the Nord Stream pipeline gas leaks in the Baltic Sea was caused by explosions and not earthquakes nor landslides.
Bjorn Lund, seismologist at the Swedish National Seismic Network at Uppsala University, said seismic data gathered by him and Nordic colleagues showed that the explosions took place in the water and not in the rock under the seabed.
The targeted explosions were not small:

Swedish seismologists from Lund University noted that "at least 100 kg of TNT (perhaps more) were used to destroy the pipelines."
