[8] Its peak is 4,207.3 m (13,803 ft) above sea level, making it the highest point in Hawaii and the island with the second highest high point, behind New Guinea, the world's largest tropical island with ...
After hundreds of thousands of years of dormancy, Koʻolau volcano began to erupt again. Some thirty eruptions over the past 500,000 years or so have created many of the landmarks around eastern Oʻahu, such as Diamond Head, Koko Head (Hanauma Bay), Koko Crater, Punchbowl Crater, Tantalus, and Āliapaʻakai, and are collectively known as the Honolulu Volcanic Series, or simply Honolulu ...
The eruption formed a new vent, covered a large area of land with lava, and enlarged the island. The eruption started as a fissure between two pit craters, ʻĀloʻi and ʻAlae, where the Mauna Ulu shield eventually formed. Both pāhoehoe and ʻaʻā lava erupted from the volcano. Fountains of lava surged as much as 540 meters (1772 ft) into ...

They are generally fluid ( VEI -0) Hawaiian eruptions , but more violent eruptions have occurred throughout Kīlauea's eruptive history, with the largest recorded explosive eruption having ...
Oct. 7—Is Mauna Loa about to blow after 38 years of silence ? A couple of weeks of elevated seismic activity and ground swelling on the mountain suggest that might be the case. Is Mauna Loa ...
On Kīlauea's seaward flank (where it is not resting against Mauna Loa) these tendencies are evident where magma oozing out of the caldera turns east and west to form the Southwest Rift Zone (SWRZ) and East Rift Zone (ERZ), both parallel to the shore, [17] and also in the cliffs of the Hilina Pali – coincident with dip-slip faults of the ...
It's been 38 years since Mauna Loa last erupted – the longest recorded quiet period for the volcano, according to USGS. This article originally appeared on USA TODAY: Mauna Loa eruption: What ...
