No. Plinian eruptions are generally the most destructive. Vulcanian eruptions may be orders of magnitude smaller.

What is the most violent type of volcanic eruption?
Both the Pelean and Plinian eruptions are violent, and the Plinian (such as Vesuvius) are the most spectacular type. More specifically, there is a designation "ultra-Plinian" to describe highly explosive eruptions such as Kratatoa. The type of eruption that is most violent is when lava, ash and other materials are hurled into the air.
Which is more destructive thunderstorm or cyclone?
It can vary, as neither are necessarily destructive, but overall, cyclones have more destructive potential.
Would it be more difficult to deal with an eruption from a near by composite shield or cinder cone volcano?
It would be most difficult to deal with an eruption from a composite volcano. Such eruptions tend te be explosive, spreading ash over large areas, and can produce highly destructive lahars and pyroclastic flows.
What is the biggest eruption of mauna loa?
Mauna Loa volcanic eruption is a magmatic eruption Magmatic eruptions produce juvenile clasts during explosive decompression from gas release. They range in intensity from the relatively small lava fountains on Hawaii to catastrophic Ultra Plinian eruption columns more than 30 km (19 mi) high, bigger than the AD 79 eruption that buried Pompeii
Is a volcano a destructive or constructive process?
If you must choose between one of the two, 'destructive' is the best choice since a geyser eruption never 'constructs' anything. And some enormous eruption might 'destroy' its immediate surroundings.In practice however, geysers are neither of the two. They hardly ever 'destroy' anything, being basically just natural fountains that start randomly or blow water and steam continuously, just like artificial fountains. The do however indicate the presence of volcanic activity in the very near vicinity. And such a volcanic eruption certainly would be labeled 'destructive'.

why are plinian eruptions more violent than hawaiian eruptions apex?
one of the reasons why Plinian eruptions are more violent is that they release more viscous magma than Hawaiian hawaiian eruption.
What kind of eruption was Yellowstone caldera?
The Yellowstone Caldera was formed by an Ultra Plinian eruption. Ultra Plinian is the most violent type of volcanic eruption with enormous columns of ash and gas shooting twenty or more miles into the sky and releasing many cubic kilometers of ash.
What was the death toll in the 1995 soufriere eruption?
The 1995 eruption of Soufriere Hills volcano in Montserrat resulted in 19 deaths. It was a small eruption, but it triggered a larger and more destructive eruption that occurred in 1997, causing further devastation and loss of life.
How high did mount saint Helens erupt?
MT. ST. HELENS ERUPTION (1980)THE PLINIAN COLUMN. The avalanche and lateral blast unloaded a large volume of material sitting above the shallow magma source beneath the north-flank bulge. Pressure-release caused the magma to de-gas violently, and within a few minutes a Plinian eruption column began to rise from the former summit. In 10 minutes it had risen to a height of 20 km, where it spread into a umbrella region driven by high-level winds to the east-northeast. Significant ashfall deposits were produced as far as the Great Plains and minor ash was found even much farther east. As the Plinian eruption grew, it continued to ream out the volcanic conduit. The combined destructive forces of the avalanche, the lateral blast, and the Plinian eruption, resulted in the development of a huge amphitheater (1.5 x 3 km) along the volcano's northern flank.The Plinian eruption lasted for 9 hours. In addition to airfall, the Plinian phase was associated with numerous pyroclastic flows from column collapse. Most of these were directed toward the north and deposited as pumiceous ignimbrites above the avalanche deposit. Some of these pyroclastic flows extended into Spirit Lake and down the North Fork of the Toutle River. The heat provided by the flows resulted in secondary steam explosions that formed large craters (20m in diameter) with ash columns as high as 2000 m. Smaller magmatic eruptions followed the main Plinian blast on May 25, June 12, July 22, and October 16-18. Each of these subsequent events lasted several hours and produced eruptive columns more than 10 kilometers high.
People died in eruption. 100000billion?
No eruption has ever killed 100,000 billion people; bear in mind that the total population of the planet Earth is less than 7 billion. Even the most destructive eruption in history (probably the Thera eruption) probably did not kill more than a few thousand people.
Are volcanes bad or earthquakes?
Both are considered bad. Volcanoes, if the eruption is big enough, can damage a lot of land. However, earthquakes are more frequent and they can be very destructive.
Which is more destructive thunderstorm or cyclone?
It can vary, as neither are necessarily destructive, but overall, cyclones have more destructive potential.
