Fires in Western Australia April 2015

April 09, 2015

Bushfires are inevitable in the fire-prone landscapes of Western Australia. Long dry summers, vegetation and undergrowth, and ignition from lightning or human causes mean that bushfires can and do occur every summer.

A bushfire is an unplanned fire (in the U.S. this is referred to as a wildfire). Each year Australia's Department of Parks and Wildlife responds to more than 600 bushfires that occur on or near land managed by the department. Bushfires have many causes, some natural such as lightning and some as a result of human activity such as camp fires, escapes from prescribed burning operations, industrial activity such as timber harvesting, mining, farming and power transmission, and some from deliberate arson.

The fires which are indicated by red spots on this satellite image may be bushfires. These are areas where the thermal detectors on the MODIS instrument recognized temperatures higher than background. When accompanied by plumes of smoke, as in this image, such hot spots are diagnostic for fire.The Sentinel hotspot locator on Geoscience Australia show that the fires on this image are up to 24 hours old.

This natural-color satellite image was collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua satellite on April 09, 2015. Actively burning areas, detected by MODIS's thermal bands, are outlined in red.

#537 Science Journalism, Hold the Hype
Everyone's seen a piece of science getting over-exaggerated in the media. Most people would be quick to blame journalists and big media for getting in wrong. In many cases, you'd be right. But there's other sources of hype in science journalism. and one of them can be found in the humble, and little-known press release. We're talking with Chris Chambers about doing science about science journalism, and where the hype creeps in.
