Hawaii's Kilauea volcano continues to erupt, prompting mass evacuations in the southeastern part of the Big Island.

Threat level: The situation is highly dynamic, as lava continues to flow to the surface and the lava lake in the center of the crater sinks, which could lead to bigger problems. According to the U.S. Geological Survey (USGS), the mountain could have an "explosive" eruption as a result of the current draining of the lava lake in the crater.

How it works: If the magma reaches the water table and is then covered by falling rocks, it could lead to an explosive steam explosion. This could hurl huge boulders into the air, and vault ash high into the atmosphere. (It would not be as destructive or violent an eruption as a volcano like Mount St. Helens, however.)

The numbers on Kilauea:

  • 35 years of eruptions: Kilauea has been erupting since 1983, though the recent uptick in activity began on May 3.
  • This one had a 6.9 magnitude earthquake: The current eruption was accompanied by an earthquake on May 4. This was the strongest quake to strike Hawaii since 1975.
  • About 2,000 residents have been forced to evacuate over the last week since lava began flowing out of new fissures in the ground.
  • The eruption caused 24 hours of sustained earthquakes throughout the island, as magma flowed toward the surface.
  • Lava has destroyed 36 structures including 26 homes in the area since May 3.
  • 15 volcanic vents: The Leilani Estates and Lanipuna Gardens neighborhoods are under threat from lava oozing to the surface from more than a dozen ruptures in the ground. There are 770 homes in Leilani Estates, per AP.
  • Unknown date and time: The USGS says that an explosive steam eruption could happen with little to no warning, and would expand the danger zone beyond just the lava fissures.

Business travel might be going out of style

Companies have made it a year and a half mostly without traveling for work — and now more and more of them are considering dramatically reducing business travel to slash costs and cut carbon emissions.

Why it matters: Business travel is a massive part of the global economy — with trillions of dollars and millions of jobs at airlines, hotels and travel agencies hinging on its return.

Local Florida leaders eye ways to take on DeSantis' anti-mask stance

With Florida at the forefront of the nation's COVID surge, local governments across Tampa Bay are wondering if — or how — they can subvert Gov. Ron DeSantis' administration to do something to slow the spread.

Why it matters: A day after Florida broke its record for daily cases, it did the same for the total number of COVID hospitalizations — set way back in July 2020, per the AP.
