How it works:
- Earthquakes, volcanoes:
- On the Pacific Ring of Fire with 129 active volcanoes
- Subject to regular earthquakes (~4,000 per year) and volcanic eruptions.
- Due to multiple earthquakes, the Indian and Pacific Oceans experience more and stronger tsunamis.
- Rainy season:
- November to March
- Can trigger flooding and landslides in West Sumatra, Central, East and West Java, Jakarta and mountainous areas.
- Haze caused by forest clearing fires:
- June to October
- Heavily affected areas include Riau Islands, central Sumatra, Kalimantan.
What to do:
- Travel at the “right” time to the “right” place
- Reacting to one:
- Earthquakes: drop (to hands and knees), cover (head and neck with arms), hold on (to sturdy furniture); expect aftershocks.
- Tsunamis: signs include abnormal ocean activity and load roars. Protect yourself from an earthquake first if there is one. Else, get to a high ground as far inland as possible.
- Volcanic eruption: avoid areas downwind and river valleys downstream of the volcano, do not drive in heavy ash fall, seek shelter (if no need to evacuate) or high ground if no shelter (crouch down away from volcano, cover head with arms).
