A 7.4 magnitude earthquake hit the region near the city of Petropavlovsk-Kamchatsky on the coast of Russia on Sunday, according to preliminary data from the United States Geological Service (USGS).
The event was part of a series of tremors that took place within an hour, causing temporary tsunami alerts to the Kamchatka peninsula and Pacific areas, including Hawaii.
The US tsunamis warning system initially issued a warning to the coast of the Kamchatka Peninsula, which was later canceled by the Ministry of Emergency Russian situations.
Russian authorities ordered the local population not to approach the coast to observe possible waves, noting that the expected wave height would be low, with maximum estimates of up to 60 centimeters in some regions.
In addition to the 7.4 tremor, the USGS recorded other significant shaking in the same area, including 7.0, 6.7 and 6.6 magnitudes, all located about 130 to 142 kilometers east from Petropavlovsk-Kamchasky.
Small additional tremors were also detected, indicating an intense and concentrated seismic activity in the region.

In the United States, the Pacific Tsunamis Alert Center issued alerts to Hawaii, Japan and Atol Midway, which were subsequently canceled after assessment of the situation.
Local authorities in Hawaii even issued a tsunami warning, alerting the population to prepare, but the warning was repealed a few hours later.
