Assessing and Responding to the Beirut Blast through the Use of Imagery and Mapping Techniques

My colleague turned his phone to me and said, “Have you seen this?” Thinking that it was just another funny video created by one of the many internet users who are currently in lock-down due to the COVID-19 pandemic, I braced myself. This time however, it was no joke!

On August 4th, 2020, a warehouse at the Port in Beirut, Lebanon, storing approximately 2,750 tonnes of ammonium nitrate, exploded, destroying nearby buildings and causing damage miles away.

Compare the images below by moving the slider. They show images pre-event on June 9, 2020 and post-event on August 5, 2020. In the image the port warehouses, and the grain silos can be seen. The destruction of the 120,000-ton capacity structure of the grain silo and disabling of the port, the main entry point for food imports, exacerbates concerns about food supplies for Lebanon.

Coincidentally, during my university days in Edinburgh, Scotland, I shared a flat with two amazing ladies who I grew very close to during my year abroad. Thankfully, I still maintain close contact with them, although it has been more than 16 years since we first met. One of them is from Lebanon and the other from Cyprus. Instinctively, upon realizing the severity of the situation that I witnessed in that video, I reached out to them both. My friend from Lebanon, now resides elsewhere. She indicated however, that many of her family members suffered damage to their homes. My Cypriot friend mentioned that they heard the explosion all the way in Cyprus and that it even felt like an earthquake!

Pictured below is a map showing the proximity of Cyprus to Lebanon, an approximate 265 km distance. I couldn’t help but think of the safety of my friends and their families.

As a member of the humanitarian mapping charity – MapAction, I was thankful to learn that a 3 member group was being deployed to help! Even with the rising challenges of operating during the COVID-19 pandemic, this organization, as well as many others are ready to offer support in crisis.

Responding to the Beirut explosion

After being given the opportunity to attend an International Search and Rescue Advisory Group (INSARAG) Earthquake Response Exercise (ERE) in December 2019 in Thailand, I have a deeper understanding and appreciation for the need of collaboration and communication between the teams that are on the ground responding to a disastrous situation. MapAction supports this effort by providing maps to help with co-ordination. The map below shows that in Lebanon, there are several teams on the ground, to include Urban Search and Rescue (USAR), United Nations Office for the Coordination of Humanitarian Affairs (UN OCHA) and the Red Cross. It is quite helpful when co-ordination locations are known by all the teams on the ground.

This is another map that has been provided by MapAction. It shows the area being divided up into more manageable sectors. The locations where bio hazards exist, have been identified and highlighted on the map.

During the past few days, many satellite imagery companies have offered their support to Beirut. This offering is welcomed, as it helps teams on the ground to conduct further damage assessment and provide service delivery to those in need.

The Disasters Charter has also been activated to respond to the Beirut blast. Though clouds obscure parts of this image taken via a Pleides satellite sensor, the map shows emergency shelters being set up, and highlights the location of hospitals in the area.

It is my hope and prayer that Lebanon receives the much needed support and humanitarian relief it requires in the aftermath of this disaster. #prayforlebanon

In my previous blogs I have indicated the importance of up-to-date imagery in responding to a disaster and also what led me to becoming a MapAction Volunteer. You can read them below:

COVID-19: Using Geospatial Resources to Understand the Potential Impact on Our Communities.

On Tuesday March 17, 2020 with a cancelled celebration of St. Patrick’s Day, Montserrat received the dreaded news of its first confirmed case of novel coronavirus COVID-19. For many of us that is when the gravity of this situation hit home, literally!

The Ministry of Health and Social Services (MoHSS), in their press release (http://www.gov.ms/first-case-of-new-coronavirus-covid-19-confirmed-in-montserrat/), reminded members of the public to adhere to the following risk mitigation measures:

  1. Refrain from public gatherings
  2. Maintain social distance and
  3. Wash hands regularly with soap and water or using a hand sanitizer.
  4. Limit non-essential travel

In addition, to the guidelines provided above, the utilization of geospatial services and resources can help prepare, manage and deliver an effective response to COVID-19.

President of Environmental Systems Research Institute (ESRI), Jack Dangermond in a letter addressed to its users, highlighted some steps that can be followed in order to understand the potential impact that COVID-19 can have on our community. Five are outlined below:

  1. Map the Cases – map confirmed cases, deaths and recoveries in order to identify where COVID-19 infections exist and have occurred.
  2. Map the Spread – Time enabled maps can reveal how infections spread over time and where interventions can be targeted.
  3. Map Vulnerable Populations – Mapping factors such as social vulnerability and age can help monitor risk groups
  4. Map Capacity to Respond – Map health facilities, medical resources and employees to understand and respond to potential impacts of COVID-19.
  5. Communicate with Maps – Use interactive webmaps, dashboard apps and story maps to help communicate the situation.

Communication with maps have already been used worldwide to map COVID-19. Webmaps, dashboards and story maps help to visualize the evolving situation.

The dashboard app below, powered by GeoTechVision (https://www.geotechvision.com/) shows the COVID-19 outbreak worldwide. It highlights infections, fatalities and most importantly recoveries.

In an effort to amalgamate information related to COVID-19 in one location, the Government of Montserrat created the Montserrat Coronavirus Response Data Hub: https://montserrat-covid-19-response-data-hub-montserratgis.hub.arcgis.com/. Within the site there is also a dashboard which gives relevant data on the current covid-19 statistics for the island.

The story map below details the origins of COVID-19 and gives an account of its geographic spread in an easy to read interactive dialogue.

Communication through map-based dashboards and story maps such as these offers accessible information to people in our communities and around the world eager to protect themselves. These tools improves data transparency and helps authorities disseminate information quickly and effectively.
