Hurricane Irma, Caribbean and USA

In the first half of September 2017, Hurricane "Irma" caused in the Caribbean and the US serious damage of over 50 billion US dollars. It hit the Leeward Islands, where individual were almost completely destroyed. In the US, there were historic floodings in the Jacksonville region and severe damage due to gale-force winds throughout the state of Florida. "Irma" set several records, among others the longest duration of wind speeds of at least 295 km/h in a tropical cyclone (37 hours).


Report No. 1 (September 8th, 2017)

Report No. 2 (October 9th, 2017)


Hurricane Harvey, Texas (USA)

On 26 August 2017 Hurricane "Harvey" reached a minimum core pressure of 938 hPa and makes landfall as a category 4 cyclone with medium winds up to 215 km / h and peak winds to 260 km / h at 03:00 UTC near Rockport in the US state of Texas Country. This means the strongest landfall of a hurricane in the USA since Charley on 13.08.2004, which brought the fifth highest average winds (240 km/h) since the end of the 19th century.

The first consequences were a lot of damage caused by hurricane, heavy rain, high waves and the storm surge (+2 m in Port Lavaca) until "Harvey" lost the hurricane status at 18:00 UTC.
The atmospheric environmental conditions prevented a rapid weakening and withdrawal of the tropical storm, which led to catastrophic flooding in the large Houston area for several days, during which the many houses were totally immersed under water.

Hurrikan Matthew, Haiti/Bahamas/Cuba/USA

Hurricane Matthew developed over the Caribbean in the end of September and hit the western tip of Haiti with category 4 on the 4th of October.

In the following 24 hours, the hurricane hit the very east of Cuba and the Bahamas. There, he increased in intensity. Afterwards, the hurricane relocated towards the North East in small distance to the coast of Florida and Georgia. The center of Matthew reached the mainland of South Carolina as a category 1 hurricane for a short time on the 8th of October.

High Water/ Flooding in Southern Germany, May/ June 2016

Thunderstorms with extreme precipitation intensities occured in Middle Europe from the end of May till the middle of June 2016. Locally enormous amounts of hail (at least small-grained) fell and even single tornadoes caused damage in a considerable degree.
The greatest potential of damage, however, was associated with heavy precipitation, which locally caused large floods and single landslides.
At some rivers (e.g. Ahr, Kocher), the water levels set new historic highs, elsewhere tidal waves flooded streets with meters of water.
In Germany alone the sincere thundery showers caused a damage in the billions.

Earthquake, Nepal/China/Indien/Bangladesh

The 25 April 7.8 magnitude Gorkha earthquake and subsequent aftershocks, including the 7.3 magnitude earthquake in Dolakha, has caused devastation in Nepal on a scale not seen since the 1934 Nepal-Bihar Earthquake. According to the Government of Nepal, the Gorkha earthquake and aftershocks have severely damaged or destroyed nearly 900,000 buildings and approximately 2.3 million people continue to be displaced. A CEDIM-led research team conducted 284 household surveys in 177 locations spanning 27 Municipalities/VDCs and 7 districts.

The chinese and vietnamese mainland was reached at 18th of July at 06:30 UTC with category 4 in China and with categories 2-3 in Vietnam. Here, gust speed of up to 306 kph were measured.

Supertyphoon 'Haiyan/Yolanda', Philippines


The category 5 typhoon made landfall near Guiuan on Eastern Samar at 07.11 at 20:40 UTC and hit with the strongest landfall wind speeds ever observed. Previously, the typhoon had hit the small nation of Palau causing some damage. Wind gust speeds reached a predicted 380 kph shortly before impact.The warm sea water and low wind shear has contributed to the maximum intensity of this typhoon before landfall. The central pressure was estimated 885 hPa (according Joint Typhoon Warning Center), which makes it only the 5th in 25 years in the Western Pacific to do so (Megi 2010, Flo 1990, Ruth 1991, Yuri 1991). The wind speeds have dropped significantly to around 150 kph approaching Vietnam and Southern China (Hainan). Typhoon dissipated 11.11. over China.

Supercyclon 'Phailin', India


At the beginning of the second decade of October 2013 a very strong cyclone developed over the Bay of Bengal. Super cyclone 02B Phailin showed average wind speeds of up to 259 km/h making the storm a category 5 cyclone, the highest category according to the Saffir-Simpson hurricane scale. Phailin became one of the strongest tropical cyclones ever recorded over the North Indian Ocean. Phailins track led towards the northeast of India, where the tropical cyclone in the federal state of Odisha made landfall and caused enormous damage.

Hurricane 'Sandy', North America

From 25th October on, Hurricane "Sandy" first moved over the Caribbean and then turned in northern direction towards the East Coast of the U.S. and made landfall in New Jersey in the night from 29th to 30th October 2012. CEDIM investigates Hurricane Sandy and its impacts in a near-real time Forensic Disaster Analysis integrating the expertise of CEDIM researchers from various scientific disciplines: Meteorology, Hydrology, Engineering, Geography, Economics, Social Sciences.

Drought U.S.

CEDIM analyzes the drought and record temperatures in the U.S. in spring and summer 2012 and the impact of the drought. CEDIM researchers from different scientific disciplines contribute to the forensic analyses. A first report focusing on meteorological aspects of the drought and heat was released end of August 2012. An updated and extended report focusing also on possible loss and social vulnerability was released on Sepember 24, 2012.

Earthquake sequence, Italy

Two series of strong earthquakes hit the Emilia-Romagna region in northern Italy starting on Sunday, 20.5.2012 and on Tuesday 29.5.2012 respectively, affecting mostly the provinces of Ferrara, Bologna, Modena and Reggio nell'Emilia. The largest event had a moment magnitude of 6.1 and occurred on 20.5.2012 at 4:04 a.m. local time (GEOFON, see GFZ). It was followed by several aftershocks, two having a magnitude of more than 5. The main shock of the second series, having a magnitude of 5.8, happened on 29.5.2012 at 9:00 a.m. and was also followed by two events of more than magnitude 5 on the same day.

Van-Earthquake, Eastern Turkey

The M7.2 Van Earthquake (Eastern Turkey) of 23 Oct. 2011 served as a first example for a forensic approach. Our team consisted of a seismologist, three engineers, a social scientist, an economist, and a meteorologist. Four reports have been produced: immediately after the event on the situation (24.10), a situation up-date (25.10), one addressing shelter issues, in comparison to previous Eastern Turkish Earthquakes (26.10), and a comprehensive overview report (02.11).
