Contents
This guide will walk you through the
steps for submitting a landslide
report to the Cooperative Open
Online Landslide Repository
(COOLR).
The guide contains:
• Tips for finding landslide events
• Choosing your Landslide Reporter
map and getting started
• Information about every field in the
Landslide Reporter form
• Reviewing/editing/deleting your
reports

Tips for finding landslides
in person
Landslides occur most everywhere,
so you may encounter a landslide in
person along roads, riverbanks, or
any other steep slope.
First things first, make sure you are
a safe distance away from any landslide
you encounter. Even if a landslide has
happened, there is still the possibility of
falling rocks or unstable debris.

• Fresh landslides are best—ones
that have occurred right after a
triggering event like a storm, etc.
• Pictures are worth a thousand
words: take a photo of your
landslide and link to it in Landslide
Reporter from an image hosting
service like Flickr or Imgur
landslides.nasa.gov

50

Tips for finding landslides
online
• There are many resources that
report about landslides:
• Articles in your local newspaper
or an online news source
• Social media feeds like Twitter or
Facebook, using #hashtags or
following specific news sources
• Data entries in local databases
• Disaster and government
agencies
• Setting a Google News Alert will
alert you about new landslide
articles.
• Some keywords to get you started
on finding landslide events:
• Landslide; landslip; mudslide;
debris flow; rockslide; rockfall;
cliff collapse
• Searching in other languages
may help find other events.

51

Choose your Map
There are two ways to add a report to
the database, depending on the
information you have about the slide:
points or polygons.

Points:
The location of
the landslide
can be defined
by a single point.

Polygons:
The location of
the landslide can
be defined by an
area.

landslides.nasa.gov

52

Get Started
Before you begin reporting:
• Do you have your news source
open/ do you have your landslide
notes in front of you?
• Do you have the location of the
landslide? How accurate is that
location?
Click “Submit a Landslide Report” to
begin your report!

General tips:
• Be as detailed as you can!
• Remember to include the source
information
• If you do not have information for a
section, leave it blank or select
“Unknown” from the dropdown box.
landslides.nasa.gov

53

Drawing the Location - 1
The application prompts you for the
location that the landslide originated
from on the map.
Jump to the location as best you can
using the search bar to find the
nearest place or coordinates. Click
on the option that best matches
what you’re looking for.
Click to choose
the coordinates
that match the
location.

Click to choose
the place that
matches the
location.
landslides.nasa.gov

54

Drawing the Location - 2
Define the approximate location with
a single point or with a polygon
shape outlining the area of the slide.
Point
• Click on the map where the
landslide occurred.
• To adjust the location, click another
location on the map.

landslides.nasa.gov

55

Drawing the Location - 3
Polygon
• Click on the map to begin drawing
the area of the landslide.
• Click to add more vertices to the
area’s shape. Double-click to close
the shape’s area.
• To start over and draw a new
shape, click another location on the
map.

landslides.nasa.gov

56

Name and Link of
Information Source
Provide the name and web URL (if
available) of the source you got the
event information from.
• If the source was a database or
media source, provide the name of
the database or media source.
• If the source was from your own
observation, put “in-person
observation” in the form and leave
the link blank.

landslides.nasa.gov

57

Event Date and Time
Provide the date and time that the
landslide occurred.
• If the date is not specified,
approximate the date as closely as
you can and add a comment that
you approximated the date in the
“Event Comments” section.
• If time is not specified, select “Time
not known”

Note: Event time
is the 24-hour
clock format
landslides.nasa.gov

58

Event Title
• Name given in media source: Name
the landslide as closely as you can
to the way it was referred to in the
source (unless the source does not
give it a clear name).
• If the landslide does not have a
name: Title the landslide with a
clear, unique description

Examples:
• State Highway 1 Mudslides at Milepost
35.49 near Davenport
• Snowmass Creek Rd Minor Mudslides, just
below bridge to Snowmass Ski Area
• O'Higgins Region Landslide Swept Away
Car in Chile
• Mid-Hill Highway Dry Landslide along the
Baglung-Burtibang Road

landslides.nasa.gov

59

Event Description
The event description should let
people know the who, what, when,
why of the landslide that has not
been explained in detail.
• Who/what was affected by the
landslide?
• What type of landslide was it?
• When did the landslide occur?
• Why did the landslide occur?

landslides.nasa.gov

60

Location Description
Location description is the detailed
account of where the landslide
occurred.
The space is autofilled with an
address or coordinates based on
where you clicked on the map.
Fill out additional details like you
were filling out an address to mail by
separating city, state, province,
country, etc. with commas.

landslides.nasa.gov

61

Location Accuracy
A radius of uncertainty in the
landslide’s location. The accuracy is
the radius of a circle, whose area is
where the landslide could have
possibly occurred.
Your location
accuracy, a radius
of uncertainty
(e.g. 1 km).

Your point (or
polygon) where
you report the
landslide occurred.
Your point/polygon and location
accuracy represent this shaded
area, which means the landslide is
likely to have occurred anywhere
inside this area.

62

Landslide Category - 1
The type of landslide that occurred.
Use the dropdown menu to select
the best choice. If the event was a
mass movement more detail isn’t
provided, then select “landslide”
from the menu.
Use the following table and figure to
help categorize the landslide.

Landslide Setting
The type of environment in which the
landslide occurred.
This is important to know because
secondary factors like deforestation,
erosion, and human activity could
have contributed to the landslide.

Number of Fatalities and
Injuries
The number of people dead or
injured by the landslide event. This
includes people who died days after
sustaining an injury from a landslide.
If no deaths or injuries occurred, put
a zero in the form. If deaths or
injuries are unknown, then leave
blank.

Imported Event Source
Catalog and Event Source ID
If you are submitting a landslide

an event from.
Event Source ID is the ID of the
event in the source catalog.
If left blank, the Imported Event
Source Catalog will be automatically
filled in with ‘LRC’ or ‘GLC’,
depending on whether the landslide
event is reported through Landslide
Reporter (LRC = Landslide Reporter
Catalog) or by members of our NASA
team (GLC = Global Landslide
Catalog).
