In such cases, the magma will flow out towards the surface. However, if the magma is thick and dense and gases cannot escape it, it builds up pressure inside resulting in a violent explosion.
According to the US Centers for Disease Control and Prevention CDC , the most common cause of death from a volcano is suffocation, making people with respiratory conditions such as asthma and other chronic lung diseases susceptible. People living close to the volcano or in low-lying downwind areas are also at higher risk in case of an explosion since the ash may be gritty and abrasive and small particles can scratch the surface of the eyes. Further, volcanic eruptions can result in additional threats to health such as floods, mudslides, power outages, drinking water contamination and wildfires.
Lava flows, however, rarely kill people since it moves very slowly, giving enough time to escape. In an interview in , geologist Gail Mahood from Stanford noted that a reason why volcanic eruptions become dangerous in countries like Indonesia, Guatemala and the Philippines as people live very close to the volcanoes owing to its large population.

Note that this map depicts contour elevations in feet, with the surface of the active lava lake now at approximately 2, ft m above sea level.
The scale of the thermal map ranges from blue to red, with blue colors indicative of cooler temperatures and red colors indicative of warmer temperatures. The only remaining active eruptive vent at this time is the west vent; several hotspots in the southern part of the lava lake correspond with short lava cascades between the higher western half and lower eastern half of the lake.
USGS map by M. Several fountains are emerging through the active lake surface, in addition to fountaining on the west margin of the lake. The island remains near the center of the lake, and a small portion of the western cone, active during the previous eruption earlier this year, is still exposed. USGS image by M. The silvery lava recently erupted and spreading away from the west vent, while the darker lava at the margin of the lake is cooled and not moving. This photo was taken from the south rim of the crater.

Lava from an erupting volcano in the Canary Islands has reached the ocean, volcanologists said, raising fear of toxic gases being released as the lava hits the sea water. Lava flowing from Spain's Canary Islands' first volcanic eruption in 50 years has forced the evacuation of 5, people and destroyed around houses but the streams were advancing slower than originally predicted, authorities said on Monday. A surge of lava destroyed around homes on Spain's Canary Islands a day after a volcano erupted, forcing 5, people to leave the area, local authorities said on Monday.
A volcano erupted on the Spanish Canary Island of La Palma on Sunday, sending lava shooting into the air and streaming in rivers towards houses in two villages from the Cumbre Vieja national park in the south of the island.
Japan issued an alert on Friday after a volcano in the southwest of the country erupted, jettisoning large rocks hundreds of metres away from the crater, Kyodo news agency reported. Indonesia's most active volcano Mount Merapi erupted Monday, belching a cloud of ash into the air as red lava flowed down its crater.
Indonesia's Mount Sinabung erupted on Wednesday, spewing a massive column of smoke and ash into the sky. The eruption of the volcano in North Sumatra province lasted about 12 minutes, a local geological agency said.
