The lava lake level at Kilauea volcano is rising again after fluctuating over the weekend and reaching its highest levels since lava overflowed onto the Halemaumau Crater floor in May of last year.

On Saturday, the lava lake level rose to 16 feet below the crater floor, before dropping to about 44 feet below the floor later Saturday and 66 feet below the floor on Sunday. The lake level began rising again early Monday morning to about 61 feet below the floor of Halemaumau Crater.

The Hawaiian Volcano Observatory released new video and photos of the eruption over the weekend.

The lava spattering is visible from the crater overlook at the Jaggar Museum.

A series of small earthquakes near the summit on Saturday is believed to be related to the rising lava lake levels.

In addition, a magnitude-3.4 earthquake struck Monday morning near Mauna Loa. Over the weekend, a magnitude-3.2 earthquake on Saturday and magnitude-3.0 earthquake on Sunday were recorded in the upper East Rift Zone. Earthquakes in that area are usually related to the movement of magma.
