Seen a stunning sunrise or sunset lately? The Tongan volcano may be the cause

To understand these sightings, the forecasting team contacted their colleagues at the Lauder Atmospheric Research Station in Central Otago, who confirmed that their ground-based LIDAR (Light Detection and Ranging) instrument has been detecting unusual spikes in aerosols in the stratosphere, at around 20-25 kilometres above New Zealand.

Why Was the Tonga Eruption So Massive? Scientists Have New Clues

Why Was the Tonga Eruption So Massive? Scientists Have New Clues

A team of scientists from New Zealand’s National Institute of Water and Atmospheric Research, or NIWA, recently observed something different.The slopes of the underwater volcano are still largely as they were before the eruption; the same features still contour the surrounding seafloor.

Tonga eruption discoveries defy expectations

Tonga eruption discoveries defy expectations

NIWA’s research vessel, RV Tangaroa , has returned from a month-long expedition as part of the Nippon Foundation-funded Tonga Eruption Seabed Mapping Project (TESMaP), where scientists were studying the effects of January’s eruption of Hunga Tonga–Hunga Ha'apai (HT – HH).

In a rare opportunity to improve understanding of the nature and impact of a major volcanic eruption, NIWA scientists are sailing to Tonga to survey the ocean around the Hunga-Tonga Hunga-Ha'apai (HT–HH) volcano and surrounding regions.

Fossil Pollen Reveals the African Origins of Asia’s Tropical Forests

Fossil Pollen Reveals the African Origins of Asia’s Tropical Forests

New research from Indian scientists has uncovered that the dipterocarp family evolved in Africa and migrated to Southeast Asia via the Indian subcontinent, surviving asteroid impacts and volcanic eruptions along the way.

Scientists Are Racing to Understand the Fury of Tonga’s Volcano

Ten-thousand miles away in England, Simon Proud, a satellite data researcher at the University of Oxford, began to monitor the twitching volcano using an array of satellites.Then, early in the morning on January 14 local Tongan time, a 12-mile-high plume of ash pierced the sky.

The following video shows glass beads being tipped down aerated ramps into water to mimic what happens when pyroclastic flows hurtle down the sides of erupting volcanoes: .

Satellites Can Help Detect When a Volcano's About to Blow

Satellites Can Help Detect When a Volcano's About to Blow

A new study from a Jet Propulsion Laboratory group led by Társilo Girona highlights the possibility that presently available satellite data could provide an entirely new way to warn of eruptions .Heat is obviously a relevant parameter for volcanic activity, but it can be quite variable at the individual spots where you might set up a thermometer.

The ‘Lamborghini’ of Chariots Was Just Unearthed Near Pompeii

The ‘Lamborghini’ of Chariots Was Just Unearthed Near Pompeii

Archaeologists in Italy have unearthed an elaborately decorated, intact four-wheeled ceremonial chariot near the ruins of the Roman city of Pompeii, famously destroyed when Mount Vesuvius catastrophically erupted in 79 CE, BBC News reports.

How to Escape From a Volcano Eruption

How to Escape From a Volcano Eruption

The molten rock chunks blasted up and out will eventually cool and fall, and because the wind at both lower and higher altitudes over Vesuvius on August 24 blew south-southwest, they will drop on Pompeii.

NIWA mapping seafloor around Whakaari/White Island

NIWA scientists are heading to the waters around Whakaari/White Island in the Bay of Plenty next week to survey changes to the seafloor.No-one has collected water column imaging close to Whakaari so this is an incredible opportunity to discover new areas of volcanic activity.”.

Why Volcanologists Didn't Predict New Zealand's Deadly Eruption

Why Volcanologists Didn't Predict New Zealand's Deadly Eruption

On Monday, at 2:11 pm local time, New Zealand’s White Island volcano unexpectedly erupted, blasting a superheated plume of ash, sulfur gas, and steam 12,000 feet in the air and blanketing the crater’s floor in powdered rock and debris.

How Engineering the Climate Could Mess With Our Food

How Engineering the Climate Could Mess With Our Food

Bad news is, the solar shading that would come with geoengineering would negatively affect crops, likely wiping out the gains from lower temperatures.“If we imagine geoengineering as an experimental surgery, our findings suggest that the damages or side effects from the surgery are just as bad as the original disease,” says UC Berkeley agricultural economist Jonathan Proctor, lead author of the new study.A funny thing happens to light when it hits a volcano’s sulfate aerosols in the air.
