The Hawaiian Volcano Observatory measured a temperature of 103 degrees C (218 degrees F) at a crack in Leilani Estates on Wednesday.
"The kind of eruption that could happen here again would be very similar to the kind of eruption that's going on in Hawaii right now", Kestay said.
But a Flagstaff volcanologist said not to worry, that an increase in tourism traffic would be a bigger hassle than anything volcanoes in the area could cough up.
Scientists say the greatest danger with the blast that could shoot large boulders into the air, is that it may come with little to no warning. If it falls below the water table, water will pour onto the lava, generating steam that will likely explode from the summit in a shower or rocks, ash and sulfur dioxide gases. The observatory noted that such an eruption could generate ash plumes as high as 20,000 feet, which would affect the area of up to 12 miles.
The Leilani Estates community remains in greatest danger, with 15 volcanic fissures so far having destroyed 36 structures, majority homes, and forcing the evacuation of about 2,000 residents.
Since May 3, the State of Hawaii and Hawaii County have spent more than $400,000 in emergency funds to protect life and property from lava flows and earthquakes that have occurred in the Kilauea East Rift Zone.
He said in Volcano, closer to Kilauea's summit where there is the possibility for an explosive eruption at Halemaumau Crater, there is no need for an evacuation, but residents should be prepared to evacuate and for possible falling ash from an eruption.

The Masayoshi Sonled, SoftBank group invested $2.5 billion in Flipkart in August past year through its $100 billion Vision Fund. The investment has nearly doubled, SoftBank CEO Masayoshi Son said on a post-earnings conference call.
If volcanologists can better understand Kilauea and underlying reasons for its seemingly unusual behaviour, Johnson said it could help them better understand other volcanoes.
Kilauea is one of the world's most active volcanoes, and has been erupting continuously since 1983.
Because of the rising fear amongst residents, plant workers removed 50,000 gallons of pentane stored at the site. Residents and officials remained concerned about potential explosions and toxic gas leaks from the plant's underground wells, which provide heat for electricity production.
There have been more than 1,000 earthquakes in the area over the past seven days, with the largest, which had a 6.9 magnitude, on Friday 4.
Officials have warned about high levels of sulfur gas in the air that could threaten the elderly and people with breathing problems.
