Activation date: 2023-05-23
Event type: Volcanic activity
Activation reason:
Since the summer of 2022, Terceira Island is experiencing an increase in seismic events, mostly located around the Santa Bárbara volcano. Due to the levels of microseismic activity, several evidences, and reports, the Azores Seismovolcanic Information and Surveillance Center (CIVISA) have declared alert V2 (possible reactivation of the system).The Risk & Recovery Mapping service has been activated by the Serviço Regional de Proteção Civil e Bombeiros dos Açores (SRPCBA) to support their activities for risk reduction and preparedness in case of a volcanic eruption in Terceira island. The products generated include:the simulation of the lava flow pathways considering different potential eruption sources and;the level of exposure on the population, both resident and seasonal vacationers, and the infrastructures that could potentially be damaged.Results from these products are deemed sensitive and not appropriate for public distribution.
CEMS-RRMMonitoring areas damaged by forest fires in Serra da Estrela, Portugal (2023-05-02)2023-05-01T20:00:00Z2023-05-01T20:00:00Z<br/>

In August 2022, a wild forest fire affected the Portuguese Serra da Estrela National Park for several days, with strong winds and high temperatures making it difficult for firefighters to control the flames. The Copernicus Emergency Management Service Rapid Mapping (EMSR618) was activated to respond to this event. The fire, the largest in 50 years, resulted in an affected area of about 25,000 hectares, forced the evacuation of several local communities, and caused significant damage to the natural environment, including forests and wildlife habitats. Unfortunately, the devastation did not end there as the wildfires triggered a series of catastrophic floods on 13 September, which further ravaged the region in the following weeks.Several recovery efforts are being implemented to mitigate the effects of the wildfires in various domains. These efforts include the recovery of affected infrastructures such as forest fire defense networks, accessibility networks, and water availability spots. Measures are also being taken to control soil loss, reduce landslide risk, and minimize the risk of flash floods through slope stabilization, re-vegetation of affected areas, and other interventions.The goal of the activation was to assess the current situation within the affected area of interest in terms of vegetation status, land use/land cover, vegetation recovery analysis, and accessibility of the road network. Additionally, the activation aimed to evaluate soil erosion risk, landslide risk, and soil loss by considering the post-fire situation as well as scenarios after the implementation of planned interventions. The following products were requested to support this assessment:1. Current detailed vegetation status at a 1:2,500 scale: This product provides a classification of the current vegetation observed on the most recent aerial component acquisition data (23-26/02/2023). The classification is based on both morphology and height criteria. Photointerpretation keys (PIK) were developed to support the morphological classification. Additionally, a Canopy Height Model (CHM) was calculated from the available Digital Terrain Model (DTM) and Digital Surface Model (DSM) data to extract vegetation height.2. Land-use Land-Cover at a 1:5,000 scale: This product offers an up-to-date land-use/land-cover layer based on the visual interpretation of the aerial component acquisition data (23-26/02/2023). The interpretation relies on the reference national Land Use-Land Cover (LULC) product COS2018, utilizing its level 4 data model.3. Assessment of vegetation recovery: This product evaluates the vegetation recovery at the present date, following the wildfire event. It compares vegetation status using Soil Adjusted Vegetation Index values from satellite images captured in May 2022 (before the event), August 2022 (right after the wildfire), and March 2023. The analysis of vegetation dynamics allows for the assessment of whether vegetation has been eliminated, died, deteriorated, been affected, is recovering, has recovered, or is living.4. Assessment and accessibility of the road network at a 1:5,000 scale: This product provides an accurate and complete road network, including an accessibility status.5. Erosion risk, Landslide risk and Soil loss for different scenarios (actual post fire, future situation after implementation of planned mitigation actions). <br/>
<br/>CEMS-RRMVolcanic risk assessment in Sao Jorge, Azores (2022-05-06)2022-05-05T20:00:00Z2022-05-05T20:00:00Z<br/>

Activation reason: <br/>
The island of São Jorge in the Azores archipelago (Portugal) has been on a V4 high alert since the 23rd March 2022 due to a seismic-volcanic crisis that started on the 19th of the same month, located from Ponta dos Rosais to Norte Pequeno - Silveira area. The most energetic earthquake of this crisis occurred on March 29th, with an epicenter at about 2 km SSW of Velas and a magnitude of 3.8 (Richter). So far, around 271 earthquakes felt by the population have been identified.Under such circunstances, the Autoridade Nacional de Emergência e Proteção Civil (ANEPC), on behalf of the Serviço Regional de Proteção Civil e Bombeiros dos Açores (SRPCBA), activated the Emergency Management Service – Risk and Recovery Mapping with the aim to produce a volcanic risk assessment in São Jorge. The assessment will provide the level of susceptibility estimation for population and infrastructures in the island, by simulating potential lava flow pathways, that will be used to support the emergency management operations, namely for planning of the mitigation and preparedness phases to deal with a possible eruptive event.This activation EMSN129 includes the following products:P01 - Reference dataset that consists of a Geodatabase containing the feature classes representing the up-to-date reference situation based on photointerpretation of VHR1 optical imagery from 2020-2021, and supported on available support data (OSM, Census, Cadastral, CLC, etc), including hydrology, toponyms, physiography, building footprints, transport, industry and utilities, LULC.P02 - Volcanic hazard assessment, consists in the production of Hazard maps through the modelling of the lava flows extents for each of the seven vent locations (lava sources indicated by the user) using the Q-LavHa model and the available DTM with a resolution of 0.5 m which was resampled to 5m for the modelling.P03 - Exposure to people and assets, results from the combination of reference dataset and hazard maps to provide the analysis of exposures and vulnerabilities over the population (low/high season), businesses and most relevant infrastructures affected by the potential lava flows. Main outcomes of the activation are vector data and maps containing reference information, population exposure (for low and high tourism seasons), and assets exposures relative to the seven different lava sources.Results show that the most damaging eruption would be in Velas with more exposed population and assets than for any other lava source location. The less damaging eruption would be originated in the Toledo lava source. <br/>

