Pacific Disaster Center (PDC)

The Pacific Disaster Center (PDC) tracks a wide range of natural and human made hazards viz. Tropical Cyclone, Earthquake, Flood, Landslides, Wildfire, Drought, Volcanic Eruptions etc to support disaster preparedness, response, and risk reduction efforts.

Collection: `pdc-events`

A STAC collection hold all the PDC events.

Endpoints for Extraction

To get the relevant PDC data, we use the following endpoints:

Get a list of Active Hazards: https://sentry.pdc.org/hp_srv/services/hazards/t/json/get_active_hazards
Get exposure list for each Hazard: https://sentry.pdc.org/hp_srv/services/hazard/{uuid}/exposure
Get exposure details for each exposure: https://sentry.pdc.org/hp_srv/services/hazard/{uuid}/exposure/{timestamp}

Data Schema

The PDCDataSource class when instantiated takes two parameters viz. source_url: str and data: Any.

The data parameter primarily takes a json object of the following format.

{
    "hazards_file_path": str,
    "exposure_timestamp": str,
    "uuid": str,
    "exposure_detail_file_path": str,
    "geojson_file_path": Optional[str]
}

Event Item

A PDC event will always produce an Event STAC Item. Here is a table with the fields that are mapped from the PDC event to the STAC event:

STAC field	PDC Field	Description
id	id	Unique Identifier
geometry	latitude, longitude	Geometric point using latitude and longitude
collection	`pdc-events`
bbox	longitude, latitude, longitude, latitude
datetime	create_Date
title	hazard_Name
description	description
roles	["source", "event"]	Default roles for event item
monty:country_codes	`country` field in the list `totalByCountry`	List of country iso3 are pulled from exposure endpoint by iterating `totalByCountry` field
monty:hazard_codes	type_ID	The hazard codes are generated using the Hazard Type Mapping
asset.report	snc_url	Asset with the link to the PDC report

Hazard Type Mapping

PDC (Pacific Disaster Center) tracks a wide range of natural and geopolitical hazards. The 2025 UNDRR-ISC code is the reference classification for the Monty extension:

Natural Hazards:

PDC Type	GLIDE	EM-DAT	UNDRR-ISC 2025 (Reference)	Cluster	Description
Avalanche	AV	nat-hyd-mmw-ava	MH0801	MH-TERR	Avalanche
Biomedical	EP	nat-bio-epi-dis	BI0101	BIO-INFECT	Infectious Diseases
Drought	DR	nat-cli-dro-dro	MH0401	MH-PRECIP	Drought
Earthquake	EQ	nat-geo-ear-gro	GH0101	GEO-SEIS	Earthquake
Extreme Temperature	HT/CW	nat-met-ext-hea	MH0501	MH-TEMP	Heatwave (or MH0502 for Cold)
Flood	FL	nat-hyd-flo-flo	MH0600	MH-WATER	Flooding (chapeau)
High Surf	OT	nat-hyd-wav-wav	MH0702	MH-MARINE	Wave Action
Landslide	LS	nat-geo-mmd-lan	GH0300	GEO-GFAIL	Gravitational Mass Movement
Marine	OT	nat-hyd-wav-wav	MH0700	MH-MARINE	Marine-related (chapeau)
Severe Weather	ST	nat-met-sto-sto	MH0103	MH-CONV	Thunderstorm

Volcano	VO	nat-geo-vol-vol	GH0201	GEO-VOLC	Lava Flows
Wildfire	WF	nat-cli-wil-for	EN0205	ENV-FOREST	Wildfires
Winter Storm	OT	nat-met-sto-bli	MH0403	MH-PRECIP	Blizzard

Geopolitical & Technological Hazards:

PDC Type	GLIDE	EM-DAT	UNDRR-ISC 2025 (Reference)	Cluster	Description
Accident	AC	tec-mis-col-col	TL0200	TECH-STRFAIL	Structural Failure (chapeau)
Active Shooter	OT	soc-soc-vio-vio	SO0201	SOC-CONF	Armed Conflict
Civil Unrest	OT	soc-soc-vio-vio	SO0202	SOC-CONF	Civil Unrest
Combat	OT	soc-soc-vio-vio	SO0201	SOC-CONF	Armed Conflict
Cyber	OT	N/A	TL0601	TECH-CYBER	Cyber Incidents
Man Made	OT	tec-tec-tec-tec	TL0000	TECH	Technological (general)
Occurrence	OT	N/A	OT0000	OTHER	Other/Unspecified
Political Conflict	OT	soc-soc-vio-vio	SO0201	SOC-CONF	Armed Conflict
Terrorism	OT	soc-soc-vio-vio	SO0203	SOC-CONF	Terrorism
Weapons	OT	soc-soc-vio-vio	SO0201	SOC-CONF	Armed Conflict

Note

All three classification codes (GLIDE, EM-DAT, UNDRR-ISC 2025) should be included in the monty:hazard_codes array for maximum interoperability. More specific hazard codes can be added following the characteristics of the event. For "Extreme Temperature", use MH0501 for heat-related events and MH0502 for cold-related events.

This comprehensive mapping ensures standardized hazard categorization for all PDC tracked hazards, including both natural and geopolitical/technological events.

Hazard Item

A PDC event and the timestamp from exposure endpoint will ALWAYS produce one hazard STAC item. Here is a table with the STAC fields that are managed from the PDC event to the STAC hazard.

STAC field	PDC Field	Description
id	id	Unique Identifier
geometry	latitude, longitude	Geometric point using latitude and longitude
collection	`pdc-hazards`
bbox	longitude, latitude, longitude, latitude

roles	["source", "hazard"]	Default roles for hazard item
monty:country_codes	`country` field in the list `totalByCountry`	List of country iso3 are pulled from exposure endpoint by iterating `totalByCountry` field
monty:hazard_codes	type_ID	The hazard codes are generated using the mapping
asset.report	snc_url	Asset with the link to the PDC report
monty:hazard_detail

Impact item

The PDC events will produce multiple Impact STAC Items when impact related data is available through exposure endpoint.

The following table shows the mapping of PDC impact fields to STAC items.
