BIG ISLAND (HawaiiNewsNow) -

A 5.4-magnitude quake shook the Big Island on Wednesday amid ongoing eruptions of Kilauea. 

The quake happened about 4:10 p.m. and was located about 2 kilometers west-southwest of Volcano. No tsunami was generated.

U.S. Geological Survey scientists confirmed Wednesday that the quake was triggered by an explosive eruption at the volcano's summit. 

Minutes after the quake, a plume of ash shot about 10,000 feet into the air. Communities downwind are being urged to watch out for falling ash.

For more than a month, the Big Island has been rattled by at least 12,000 quakes. 

On Sunday alone, there were are record 500 tremors. 

Most are centered at the summit of Kilauea volcano, and the vast majority are small (under magnitude 2.5).

But there have also been a number of bigger quakes.

Earlier this week, several temblors above 5.0-magnitude rocked the Big Island.

But the biggest quake so far associated with ongoing eruptions of Kilauea was on May 4, when a 6.9-magnitude tremor shook the island. The temblor was felt as far away as Oahu, and caused some minor damage. 

Chip McCreery, director of the Pacific Tsunami Warning Center, said the quake was the largest to strike the Big Island since November 1975, when a tremor centered two miles off Kalapana Beach was measured at a magnitude 7.2.
