The Philippine coastguard has said Taal Volcano on the island of Luzon still poses a grave threat as it could erupt at any time, possibly triggering a "volcanic tsunami".

The volcano hurled ash and lava on Sunday as the government declared a state of emergency and moved 38,000 residents to safety.

But despite these warnings, fishermen whose livelihoods are dependant on their daily catch are still venturing into the waters surrounding Taal.
