Massive bushfires in Australia seen from Space
Australia has naturally faced many droughts and bushfires, but conditions have been unusually severe this time. Sometime around September 2019, the bushfires continuously occurred around the state of New South Wales in southeast Australia. The fires had been spreading on a larger scale, and a number of massive fires had merged into a "Mega Fire" that was out of control. The fires are unlikely to end entirely even at the end of January 2020. Figure 1 (left) Standardized Precipitation Index (SPI) in Australia calculated by GSMaP precipitation amount in a month (December 2019), (right)SPI calculated by GSMaP precipitation amount in three months (October-December 2019) in a same way. The relations between SPI value, the range of drought and frequency of phenomenon were classified by WMO (2012). In case SPI value becomes "-1.5 to -1.99", it indicates the situation of "Severe dryness" which happens "once in 20 years". In case SPI value becomes less than -2.0, it corresponds "Extreme dryness" which happens "once in 50 years". These condition shows the possibility of severe drought occurrence which leads to a big social impact. |

JJ-FAST stops deforestation first time at rainy season in Brazil!
JJ-FAST team is developing a next-generation deforestation detection algorithm (version 2) to increase number of deforestation detection, and improve detection accuracy. To validate deforestation sites detected by the new algorithm, a JJ-FAST team visited some sites in Brazil on Feb. 22, 2018. When the team accompanied by IBAMA (Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renovaveis) arrived at one site, a bulldozer was mowing down trees. Two forest loggers were caught red-handed, and the bulldozer was legally seized on site by IBAMA. The team and IBAMA officers also visited another site with ongoing deforestation on Feb. 26, 2018. When the team reached the site around noon, they found two large bulldozers connected with a massive metal chain left unattended. Bulldozers and chain mowing down trees is the typical method to clear-cut large areas quickly. Soon, three workers returned and stood in amazement when they found we waiting for them next to their bulldozers. The men were seized, and the machinery was confiscated on site by IBAMA. Being aware of the possible detection by optical satellites, they looked like they were wondering how their illegal deforestation activities were found under the cloud cover in rainy season. This validation activity was supported by two kind IBAMA researchers, Dr. Edson Sano and Dr. Daniel Freitas, and IBAMA local staffs in Sinop and Junia. The JJ-FAST team is very grateful for this wonderful cooperation with our counterparts in Brazil. |

DAICHI-2 captures tanker oil spill in the East China Sea
In January 6, 2018, Iranian company's tanker "SANCHI" (Panama flag) collided with a cargo ship (Hong Kong flag) in the East China Sea off the east coast of China and a fire broke out. The tanker drifted into Japan's exclusive economic zone (EEZ) not being extinguished and exploded and sank at the sea about 315 km west of Amami Oshima in the afternoon of 14th. Oil is draining from the sunk tanker. |

Agreement concluded with MLIT on DAICHI-2 observation data
JAXA concluded an agreement with the Kyushu Regional Development Bureau of the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) on April 30, 2015, to provide observation data by the Advanced Land Observing Satellite-2 “DAICHI-2” (ALOS-2). The purpose of the agreement is to survey (1) secular changes of landscape and ash fall and (2) isolated islands for their up keep. We will work together to conduct surveys more efficiently with broader covering areas by mutually sharing and studying observation data possessed by the Kyushu Regional Development Bureau and JAXA's satellite data. |

DAICHI-2 captured Mt. Ontake eruption
Mt. Ontake straddling Nagano and Gifu prefectures erupted at 11:52 a.m.
on Sept. 27, 2014. JAXA has been observing the volcanic activity and its
impact by earth observation satellites. The DAICHI-2 acquired data on
Mt. Ontake on Sept. 27, 28, and 29. As it started regular observation
operations in early August and captured some images of Mt. Ontake prior
to the eruption, we can compare images taken before and after the
incident to study changes and the situation. |
