Earthquakes have struck Japan’s north-central region of Ishikawa while it is still recovering from the destruction left by a powerful quake in January, but the latest shaking caused only minor damage.
A magnitude 5.9 tremor early on Monday on the northern top of the Noto Peninsula was followed minutes later by a 4.8 tremor and then several smaller quakes within the next two hours, the Japan Meteorological Agency said.
There was no danger of a tsunami.

Two houses that had been damaged in the January 1 quake collapsed in Wajiima city, but no injuries or other damage was reported so far, according to the Fire and Disaster Management Agency.
JMA seismology and tsunami official Satoshi Harada said Monday’s quakes were believed to be aftershocks of the magnitude 7.6 earthquake on January 1. Seismic activity has since slightly subsided, but Harada urged people to be cautious, especially near buildings that were damaged earlier.
Shinkansen super-express trains and other train services were temporarily suspended for safety checks but most of them have resumed, according to West Japan Railway Co.
No abnormalities were found at two nearby nuclear power plants, the Nuclear Regulation Authority said.
One of them, the Shika plant on the Noto Peninsula, had minor damage, though officials said that did not affect cooling functions of the two reactors.
There were no power outages, Hokuriku Electric Power Co. said.
Monday’s rattlings rekindled fear among residents who are still struggling to recover from damages from the New Year’s quake. NHK public television showed a number of people who came out of their homes and temporary shelters to see if there was additional damage.
Reconstruction comes slowly in mountainous areas on the peninsula, and many damaged houses remain untouched.
In Wajima, which was one of the hardest-hit areas, an inn operator told NHK that he immediately ducked under the desk at the reception when the first quake struck Monday.
Nothing fell to the floor or broke, but it reminded him of the January shakings and made him worry that a big quake like that had occurred even five months later.
The January 1 quake killed 241 people. Damages still remain, and many residents remain evacuated.
