Living With Volcanoes- Indinesia Flashcards
What is the purpose of Indonesia’s Centre for Volcanology and Geological Hazard Mitigation (CVGHM)?
To monitor and mitigate volcanic hazards in Indonesia
Established in 1920, CVGHM focuses on volcano observation and hazard management.
When was the first seismograph set up in Indonesia?
1924
The first seismograph was installed on Mount Merapi.
What natural disaster poses a high threat in Indonesia due to volcanic activity?
Lahars
The threat is exacerbated by ash eruptions and Indonesia’s humid tropical climate.
During which season do lahars pose the biggest threat in Indonesia?
Rainy season (November to March)
High rainfall during this period increases the risk of lahars.
What measures has CVGHM taken to improve monitoring of volcanoes?
Upgraded monitoring instruments and widened geographical coverage
More than 60 volcanoes are now monitored.
What is forbidden on the highest slopes around the crater of Mount Merapi?
Permanent settlement
This is part of the mitigation strategy to reduce risk.
What incentives have been provided to villagers on the southern slopes of Mount Merapi to relocate?
Financial assistance and a small plot of land
These incentives encourage relocation to safer areas.
What is the role of the National Agency for Disaster Management in Indonesia?
To manage disaster response and mitigation strategies
Works in association with CVGHM and researchers.
True or False: The political tension during Indonesia’s emergence into independence prioritized volcanic hazard management.
False
Managing volcanoes was given a low priority during this time.
Fill in the blank: The rainy season in Indonesia contributes to the high threat of _______.
lahars
Ash from eruptions combined with heavy rainfall increases lahar risks.
What types of sophisticated equipment are used to monitor Indonesia’s volcanoes?
Gas emissions, inflation measurements, and earthquake activity sensors
These tools help assess volcanic activity.
How many volcanic hazard zones are indicated on the hazard risk map of Mount Merapi?
Three
Zones include areas affected by pyroclastic flow, lava, ash fall, and lahars.
What is the significance of the volcanic hazard risk map for Mount Merapi?
It identifies areas at risk from volcanic hazards
Helps in planning and mitigation efforts.

Helps in planning and mitigation efforts.
What is a significant challenge faced by people regarding their village sites and family fields?
People have a strong bond with their village site and family fields, often returning, rebuilding, and accepting risks.
What is the economic classification of Indonesia?
Indonesia is a lower-middle-income country.
What resources are limited for Indonesia during an eruption?
Resources that can be deployed once an eruption is underway are limited.
What types of emergency services does Indonesia have?
Indonesia has well-trained and well-equipped emergency services, including the military, experienced in search and rescue.
What facilities are available for evacuation in Indonesia?
Temporary shelters in safe zones are available for evacuation and may be upgraded into permanent residential areas.
What measures have authorities taken to reduce flooding risks?
Authorities have cleared river channels of volcanic material and other debris to reduce the risk of flooding and contain lahars.
What is one commercial use of volcanic material cleared from river channels?
Volcanic material has commercial value for road building.
Fill in the blank: Indonesia has well-trained emergency services, including the _______.
military
True or False: Many farming communities affected by eruptions in Indonesia have abundant resources.
False
What do people living along river valleys use volcanic material for?
Rebuilding houses and community facilities.
