Fungal diseases are often caused by fungi that are common in the environment. Most fungi are not dangerous, but some types can be harmful to health. Mild fungal skin diseases can look like a rash and are very common.Fungal diseases in the lungs are often similar to other illnesses such as the flu or tuberculosis.Some fungal diseases like fungal meningitis and bloodstream infections are less common than skin and lung infections but can be deadly. 1  Types of fungal diseases Read about different types of fungal diseases.ungal diseases in the lungs are often similar to other illnesses such as the flu or tuberculosis.

Wave heights of 15 m (50 ft) at that site suggest that the tsunami waves may have been unusually high, 15 to 30 m, along the entire 100-km stretch of coast from Kreung Sabe to the northwest tip of the island.
All types of waves, including tsunamis, have a wavelength, a wave height, an amplitude, a frequency or period, and a velocity. Wavelength is defined as the distance between two identical points on a wave (i.e. between wave crests or wave troughs).Normal ocean waves have wavelengths of about 100 meters. Wave velocity is the speed of the wave. 2  Velocities of normal ocean waves are about 90 km/hr while tsunamis have velocities up to 950 km/hr (about as fast as jet airplanes), and thus move much more rapidly across ocean basins. 3  The velocity of any wave is equal to the wavelength divided by the wave period.
