Hurricane Hector will not be the first tropical cyclone to pass near Hawaii's erupting Kilauea volcano



  Hurricane Hector May Be Close Call to Hawaii

  • Hurricane Hector is expected to pull near or south of Hawaii's Big Island this week, where the Kilauea volcano is located.
  • Several tropical storms have been near the Kilauea volcano in recent years
  • Tropical cyclones can affect other parts of the world where active volcanoes exist

Hurricane Hector is expected to be near or south of Hawaii this week Big Island passing by where the Kilauea volcano has been running for months

Hector would not be the first tropical storm or hurricane passing near the Kilauea Volcano ,

Although rare, every time a tropical cyclone moves near Hawaii over an active volcano and has been doing so for decades. Kilauea has been active since the 1980s, during which time there were seven tropical cyclone landings.

Darby 2016 and Iselle in 2014 are the two recent tropical storms that land on the Big Island and pass right through Kilauea.

This, of course, raises the question of what happens when these two natural phenomena meet.

One thing that can happen is that a tropical storm can trap particles from an erupting volcano.

In 2013, Tropical Storm Flossie passed north of the Big Island and interacted with a portion of icicles and gases from Kilauea resulting in one Study of the University of Hawaii from 2014 led to an increase in lightning by storm.

The flare of lightning occurred near the Big Island as a faltering Flossie approached. Previously, no lighting was detected in Flossie.

"As volcanic emissions were coupled into this humid environment, sulfa aerosols promoted the formation of larger numbers of smaller than normal cloud droplets, which favored charge separation in the upper layers, cloud region and the appearance of lightning," states a press release the study.

Fine particles of the right size and composition (called Cloud Condensation Nuclei or CCN) provide favorable locations where water vapor can condense and form cloud droplets. and volcanoes release fine particles that can act as CCN.

This can temporarily increase the strength of showers and thunderstorms before they rip themselves out.

When this process occurs in the outer bands of a hurricane, the resulting strengthening of the thunderstorms produces heavy rain, pulling the cold air from the top down and forming cold air bubbles near the surface, which allow access to warmer, wetter ones Blocking air into the air Hurricane core that weakens the storm

Typhoon strikes after the eruption of Mount Pinatubo

An extreme example of what can happen when a tropical cyclone drives over an active volcano occurred during the eruption of Mount Pinatubo

From the colossal eruption of Pinatubo in the Philippines in June 1991, Typhoon Yunya, known as Typhoon Diding in the Philippines, arrived in the archipelago.

Yunya hit southern Luzon as the minimum typhoon before moving across the South China Sea. It caused heavy rain and triggered significant flooding on the island.

Although the storm alone caused significant damage, the worst effects were due to Yunya's heavy rains mingling with volcanic ash from the Mount Pinatubo eruption

both natural disasters created numerous large lahars that killed 250 to 300 people.

It should be noted that the amount of large-scale energy released by hurricanes and typhoons is significantly higher – on the order of 2,000 times more energy – than that of volcanoes

where hurricanes and volcanoes coexist

and hurricanes Volcanoes are often active in similar areas, especially in the western Pacific, along a tectonically active strip of land called the Ring of Fire.

The Ring of Fire is Earth's most active location in terms of earthquake activity, but also contains hundreds of volcanoes .

The Pacific Ring of Fire contains hundreds of volcanoes.

Not all volcanoes are along the ring

In addition to Hawaii's Kilauea volcano, there is another one that exists in the tropics of Montserrat's Soufriere Hills volcano in the Eastern Caribbean ,

There are also several volcanoes in the Azores of the Northeast Atlantic, but tropical systems rarely reach this archipelago.