The scope of the service request EMSN032 is to generate damage delineation and grading maps of 41 different forest fires in mainland Portugal that occurred in July and August 2016. The affected area had an overall extent of 887 km².The service consists of detailed reference maps and damage delineation and grading. Additionally, assessment of post-event slope stability, erosion and accessibility to the affected areas were requested. All layers were produced at the cartographic scale of 1:25,000.The core users are the Autoridade Nacional Proteção Civil (ANPC) and the Institute of Nature Conservation and Forests (ICNF) of Portugal.The damage grading is based on classification of a Sentinel-2 image, acquired after the event, taking advantage of both the NIR and SWIR bands. The NBR (Normalized Burn Ratio) was used for damage grading into 3 classes: Heavily burnt (red), partially burnt (yellow) and not burnt (green). Results were overlaid with land use/cover classes. The maps are accompanied by consequence tables showing the area of each land cover class per burnt category in square kilometres.Erosion Risk was evaluated in terms of soil loss, based on the Revised Universal Soil Loss Equation (RUSLE), a function of rainfall erosivity, soil erodibility, slope length and gradient, the protective influence of vegetation and anti-erosion measures. <br/>

This activation focuses on damage assessment and landslide risk assessment relating to major forest fires in the municipalities of Funchal and Calheta, Madeira in August 2016. Key assets (infrastructure, environment, human life, economic sustainability, etc.) are also identified and related with the severity of impact. The service involves:Post‐disaster assessment referring to loss of forest resources: Damage extent and gradingPre‐disaster mapping through an evaluation and assessment of landslide riskTo optimize the efficiency of the preventative measures to be implemented, risk maps (landslides) and damages maps (burnt areas, grading) at large scale (1:5,000) were generated.The core users are the Autoridade Nacional Proteção Civil (ANPC) and the Institute of Nature Conservation and Forests (ICNF) of Portugal.The method used for burnt area delineation and burnt severity grading is based on thresholding of spectral indices, namely the NDVI and its differentiation in time (dNDVI) derived from pre-fire Pléades image and post fire (two dates) SPOT 6 and 7 acquisitions. Another index which was also calculated and used in combination with the NDVI/dNDVI is the Enhanced Vegetation Index (EVI) and its time differentiation dEVI.For the assessment of landslide risk, the Norwegian Geotechnical Institute (NGI) methodology was employed, which is a function of slope gradient, lithology, vegetation cover and soil moisture and based on a triggering factor of 100 year extreme monthly precipitation. Landslide risk was computed by overlaying the vulnerability assessment with the hazard map and it is categorized at different levels, based on the likelihood of landslide occurrence where assets are exposed, following the risk matrix of the European Commission “Overview of natural and man‐made disaster risks in the EU” (COM 2014).Tables on each map indicate the number of residents, built up surface area, the number of Points of Interest (POIs) and road segments (km) of the exposed elements at various risk levels (Very Low, Low, Medium, High, Very High). <br/>

EMSN034 is a pre-disaster situation analyses to provide thematic information supporting planning for contingencies on vulnerable coastal areas along with a European framework directive on the assessment and management of the flood risk (2007/60/EC). Area of interest is 14 kilometres of beaches in Costa da Caparica, 10 km south of Lisbon, and the belt of land of with width of 1,5 km, along the shore line. Main earth observation data, imagery and digital elevation models, were provided by the activator ANPC (airborne) and JRC (RPAS-borne).Risk and recovery products are oriented to minimize casualties and economic impact in case of Tsunami event. Two sets of coastal flooding and storm surges hazards are developed. First based on computing values of total sea level elevation (SLE) integrating the different components that contribute to total water level during a storm: barometric setup, wind setup, wave setup and astronomical tide, plus a component of sea level rise to account for future climate change. The second approach is constructed based on the creation of a Flood Hazard Index. The four variables that compose the index are breaking wave height, beach slope, nearshore slope and presence of engineering structures. Results for five different probability scenarios ranging from frequent (corresponding to a return period of 5 years) to improbable (corresponding to a return period of 100 years) are calculated.This work is complemented by coastal erosion hazard analyses assessed by constructing an Erosion Hazard Index (EHI), which is composed of three variables: recent rates of shoreline change, presence and characteristics of dunes, and presence of artificial protection structures.Potential suitable locations for first response activities and access roads and evacuation routes are proposed. Mitigation, preparedness and response measures are also described and include, among the others: relocation of sensitive buildings, safe shelters, sand dunes protection, coastal structures, information, warning and alert system, etc. <br/>
